Helianthus annuus
–
Helianthus annuus, the common sunflower, is a large annual forb of the genus Helianthus grown as a crop for its edible oil and edible fruits. This sunflower species is used as bird food, as livestock forage. The plant was first domesticated in the Americas, wild Helianthus annuus is a widely branched annual plant with many flower heads. The domestic sunflower, however, often only a single large inflorescence atop an unbranched stem. Sunflower seeds were brought to Europe from the Americas in the 16th century, the plant has an erect rough-hairy stem, reaching typical heights of 3 metres. The tallest sunflower on record achieved 9.17 metres, Sunflower leaves are broad, coarsely toothed, rough and mostly alternate. What is often called the flower of the sunflower is actually a head or pseudanthium of numerous small individual five-petaled flowers. The outer flowers, which resemble petals, are called ray flowers, each petal consists of a ligule composed of fused petals of an asymmetrical ray flower. They are sexually sterile and may be yellow, red, orange, the flowers in the center of the head are called disk flowers. The disk flowers are arranged spirally, typically, there are 34 spirals in one direction and 55 in the other, however, in a very large sunflower head there could be 89 in one direction and 144 in the other. This pattern produces the most efficient packing of seeds mathematically possible within the flower head, most cultivars of sunflower are variants of Helianthus annuus, but four other species are also domesticated. This includes H. tuberosus, the Jerusalem Artichoke, which produces edible tubers, a model for the pattern of florets in the head of a sunflower was proposed by H. Vogel in 1979. It is a form of Fermats spiral, the angle 137. 5° is related to the golden ratio and gives a close packing of florets. This model has been used to computer graphics representations of sunflowers. The sunflower, Helianthus annuus, genome is diploid with a chromosome number of 17. Some sources claim its true size is around 3.5 billion base pairs, to grow best, sunflowers need full sun. They grow best in fertile, moist, well-drained soil with heavy mulch, in commercial planting, seeds are planted 45 cm apart and 2.5 cm deep. Sunflower whole seed are sold as a food, raw or after roasting in ovens

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plantae
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Eudicots
–
The eudicots, Eudicotidae or eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors. The close relationships among flowering plants with tricolpate pollen grains was initially seen in studies of shared derived characters. These plants have a trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Later molecular evidence confirmed the basis for the evolutionary relationships among flowering plants with tricolpate pollen grains. The term means true dicotyledons, as it contains the majority of plants that have been considered dicots and have characteristics of the dicots, the term eudicots has subsequently been widely adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other. The remaining angiosperms are sometimes referred to as basal angiosperms or paleodicots, the other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen, or forms derived from it and these pollens have three or more pores set in furrows called colpi. In contrast, most of the seed plants produce monosulcate pollen. The name tricolpates is preferred by some botanists to avoid confusion with the dicots, numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Most leafy trees of midlatitudes also belong to eudicots, with exceptions being magnolias and tulip trees which belong to magnoliids, and Ginkgo biloba. The name eudicots is used in the APG system, of 1998 and it is applied to a clade, a monophyletic group, which includes most of the dicots. The eudicots can be divided into two groups, the basal eudicots and the core eudicots, basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group, a 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots

Asterales
–
The order is a cosmopolite, and includes mostly herbaceous species, although a small number of trees and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor, Asterales share characteristics on morphological and biochemical levels. Synapomorphies include the presence in the plants of oligosaccharide inulin, a nutrient storage molecule used instead of starch, under the Cronquist system of taxonomic classification of flowering plants, Asteraceae was the only family in the group, but newer systems have expanded it to 11. In the classification system of Dahlgren the Asterales were in the superorder Asteriflorae, the order Asterales currently includes 11 families, the largest of which are the Asteraceae, with about 25,000 species, and the Campanulaceae, with about 2,000 species. The remaining families count together for less than 500 species, the phylogenetic tree according to APG III for the Campanulid clade is as below. The core Asterales are Stylidiaceae, APA clade, MGCA clade, other Asterales are Rousseaceae, Campanulaceae and Pentaphragmataceae. All Asterales families are represented in the Southern Hemisphere, however, Asteraceae and Campanulaceae are cosmopolitan, less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub. Because all clades are represented in the southern hemisphere but many not in the northern hemisphere, Asterales are angiosperms, flowering plants that appeared about 140 million years ago. Asterales contain about 14% of eudicot diversity, however few fossils have been found, of the Menyanthaceae-Asteraceae clade in the Oligocene, about 29 Mya. Fossil evidence of the Asterales is rare and belongs to rather recent epochs, an Oligocene pollen is known for Asteraceae and Goodeniaceae, and seeds from Oligocene and Miocene are known for Menyanthaceae and Campanulaceae respectively. The Asterales, by dint of being a super-set of the family Asteraceae, include some species grown for food, including the sunflower, lettuce, many are also used as spices and traditional medicines. Asterales are common plants and have many known uses, for example, pyrethrum is a natural insecticide with minimal environmental impact. Wormwood, derived from a genus that includes the sagebrush, is used as a source of flavoring for absinthe, despite the large number of species in order Asterales, they do not compare in economic benefit for mankind to the Poales or to the Fabaceae. The Asteraceae include many plant species in North America. W. S. Judd, C. S. Campbell, E. A. Kellogg, P. F. Stevens, plant Systematics, A Phylogenetic Approach, 2nd edition.

Asteraceae
–
Asteraceae or Compositae is a very large and widespread family of flowering plants. The family currently has 32,913 accepted species names, in 1,911 genera and 13 subfamilies, in terms of numbers of species, the Asteraceae are rivaled only by the Orchidaceae. Many members have composite flowers in the form of flower heads surrounded by involucral bracts, when viewed from a distance, each capitulum may have the appearance of being a single flower. The name Asteraceae comes from the type genus Aster, from the Greek ἀστήρ, meaning star, Compositae is an older but still valid name which refers to the fact that the family is one of the few angiosperm ones to have composite flowers. Most members of Asteraceae are herbaceous, but a significant number are also shrubs, vines, the family has a worldwide distribution, from the polar regions to the tropics, colonizing a wide variety of habitats. It is most common in the arid and semiarid regions of subtropical, the Asteraceae may represent as much as 10% of autochthonous flora in many regions of the world. Asteraceae is an important family, providing products such as cooking oils, lettuce, sunflower seeds, artichokes, sweetening agents, coffee substitutes. Several genera are of importance, including pot marigold, Calendula officinalis, Echinacea, various daisies, fleabane, chrysanthemums, dahlias, zinnias. Asteraceae are important in medicine, including Grindelia, yarrow. A number of species are considered invasive, including, most notably in North America, dandelion, the name Asteraceae comes to international scientific vocabulary from New Latin, from Aster, the type genus, + -aceae, a standardized suffix for plant family names in modern taxonomy. The genus name comes from the Classical Latin word aster, star, Compositae, an older but still valid name, means composite and refers to the characteristic inflorescence, a special type of pseudanthium found in only a few other angiosperm families. The study of family is known as synantherology. The vernacular name daisy, widely applied to members of family, is derived from its Old English name, dægesege, from dæges eage. This is because the open at dawn and close at dusk. Composite flowers have a distribution, and are found everywhere except Antarctica. They are especially numerous in tropical and subtropical regions, Compositae were first described in 1792 by the German botanist Paul Dietrich Giseke. Traditionally, two subfamilies were recognised, Asteroideae and Cichorioideae, the latter has been shown to be extensively paraphyletic, and has now been divided into 12 subfamilies, but the former still stands. The phylogenetic tree presented below is based on Panero & Funk updated in 2014, the diamond denotes a very poorly supported node, the dot a poorly supported node

Heliantheae
–
The Heliantheae are the third-largest tribe in the sunflower family. With some 190 genera and nearly 2500 recognized species, only the tribes Senecioneae and Astereae are larger, the name is derived from the genus Helianthus, which is Greek for sun flower. Most genera and species are found in North America and South America, most Heliantheae are herbs or shrubs, but some grow to the size of small trees. Leaves are usually hairy and arranged in opposite pairs, the above statements about the size and distribution of the tribe apply to a broad definition of Heliantheae, which was followed throughout the 20th century. Some recent authors break the tribe up into a dozen or so smaller tribes, commercially important plants in the Heliantheae include sunflower and Jerusalem artichoke. Many garden flowers are also in group, such as Coreopsis, Cosmos, Echinacea, Rudbeckia. Some authors place Coreopsis and Cosmos in the Coreopsideae tribe, in addition to the benefits brought by the group, some are also problematic weeds. Species of Ambrosia produce large quantities of pollen, each plant is reputed to be able to produce about a billion grains of pollen over a season, and the plant is wind-pollinated. It is highly allergenic, as the greatest pollen allergen of all pollens, the traditional circumscription of the Heliantheae arises from Cassinis 19th-century classification of the Asteraceae. Such classifications may define a supertribe Helianthodae including these smaller tribes, the Eupatorieae, a Revision of the Tribal and Subtribal Limits of the Heliantheae. Strother, John L.

Carl Linnaeus
–
Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist, who formalised the modern system of naming organisms called binomial nomenclature. He is known by the father of modern taxonomy. Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus, Linnaeus was born in the countryside of Småland, in southern Sweden. He received most of his education at Uppsala University. He lived abroad between 1735 and 1738, where he studied and also published a first edition of his Systema Naturae in the Netherlands and he then returned to Sweden, where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on journeys through Sweden to find and classify plants. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, at the time of his death, he was one of the most acclaimed scientists in Europe. The philosopher Jean-Jacques Rousseau sent him the message, Tell him I know no man on earth. The German writer Johann Wolfgang von Goethe wrote, With the exception of Shakespeare and Spinoza, Swedish author August Strindberg wrote, Linnaeus was in reality a poet who happened to become a naturalist. Among other compliments, Linnaeus has been called Princeps botanicorum, The Pliny of the North and he is also considered as one of the founders of modern ecology. In botany, the abbreviation used to indicate Linnaeus as the authority for species names is L. In older publications, sometimes the abbreviation Linn. is found, Linnæus was born in the village of Råshult in Småland, Sweden, on 23 May 1707. He was the first child of Nicolaus Ingemarsson and Christina Brodersonia and his siblings were Anna Maria Linnæa, Sofia Juliana Linnæa, Samuel Linnæus, and Emerentia Linnæa. One of a line of peasants and priests, Nils was an amateur botanist, a Lutheran minister. Christina was the daughter of the rector of Stenbrohult, Samuel Brodersonius, a year after Linnæus birth, his grandfather Samuel Brodersonius died, and his father Nils became the rector of Stenbrohult. The family moved into the rectory from the curates house, even in his early years, Linnæus seemed to have a liking for plants, flowers in particular. Whenever he was upset, he was given a flower, which calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus, soon Linnæus was given his own patch of earth where he could grow plants

Synonym (taxonomy)
–
For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use, it is now a synonym of the current scientific name which is Picea abies, unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms are not equals, but have a different status, for any taxon with a particular circumscription, position, and rank, only one scientific name is considered to be the correct one at any given time. A synonym cannot exist in isolation, it is always an alternative to a different scientific name, given that the correct name of a taxon depends on the taxonomic viewpoint used a name that is one taxonomists synonym may be another taxonomists correct name. Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to one, a species is moved to a different genus. To the general user of scientific names, in such as agriculture, horticulture, ecology, general science. A synonym is a name that was used as the correct scientific name but which has been displaced by another scientific name. Thus Oxford Dictionaries Online defines the term as a name which has the same application as another. In handbooks and general texts, it is useful to have mentioned as such after the current scientific name. Synonyms used in this way may not always meet the strict definitions of the synonym in the formal rules of nomenclature which govern scientific names. Changes of scientific name have two causes, they may be taxonomic or nomenclatural, a name change may be caused by changes in the circumscription, position or rank of a taxon, representing a change in taxonomic, scientific insight. A name change may be due to purely nomenclatural reasons, that is, based on the rules of nomenclature, the earliest such name is called the senior synonym, while the later name is the junior synonym. One basic principle of zoological nomenclature is that the earliest correctly published name, synonyms are important because if the earliest name cannot be used, then the next available junior synonym must be used for the taxon. Objective synonyms refer to taxa with the type and same rank. For example, John Edward Gray published the name Antilocapra anteflexa in 1855 for a species of pronghorn, however, it is now commonly accepted that his specimen was an unusual individual of the species Antilocapra americana published by George Ord in 1815. Ords name thus takes precedence, with Antilocapra anteflexa being a subjective synonym. Objective synonyms are common at the level of genera, because for various reasons two genera may contain the type species, these are objective synonyms

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Genus
–
A genus is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of classification, genus comes above species. In binomial nomenclature, the name forms the first part of the binomial species name for each species within the genus. Felis catus and Felis silvestris are two species within the genus Felis, Felis is a genus within the family Felidae. The composition of a genus is determined by a taxonomist, the standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. Moreover, genera should be composed of units of the same kind as other genera. The term comes from the Latin genus, a noun form cognate with gignere, linnaeus popularized its use in his 1753 Species Plantarum, but the French botanist Joseph Pitton de Tournefort is considered the founder of the modern concept of genera. The scientific name of a genus may be called the name or generic epithet. It plays a role in binomial nomenclature, the system of naming organisms. The rules for the names of organisms are laid down in the Nomenclature Codes. The standard way of scientifically describing species and other lower-ranked taxa is by binomial nomenclature, the generic name forms its first half. For example, the gray wolfs binomial name is Canis lupus, with Canis being the name shared by the wolfs close relatives. The specific name is written in lower-case and may be followed by names in zoology or a variety of infraspecific names in botany. Especially with these names, when the generic name is known from context. Because animals are typically only grouped within subspecies, it is written as a trinomen with a third name. Dog breeds, meanwhile, are not scientifically distinguished, there are several divisions of plant species and therefore their infraspecific names generally include contractions explaining the relation. For example, the genus Hibiscus includes hundreds of other species apart from the Rose of Sharon or common garden hibiscus, Rose of Sharon doesnt have subspecies but has cultivars that carry desired traits, such as the bright white H. syriaca Diana. Hawaiian hibiscus, meanwhile, includes several separate species, since not all botanists agree on the divisions or names between species, it is common to specify the source of the name using author abbreviations

Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

South America

South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It may also be considered a subcontinent of the Americas, which is the used in nations that speak Romance languages. The reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean, North America and it includes twelve sovereign states, a part of France, and a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands, Trinidad and Tobago, South America has an area of 17,840,000 square kilometers. Its population as of 2005 has been estimated at more than 371,090,000, South America ranks fourth in area and fifth in population. Brazil is by far the most populous South American country, with more than half of the population, followed by Colombia, Argentina, Venezuela. In recent decades Brazil has also concentrated half of the regions GDP and has become a first regional power, most of the population lives near the continents western or eastern coasts while the interior and the far south are sparsely populated. Most of the continent lies in the tropics, the continents cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the majority of South Americans speak Portuguese or Spanish. South America occupies the portion of the Americas. The continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border. Almost all of mainland South America sits on the South American Plate, South Americas major mineral resources are gold, silver, copper, iron ore, tin, and petroleum. These resources found in South America have brought high income to its countries especially in times of war or of rapid growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity often has hindered the development of diversified economies and this is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export. South America is one of the most biodiverse continents on earth, South America is home to many interesting and unique species of animals including the llama, anaconda, piranha, jaguar, vicuña, and tapir. The Amazon rainforests possess high biodiversity, containing a proportion of the Earths species. Brazil is the largest country in South America, encompassing around half of the land area

North America

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16. 5% of the land area. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7. 5% of the worlds population, North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago, the Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the migrations and the arrival of European settlers during the Age of Discovery. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants, European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French, the Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a map, in which he placed the word America on the continent of South America. He explained the rationale for the name in the accompanying book Cosmographiae Introductio, for Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespuccis name, but in its feminine form America, following the examples of Europa, Asia and Africa. Later, other mapmakers extended the name America to the continent, In 1538. Some argue that the convention is to use the surname for naming discoveries except in the case of royalty, a minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of Amairick. Another is that the name is rooted in a Native American language, the term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States, alternatively, usage sometimes includes Greenland and Mexico, as well as offshore islands

Jerusalem artichoke
–
It is also cultivated widely across the temperate zone for its tuber, which is used as a root vegetable. Helianthus tuberosus is a perennial plant growing to 1. 5–3 m tall with opposite leaves on the upper part of the stem. The leaves have a rough, hairy texture, larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm long. Leaves higher on the stem are smaller and narrower, the flowers are yellow and produced in capitate flowerheads, which are 5–10 cm in diameter, with 10–20 ray florets and 60 or more small disc florets. The tubers are elongated and uneven, typically 7. 5–10 cm long and 3–5 cm thick and they vary in colour from pale brown to white, red, or purple. Before the arrival of Europeans, Native Americans cultivated Helianthus tuberosus as a food source, the tubers persist for years after being planted, so that the species expanded its range from central North America to the eastern and western regions. Early European colonists learned of this, and sent tubers back to Europe and it later gradually fell into obscurity in North America, but attempts to market it commercially have been successful in the late 1900s and early 2000s. The artichoke contains about 2% protein, no oil, and a lack of starch. It is rich in the carbohydrate inulin, which is a polymer of the monosaccharide fructose, tubers stored for any length of time will convert their inulin into its component fructose. Jerusalem artichokes have a sweet taste because of the fructose, which is about one. It has also reported as a folk remedy for diabetes. Temperature variances have been shown to affect the amount of inulin the Jerusalem artichoke can produce, when not in tropical regions, it has been shown to make less inulin than when it is in a warmer region. Despite its name, the Jerusalem artichoke has no relation to Jerusalem, the origin of the Jerusalem part of the name is uncertain. Italian settlers in the United States called the plant girasole, the Italian word for sunflower, over time, the name girasole may have been changed to Jerusalem. The English later corrupted girasole artichoke to Jerusalem artichoke, another explanation for the name is that the Puritans, when they came to the New World, named the plant with regard to the New Jerusalem they believed they were creating in the wilderness. There have also been other names applied to the plant, such as the French or Canada potato, topinambour. Sunchoke, a name by which it is known today, was invented in the 1960s by Frieda Caplan. The artichoke part of the Jerusalem artichokes name comes from the taste of its edible tuber, Samuel de Champlain, the French explorer, sent the first samples of the plant to France, noting its taste was similar to that of an artichoke

Temperateness
–
In geography, temperate or tepid latitudes of Earth lie between the tropics and the polar regions. The temperatures in these regions are relatively moderate, rather than extremely hot or cold. The north temperate zone extends from the Tropic of Cancer to the Arctic Circle, the south temperate zone extends from the Tropic of Capricorn to the Antarctic Circle. In some climate classifications, the zone is often divided into several smaller climate zones. These include Humid subtropical climate, Mediterranean climate, oceanic, subtropical climates are located between 23. 5° and 35. 0° north or south latitude on the eastern or leeward sides of landmasses. This climate has long, generally hot, summers and short, mild winters and these climates may occur in southern Asia, the southeastern United States, parts of eastern Australia, and in eastern coastal South America. Mediterranean climates, occur between 30° and 42° north and south latitude, on the sides of landmasses. This climate has hot summers and short mild winters, however, seasonal rainfall is the opposite of that of the subtropical humid type. These climates occur near the rimlands of the Mediterranean Sea, in western Australia, in California, the oceanic climates occur in the higher middle latitudes, between 45° and 60° north and south latitude. They are created by the flow from the cool high latitude oceans to their west. This causes the climate to have cool summers and cool winters, annual rainfall is spread throughout the entire year. Regions with this climate include Western Europe, northwestern North America, the Continental climates occur in middle latitudes, between 35° or 40° to 55°. These climates are normally inland or on sides of landmasses. They feature warm to hot summers and cold winters, with a large temperature variation. Regions with this climate include northern temperate Asia, the northern United States, southern Canada, the vast majority of the worlds human population resides in temperate zones, especially in the northern hemisphere, due to its greater mass of land. The richest temperate flora in the world is found in southern Africa, geographical zone Habitat Köppen climate classification Middle latitudes Polar circle Subtropics

U.S. Fish and Wildlife Service
–
The United States Fish and Wildlife Service is an agency of the federal government within the U. S. Department of the Interior dedicated to the management of fish, wildlife, and natural habitats. The mission of the agency is working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people. The leader of the FWS is the director of the U. S. Fish and Wildlife Service Daniel M. Ashe, of Maryland, bavin National Fish and Wildlife Forensic Laboratory Landscape Conservation Cooperatives The vast majority of fish and wildlife habitat is on non-federal lands. The FWS employs approximately 9,000 people and is organized into an administrative office, eight regional offices. Spencer Fullerton Baird was appointed its first commissioner, in 1903, the Fish Commission was reorganized as the United States Bureau of Fisheries. In 1885–1886, the Division of Economic Ornithology and Mammalogy was established within the United States Department of Agriculture, in 1896 it became the Division of Biological Survey. Its early work focused on the effect of birds in controlling pests and mapping the geographical distribution of plants. Clinton Hart Merriam headed the Bureau for 25 years and became a figure for improving the scientific understanding of birds. Under Darlings guidance, the Bureau began a legacy of protecting vital natural habitat throughout the country. The USFWS was finally created in 1940, when the Bureaus of Fisheries, however, these exceptions often only apply to Native Americans that are registered with the federal government and are enrolled with a federally recognized tribe. Therefore, many people that wish to practice their religion continue to face persecution. This has become a source of conflict between many tribes and the US Fish and Wildlife Service. In the late 1990s and early 2000s, the USFWS began to incorporate the research of scientists into conservation decisions. Additionally, other natural resource agencies within the United States government, such as the USDA, have taken steps to be inclusive of tribes, native people. This has marked a transition to a relationship of more cooperation rather than the tension between tribes and government agencies seen historically, today, these agencies work closely with tribal governments to ensure the best conservation decisions are made and that tribes retain their sovereignty

Endangered Species Act
–
The U. S. Supreme Court found that the plain intent of Congress in enacting the ESA was to halt and reverse the trend toward species extinction, whatever the cost. The Act is administered by two agencies, the United States Fish and Wildlife Service and the National Oceanic and Atmospheric Administration. Experimental, nonessential populations of endangered species are treated as threatened species on land, for consultation purposes. The near-extinction of the bison and the disappearance of the passenger pigeon helped drive the call for wildlife conservation starting in the 1900s, the public was introduced to a new concept, extinction. Market hunting for the trade and for the table was one aspect of the problem. The early naturalists also killed birds and other wildlife for study, personal curio collections, while habitat losses continued as communities and farmland grew, the widespread use of pesticides and the introduction of non-native species also affected wildlife. One species in particular received widespread attention—the whooping crane, the species historical range extended from central Canada South to Mexico, and from Utah to the Atlantic coast. It would be eight years before the first national law regulating wildlife commerce was signed. The whooping crane population by 1941 was estimated at about only 16 birds still in the wild, the Lacey Act of 1900 was the first federal law that regulated commercial animal markets. It prohibited interstate commerce of animals killed in violation of state game laws, other legislation followed, including the Migratory Bird Conservation Act of 1929, a 1937 treaty prohibiting the hunting of right and gray whales, and the Bald Eagle Protection Act of 1940. These later laws had a low cost to society–the species were relatively little opposition was raised. Whereas the Lacey Act dealt with game management and market commerce species. The predecessor of the ESA was the Endangered Species Preservation Act of 1966, passed by Congress, this act permitted the listing of native U. S. animal species as endangered and for limited protections upon those animals. It also directed federal agencies to preserve habitat on their lands. The Act also consolidated and even expanded authority for the Secretary of the Interior to manage, other public agencies were encouraged, but not required, to protect species. The act did not address the commerce in endangered species and parts, in March,1967 the first list of endangered species was issued under the act. It included 14 mammals,36 birds,6 reptiles and amphibians and 22 fish and it included only vertebrates because the Department of Interiors definition of fish and wildlife was limited to vertebrates. However, with time, researchers noticed that the animals on the species list still were not getting enough protection

Silviculture
–
Silviculture is the practice of controlling the establishment, growth, composition, health, and quality of forests to meet diverse needs and values. The name comes from the Latin silvi- + culture, the study of forests and woods is termed silvology. Silviculture also focuses on making sure that the treatment of forest stands are used to preserve, more particularly, silviculture is the theory and practice of controlling the establishment, composition, constitution, and growth of forests. Suggestions for how best to go about the job, presented by Jeglum et al. though aimed primarily at the boreal forest in Ontario, the 110-page publication describes Best Management Practices, first by general principles, then by sensitive sites. Illustrations are plentiful and are chosen to complement this excellent text. To some the distinction between forestry and silviculture is that silviculture is applied at the level and forestry is broader. For example, John D. Matthews says complete regimes for regenerating, tending, adaptive management is common in silviculture, whereas forestry can include natural, conserved land without a stand level management and treatment being applied. A common taxonomy divides silviculture into regenerating, tending and harvesting techniques, and Dauerwald - Continuous cover forestry, in which are found, un-even aged forestry - Plenterwald - Selection forest - Zielstärkennutzung - Target diameter harvesting. This misunderstanding has meant that many older English textbooks did not capture the complexity of silviculture as practiced where it originated in Mitteleuropa. This silviculture was culturally predicated on wood production in temperate and boreal climates, the misapplication of this philosophy to those tropical forests has been problematic. There is also an alternative silvicultural tradition which developed in Japan, after harvesting comes regeneration, which may be split into Natural and Artificial. And tending which includes release treatments, pruning, thinning and intermediate treatments, as it can be imagined it maybe that any of these 3 phases may happen at the same time, within a stand, depending on the goal for that particular stand. Regeneration is basic to the continuation of forested, as well as to the afforestation of treeless land, regeneration can take place through self-sown seed, by artificially sown seed, or by planted seedlings. In whichever case, the performance of regeneration depends on its growth potential, seed, of course, is needed for all regeneration modes, both for natural or artificial sowing and for raising planting stock in a nursery. The process of natural regeneration involves the renewal of forests by means of self-sown seeds, root suckers, in natural forests, conifers rely almost entirely on regeneration through seed. Most of the broadleaves, however, are able to regenerate by the means of emergence of shoots from stumps, any seed, self-sown or artificially applied, requires a seedbed suitable for securing germination. In order to germinate, a seed requires suitable conditions of temperature, moisture, white spruce seed germinated at 35 °F and 40 °F after continuous stratification for one year or longer and developed radicles <6 cm long in the cold room. When exposed to light, those germinants developed chlorophyll and were normally phototropic with continued elongation, shade is very important to the survival of young seedlings

Plantation
–
A plantation is an area of land or water where one crop is specifically planted for widespread commercial sale. The crops grown include cotton, coffee, tea, cocoa, sugar cane, sisal, oil seeds, oil palms, rubber trees, protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations were located. Among the earliest examples of plantations were the latifundia of the Roman Empire, Plantation agriculture grew rapidly with the increase in international trade and the development of a worldwide economy that followed the expansion of European colonial empires. Like every economic activity, it has changed over time, Industrial plantations are established to produce a high volume of wood in a short period of time. Plantations are grown by state forestry authorities and/or the paper and wood industries, christmas trees are often grown on plantations as well. In southern and southeastern Asia, teak plantations have replaced the natural forest. Industrial plantations are managed for the commercial production of forest products. Individual blocks are usually even-aged and often consist of just one or two species and these species can be exotic or indigenous. Forest genetic resources are the basis for genetic alteration, selected individuals grown in seed orchards are a good source for seeds to develop adequate planting material. Wood production on a plantation is generally higher than that of natural forests. In 2000, while plantations accounted for 5% of global forest, in the first year, the ground is prepared usually by the combination of burning, herbicide spraying, and/or cultivation and then saplings are planted by human crew or by machine. The saplings are usually obtained in bulk from industrial nurseries, which may specialize in breeding in order to produce fast growing disease-. In the first few years until the canopy closes, the saplings are looked after, after the canopy closes, with the tree crowns touching each other, the plantation is becoming dense and crowded, and tree growth is slowing due to competition. This stage is termed pole stage, when competition becomes too intense, it is time to thin out the section. There are several methods for thinning, but where topography permits, the most popular is row-thinning, many trees are removed, leaving regular clear lanes through the section so that the remaining trees have room to expand again. The removed trees are delimbed, forwarded to the forest road, loaded onto trucks, a typical pole stage plantation tree is 7–30 cm in diameter at breast height. Such trees are not suitable for timber, but are used as pulp for paper and particleboard. As the trees grow and become dense and crowded again, the process is repeated

North Carolina

North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, North Carolina is the 28th most extensive and the 9th most populous of the U. S. states. The state is divided into 100 counties, the most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City. The state has a range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell. The climate of the plains is strongly influenced by the Atlantic Ocean. Most of the falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a highland climate. North Carolina is bordered by South Carolina on the south, Georgia on the southwest, Tennessee on the west, Virginia on the north, the United States Census Bureau places North Carolina in the South Atlantic division of the southern region. So many ships have been lost off Cape Hatteras that the area is known as the Graveyard of the Atlantic, the most famous of these is the Queen Annes Revenge, which went aground in Beaufort Inlet in 1718. The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, the Piedmont region of central North Carolina is the states most populous region, containing the six largest cities in the state by population. It consists of rolling countryside frequently broken by hills or low mountain ridges. The Piedmont ranges from about 300 feet in elevation in the east to about 1,500 feet in the west, the western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, the Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet, the highest point east of the Mississippi River. North Carolina has 17 major river basins, the five basins west of the Blue Ridge Mountains flow to the Gulf of Mexico, while the remainder flow to the Atlantic Ocean. Of the 17 basins,11 originate within the state of North Carolina, but only four are contained entirely within the states border – the Cape Fear, the Neuse, the White Oak, and the Tar-Pamlico basin. Elevation above sea level is most responsible for temperature change across the state, the climate is also influenced by the Atlantic Ocean and the Gulf Stream, especially in the coastal plain. These influences tend to cause warmer winter temperatures along the coast, the coastal plain averages around 1 inch of snow or ice annually, and in many years, there may be no snow or ice at all. North Carolina experiences severe weather in summer and winter, with summer bringing threat of hurricanes, tropical storms, heavy rain

Annual plant
–
An annual plant is a plant that completes its life cycle, from germination to the production of seed, within one year, and then dies. Summer annuals germinate during spring or early summer and mature by autumn of the same year, winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual can occur in as little as a month in some species, oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is used in classrooms for education. Many desert annuals are therophytes, because their life cycle is only weeks. In cultivation, many plants are, or are grown as, annuals. Some perennials and biennials are grown in gardens as annuals for convenience, carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively. Tomato, sweet potato and bell pepper are tender perennials usually grown as annuals, ornamental perennials commonly grown as annuals are impatiens, wax begonia, snapdragon, Pelargonium, coleus and petunia. Examples of true annuals include corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia, summer annuals sprout, flower, produce seed, and die, during the warmer months of the year. The lawn weed crabgrass is a summer annual, winter annuals germinate in autumn or winter, live through the winter, then bloom in winter or spring. The plants grow and bloom during the season when most other plants are dormant or other annuals are in seed form waiting for warmer weather to germinate. Winter annuals die after flowering and setting seed, the seeds germinate in the autumn or winter when the soil temperature is cool. Winter annuals typically grow low to the ground, where they are sheltered from the coldest nights by snow cover. Some common winter annuals include henbit, deadnettle, chickweed, ironically, the property that they prevent the soil from drying out can also be problematic for commercial agriculture. In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to the conversion into a perennial plant, researchers deactivated the SOC1 and FUL genes in Arabidopsis thaliana, which control flowering time. This switch established phenotypes common in plants, such as wood formation

Pseudanthium
–
The individual flowers of a pseudanthium commonly are called florets. The real flowers are small and often greatly reduced. Pseudanthia are characteristic of the daisy and sunflower family, whose flowers are differentiated into ray flowers and disk flowers, the disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorphic and the corolla has one large lobe, either ray or disk flowers may be absent in some plants, Senecio vulgaris lacks ray flowers and Taraxacum officinale lacks disk flowers. The pseudanthium has a whorl of bracts below the flowers, forming an involucre, in all cases, a pseudanthium is superficially indistinguishable from a flower, but closer inspection of its anatomy will reveal that it is composed of multiple flowers. Head This is an equivalent term for head and pseudanthium when used in the botanical sense. Capitulum Capitulum can be used as a synonym for pseudanthium and flower head, however its use is generally. At least one source defines it as a flower head. In addition to its use as a term meaning flower head it is also used to mean the top of the sphagnum plant. Calathid This is a rarely used term. It was defined in the 1966 book, The genera of flowering plants, however, on-line botanical glossaries do not define it and Google Scholar does not link to any significant usage of the term in a botanical sense. Possible pseudanthia of this type may occur in the following families, Hydatellaceae Lemnaceae Pandanaceae Triuridaceae Phyllanthaceae

Cultivars
–
The term cultivar most commonly refers to an assemblage of plants selected for desirable characteristics that are maintained during propagation. More generally, cultivar refers to the most basic classification category of cultivated plants governed by the ICNCP, most cultivars have arisen in cultivation, but a few are special selections from the wild. Popular ornamental garden plants like roses, camellias, daffodils, rhododendrons, trees used in forestry are also special selections grown for their enhanced quality and yield of timber. Cultivars form a part of Liberty Hyde Baileys broader grouping. Cultivar was coined by Bailey and it is regarded as a portmanteau of cultivated and variety. A cultivar is not the same as a variety, a taxonomic rank below subspecies. In recent times, the naming of cultivars has been complicated by the use of statutory plant patents, the International Union for the Protection of New Varieties of Plants offers legal protection of plant cultivars to people or organisations who introduce new cultivars to commerce. UPOV requires that a cultivar be distinct, uniform and stable, to be distinct, it must have characteristics that easily distinguish it from any other known cultivar. To be uniform and stable, the cultivar must retain these characteristics under repeated propagation, a cultivar is given a cultivar name, which consists of the scientific Latin botanical name followed by a cultivar epithet. The cultivar epithet is usually in a vernacular language, for example, the full cultivar name of the King Edward potato is Solanum tuberosum King Edward. The King Edward part of the name is the cultivar epithet, the origin of the term cultivar arises from the need to distinguish between wild plants and those with characteristics that have arisen in cultivation. This distinction dates back to the Greek philosopher Theophrastus, the Father of Botany, botanical historian Alan Morton notes that Theophrastus in his Enquiry into Plants had an inkling of the limits of culturally induced changes and of the importance of genetic constitution. In Species Plantarum, Linnaeus listed all the known to him. Most of the listed by Linnaeus were of garden origin rather than being wild plants. Over time there was an increasing need to distinguish between plants growing in the wild, and those with variations that had produced in cultivation. In the nineteenth century many garden-derived plants were given names, sometimes in Latin. In the twentieth century an improved international terminology was proposed for the classification and it is essentially the equivalent of the botanical variety except in respect to its origin. However, Bailey was never explicit about the etymology of the word, and it has suggested that it is a contraction of the words cultigen and variety

Plant stem
–
A stem is one of two main structural axes of a vascular plant, the other being the root. The stem is divided into nodes and internodes, The nodes hold one or more leaves. Adventitious roots may also be produced from the nodes, the internodes distance one node from another. The term shoots is often confused with stems, shoots generally refers to new plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the surface but some plants have underground stems. Stems have four main functions which are, Support for and the elevation of leaves, flowers, the stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits. Transport of fluids between the roots and the shoots in the xylem and phloem Storage of nutrients Production of new living tissue, the normal lifespan of plant cells is one to three years. Stems have cells called meristems that annually generate new living tissue, Stems are often specialized for storage, asexual reproduction, protection or photosynthesis, including the following, Acaulescent – used to describe stems in plants that appear to be stemless. Actually these stems are just extremely short, the leaves appearing to rise out of the ground. Arborescent – tree like with woody stems normally with a single trunk, branched – aerial stems are described as being branched or unbranched Bud – an embryonic shoot with immature stem tip. Bulb – a short underground stem with fleshy storage leaves attached, e. g. onion, daffodil. Bulbs often function in reproduction by splitting to form new bulbs or producing small new bulbs termed bulblets, bulbs are a combination of stem and leaves so may better be considered as leaves because the leaves make up the greater part. Caespitose – when stems grow in a mass or clump or in low growing mats. Cladode – a flattened stem that appears more-or-less leaf like and is specialized for photosynthesis, climbing – stems that cling or wrap around other plants or structures. Corm – a short enlarged underground, storage stem, e. g. taro, decumbent – stems that lie flat on the ground and turn upwards at the ends. Fruticose – stems that grow shrublike with woody like habit, herbaceous – non woody, they die at the end of the growing season. Pedicel – stems that serve as the stalk of a flower in an inflorescence or infrutescence. Peduncle – a stem that supports an inflorescence Prickle – a sharpened extension of the outer layers

Petiole (botany)
–
In botany, the petiole is the stalk that attaches the leaf blade to the stem. The petiole is the transition between the stem and the leaf blade, outgrowths appearing on each side of the petiole in some species are called stipules. Leaves lacking a petiole are called sessile or epetiolate, the petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the stalk may be long, as in the leaves of celery and rhubarb, short or completely absent. Subpetiolate leaves are petiolate, or have an extremely short petiole. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile, in some other plant groups, such as the speedwell genus Veronica, petiolate and sessile leaves may occur in different species. In the grasses the leaves are apetiolate, but the blade may be narrowed at the junction with the leaf sheath to form a pseudopetiole. In plants with leaves, the leaflets are attached to a continuation of the petiole called the rachis. Each leaflet may be attached to the rachis by a stalk called the petiolule. There may be swollen regions at either end of the known as pulvina that are composed of a flexible tissue that allows leaf movement. Pulvina are common in the bean family Fabaceae and the plant family Marantaceae. A pulvinus on a petiolule is called a pulvinulus, in some plants, the petioles are flattened and widened, to become phyllodes or phyllodia, or cladophylls and the true leaves may be reduced or absent. Thus, the comes to serve the functions of the leaf. Phyllodes are common in the genus Acacia, especially the Australian species, in Acacia koa, the phyllodes are leathery and thick, allowing the tree to survive stressful environments. The petiole allows partially submerged hydrophytes to have leaves floating at different depths, in plants such as rhubarb, celery, artichokes and cardoons the petioles are cultivated as edible crops. The petiole of rhubarb grows directly from the rhizome and produces the leaf at its end, botanically it is categorized as a vegetable and culinarily used as a fruit. Petiole is pronounced /ˈpiːtᵻoʊl/ and comes from Latin petiolus, or peciolus little foot, stem, the regular diminutive pediculus is also used for foot stalk

Leaf
–
A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot, Leaves are collectively referred to as foliage, as in autumn foliage. Although leaves can be seen in different shapes, sizes and textures, typically a leaf is a thin, dorsiventrally flattened organ, borne above ground. Most leaves have distinctive upper surface and lower surface that differ in colour, hairiness, broad, flat leaves with complex venation are known as megaphylls and the species that bear them, the majority, as broad-leaved or megaphyllous plants. In others, such as the clubmosses, with different evolutionary origins, some leaves, such as bulb scales are not above ground, and in many aquatic species the leaves are submerged in water. Succulent plants often have thick juicy leaves, but some leaves are without major photosynthetic function and may be dead at maturity, as in some cataphylls, furthermore, several kinds of leaf-like structures found in vascular plants are not totally homologous with them. Examples include flattened plant stems called phylloclades and cladodes, and flattened leaf stems called phyllodes which differ from both in their structure and origin. Many structures of plants, such as the phyllids of mosses and liverworts and even of some foliose lichens. Leaves are the most important organs of most vascular plants and these are then further processed by chemical synthesis into more complex organic molecules such as cellulose, the basic structural material in plant cell walls. The plant must therefore bring these three together in the leaf for photosynthesis to take place. Once sugar has been synthesized, it needs to be transported to areas of growth such as the plant shoots and roots. Vascular plants transport sucrose in a tissue called the phloem. The phloem and xylem are parallel to each other but the transport of materials is usually in opposite directions. Within the leaf these vascular systems branch to form veins which supply as much as the leaf as possible and they are arranged on the plant so as to expose their surfaces to light as efficiently as possible without shading each other, but there are many exceptions and complications. For instance plants adapted to windy conditions may have pendent leaves, such as in many willows, the flat, or laminar, shape also maximises thermal contact with the surrounding air, promoting cooling. Functionally, in addition to photosynthesis the leaf is the site of transpiration and guttation. Many gymnosperms have thin needle-like or scale-like leaves that can be advantageous in cold climates with frequent snow and these are interpreted as reduced from megaphyllous leaves of their Devonian ancestors. For xerophytes the major constraint is not light flux or intensity, some window plants such as Fenestraria species and some Haworthia species such as Haworthia tesselata and Haworthia truncata are examples of xerophytes. and Bulbine mesembryanthemoides

Fibonacci numbers
–
The Fibonacci sequence is named after Italian mathematician Leonardo of Pisa, known as Fibonacci. His 1202 book Liber Abaci introduced the sequence to Western European mathematics, the sequence described in Liber Abaci began with F1 =1. Fibonacci numbers are related to Lucas numbers L n in that they form a complementary pair of Lucas sequences U n = F n and V n = L n. They are intimately connected with the ratio, for example. Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is a journal dedicated to their study. The Fibonacci sequence appears in Indian mathematics, in connection with Sanskrit prosody, in the Sanskrit tradition of prosody, there was interest in enumerating all patterns of long syllables that are 2 units of duration, and short syllables that are 1 unit of duration. Counting the different patterns of L and S of a given duration results in the Fibonacci numbers, susantha Goonatilake writes that the development of the Fibonacci sequence is attributed in part to Pingala, later being associated with Virahanka, Gopāla, and Hemachandra. He dates Pingala before 450 BC, however, the clearest exposition of the sequence arises in the work of Virahanka, whose own work is lost, but is available in a quotation by Gopala, Variations of two earlier meters. For example, for four, variations of meters of two three being mixed, five happens, in this way, the process should be followed in all mātrā-vṛttas. The sequence is also discussed by Gopala and by the Jain scholar Hemachandra, outside India, the Fibonacci sequence first appears in the book Liber Abaci by Fibonacci. The puzzle that Fibonacci posed was, how many pairs will there be in one year, at the end of the first month, they mate, but there is still only 1 pair. At the end of the month the female produces a new pair. At the end of the month, the original female produces a second pair. At the end of the month, the original female has produced yet another new pair. At the end of the nth month, the number of pairs of rabbits is equal to the number of new pairs plus the number of pairs alive last month and this is the nth Fibonacci number. The name Fibonacci sequence was first used by the 19th-century number theorist Édouard Lucas, the most common such problem is that of counting the number of compositions of 1s and 2s that sum to a given total n, there are Fn+1 ways to do this. For example, if n =5, then Fn+1 = F6 =8 counts the eight compositions, 1+1+1+1+1 = 1+1+1+2 = 1+1+2+1 = 1+2+1+1 = 2+1+1+1 = 2+2+1 = 2+1+2 = 1+2+2, all of which sum to 5. The Fibonacci numbers can be found in different ways among the set of strings, or equivalently

It measures approximately 137.5077640500378546463487. ° A096627 or in radians 2.39996322972865332. The golden ratio is equal to φ = a/b given the conditions above, let ƒ be the fraction of the circumference subtended by the golden angle, or equivalently, the golden angle divided by the angular measurement of the circle. But since 1 + φ = φ2, it follows that f =1 φ2 This is equivalent to saying that φ2 golden angles can fit in a circle, the fraction of a circle occupied by the golden angle is therefore f ≈0.381966. The golden angle g can therefore be numerically approximated in degrees as, g ≈360 ×0.381966 ≈137.508 ∘, or in radians as, g ≈2 π ×0.381966 ≈2.39996. The golden angle plays a significant role in the theory of phyllotaxis, for example, the golden angle is the angle separating the florets on a sunflower

Larva
–
A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a phase of their life cycle. The larvas appearance is very different from the adult form. A larva often has unique structures and organs that do not occur in the adult form and their diet may also be considerably different. Larvae are frequently adapted to separate from adults. For example, some such as tadpoles live almost exclusively in aquatic environments. By living in an environment, larvae may be given shelter from predators. Animals in the stage will consume food to fuel their transition into the adult form. In some species like barnacles, adults are immobile but their larvae are mobile, some larvae are dependent on adults to feed them. In many eusocial Hymenoptera species, the larvae are fed by female workers, in Ropalidia marginata the males are also capable of feeding larvae but they are much less efficient, spending more time and getting less food to the larvae. The larvae of species can become pubescent and do not develop further into the adult form. This is a type of neoteny and it is a misunderstanding that the larval form always reflects the groups evolutionary history. This could be the case, but often the stage has evolved secondarily. In these cases the form may differ more than the adult form from the groups common origin. Within Insects, only Endopterygotes show different types of larvae, several classifications have been suggested by many entomologists, and following classification is based on Antonio Berlese classification in 1913. There are four types of endopterygote larvae types, Apodous larvae - no legs at all and are poorly sclerotized. Based on sclerotization, three forms are recognized. Eucephalous - with well sclerotized head capsule, found in Nematocera, Buprestidae and Cerambycidae families

Florida /ˈflɒrᵻdə/ is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States, the Miami metropolitan area is Floridas most populous urban area. The city of Tallahassee is the state capital, much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south, the American alligator, American crocodile, Florida panther, and manatee can be found in the Everglades National Park. It was a location of the Seminole Wars against the Native Americans. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, the states economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, the Kennedy Space Center, Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing, by the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee, the Timucua, the Ais, the Tocobaga, the Calusa and the Tequesta. Florida was the first part of the continental United States to be visited and settled by Europeans, the earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2,1513 and he named the region La Florida. The story that he was searching for the Fountain of Youth is a myth, in May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a wall of red mangroves spread mile after mile, some reaching as high as 70 feet. Very soon, many smokes appeared along the whole coast, billowing against the sky, the Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida. Both the Spanish and French established settlements in Florida, with varying degrees of success, in 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561. Spain maintained tenuous control over the region by converting the tribes to Christianity. The area of Spanish Florida diminished with the establishment of English settlements to the north, the English attacked St. Augustine, burning the city and its cathedral to the ground several times. Florida attracted numerous Africans and African-Americans from adjacent British colonies who sought freedom from slavery, in 1738, Governor Manuel de Montiano established Fort Gracia Real de Santa Teresa de Mose near St

Georgia is a state in the southeastern United States. It was established in 1733, the last of the original Thirteen Colonies, named after King George II of Great Britain, Georgia was the fourth state to ratify the United States Constitution, on January 2,1788. It declared its secession from the Union on January 19,1861 and it was the last state to be restored to the Union, on July 15,1870. Georgia is the 24th largest and the 8th most populous of the 50 United States, from 2007 to 2008,14 of Georgias counties ranked among the nations 100 fastest-growing, second only to Texas. Georgia is known as the Peach State and the Empire State of the South, Atlanta is the states capital, its most populous city and has been named a global city. Georgia is bordered to the south by Florida, to the east by the Atlantic Ocean and South Carolina, to the west by Alabama, the states northern part is in the Blue Ridge Mountains, part of the Appalachian Mountains system. Georgias highest point is Brasstown Bald at 4,784 feet above sea level, Georgia is the largest state entirely east of the Mississippi River in land area. Before settlement by Europeans, Georgia was inhabited by the mound building cultures, the British colony of Georgia was founded by James Oglethorpe on February 12,1733. The colony was administered by the Trustees for the Establishment of the Colony of Georgia in America under a charter issued by King George II. The Trustees implemented a plan for the colonys settlement, known as the Oglethorpe Plan. In 1742 the colony was invaded by the Spanish during the War of Jenkins Ear, in 1752, after the government failed to renew subsidies that had helped support the colony, the Trustees turned over control to the crown. Georgia became a colony, with a governor appointed by the king. The Province of Georgia was one of the Thirteen Colonies that revolted against British rule in the American Revolution by signing the 1776 Declaration of Independence, the State of Georgias first constitution was ratified in February 1777. Georgia was the 10th state to ratify the Articles of Confederation on July 24,1778, in 1829, gold was discovered in the North Georgia mountains, which led to the Georgia Gold Rush and an established federal mint in Dahlonega, which continued its operation until 1861. The subsequent influx of white settlers put pressure on the government to land from the Cherokee Nation. In 1830, President Andrew Jackson signed the Indian Removal Act into law, sending many eastern Native American nations to reservations in present-day Oklahoma, including all of Georgias tribes. Despite the Supreme Courts ruling in Worcester v. Georgia that ruled U. S. states were not permitted to redraw the Indian boundaries, President Jackson and the state of Georgia ignored the ruling. In 1838, his successor, Martin Van Buren, dispatched troops to gather the Cherokee

Wisconsin is a U. S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, Wisconsin is the 23rd largest state by total area and the 20th most populous. The state capital is Madison, and its largest city is Milwaukee, the state is divided into 72 counties. Wisconsin is second to Michigan in the length of its Great Lakes coastline, Wisconsin is known as Americas Dairyland because it is one of the nations leading dairy producers, particularly famous for its cheese. Manufacturing, especially paper products, information technology, and tourism are major contributors to the states economy. The word Wisconsin originates from the given to the Wisconsin River by one of the Algonquian-speaking Native American groups living in the region at the time of European contact. French explorer Jacques Marquette was the first European to reach the Wisconsin River, arriving in 1673, subsequent French writers changed the spelling from Meskousing to Ouisconsin, and over time this became the name for both the Wisconsin River and the surrounding lands. English speakers anglicized the spelling from Ouisconsin to Wisconsin when they began to arrive in numbers during the early 19th century. The legislature of Wisconsin Territory made the current spelling official in 1845, the Algonquin word for Wisconsin and its original meaning have both grown obscure. Interpretations vary, but most implicate the river and the red sandstone that lines its banks, other theories include claims that the name originated from one of a variety of Ojibwa words meaning red stone place, where the waters gather, or great rock. Wisconsin has been home to a variety of cultures over the past 12,000 years. The first people arrived around 10,000 BCE during the Wisconsin Glaciation and these early inhabitants, called Paleo-Indians, hunted now-extinct ice age animals such as the Boaz mastodon, a prehistoric mastodon skeleton unearthed along with spear points in southwest Wisconsin. After the ice age ended around 8000 BCE, people in the subsequent Archaic period lived by hunting, fishing, agricultural societies emerged gradually over the Woodland period between 1000 BCE to 1000 CE. Toward the end of period, Wisconsin was the heartland of the Effigy Mound culture. Later, between 1000 and 1500 CE, the Mississippian and Oneota cultures built substantial settlements including the village at Aztalan in southeast Wisconsin. The Oneota may be the ancestors of the modern Ioway and Ho-Chunk tribes who shared the Wisconsin region with the Menominee at the time of European contact, the first European to visit what became Wisconsin was probably the French explorer Jean Nicolet. He canoed west from Georgian Bay through the Great Lakes in 1634, pierre Radisson and Médard des Groseilliers visited Green Bay again in 1654–1666 and Chequamegon Bay in 1659–1660, where they traded for fur with local Native Americans. In 1673, Jacques Marquette and Louis Jolliet became the first to record a journey on the Fox-Wisconsin Waterway all the way to the Mississippi River near Prairie du Chien

Michigan /ˈmɪʃᵻɡən/ is a state in the Great Lakes and Midwestern regions of the United States. The name Michigan is the French form of the Ojibwa word mishigamaa, Michigan is the tenth most populous of the 50 United States, with the 11th most extensive total area. Its capital is Lansing, and its largest city is Detroit, Michigan is the only state to consist of two peninsulas. The Lower Peninsula, to which the name Michigan was originally applied, is noted to be shaped like a mitten. The Upper Peninsula is separated from the Lower Peninsula by the Straits of Mackinac, the two peninsulas are connected by the Mackinac Bridge. The state has the longest freshwater coastline of any political subdivision in the world, being bounded by four of the five Great Lakes, as a result, it is one of the leading U. S. states for recreational boating. Michigan also has 64,980 inland lakes and ponds, a person in the state is never more than six miles from a natural water source or more than 85 miles from a Great Lakes shoreline. What is now the state of Michigan was first settled by Native American tribes before being colonized by French explorers in the 17th century, the area was organized as part of the larger Northwest Territory until 1800, when western Michigan became part of the Indiana Territory. Eventually, in 1805, the Michigan Territory was formed, which lasted until it was admitted into the Union on January 26,1837, the state of Michigan soon became an important center of industry and trade in the Great Lakes region and a popular immigrant destination. Though Michigan has come to develop an economy, it is widely known as the center of the U. S. automotive industry. When the first European explorers arrived, the most populous tribes were Algonquian peoples, which include the Anishinaabe groups of Ojibwe, Odaawaa/Odawa, the three nations co-existed peacefully as part of a loose confederation called the Council of Three Fires. The Ojibwe, whose numbers are estimated to have been between 25,000 and 35,000, were the largest, French voyageurs and coureurs des bois explored and settled in Michigan in the 17th century. The first Europeans to reach what became Michigan were those of Étienne Brûlés expedition in 1622, the first permanent European settlement was founded in 1668 on the site where Père Jacques Marquette established Sault Ste. Marie, Michigan as a base for Catholic missions, missionaries in 1671–75 founded outlying stations at Saint Ignace and Marquette. Jesuit missionaries were received by the areas Indian populations, with relatively few difficulties or hostilities. In 1679, Robert Cavelier, Sieur de la Salle built Fort Miami at present-day St. Joseph, in 1691, the French established a trading post and Fort St. Joseph along the St. Joseph River at the present day city of Niles. The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent, cadillacs wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of the first European women to settle in the Michigan wilderness. The town quickly became a major fur-trading and shipping post, the Église de Saint-Anne was founded the same year

Ohio /oʊˈhaɪ. oʊ/ is a Midwestern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, the states capital and largest city is Columbus. The state takes its name from the Ohio River, the name originated from the Iroquois word ohi-yo’, meaning great river or large creek. Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state on March 1,1803, Ohio is historically known as the Buckeye State after its Ohio buckeye trees, and Ohioans are also known as Buckeyes. Ohio occupies 16 seats in the United States House of Representatives, Ohio is known for its status as both a swing state and a bellwether in national elections. Six Presidents of the United States have been elected who had Ohio as their home state, Ohios geographic location has proven to be an asset for economic growth and expansion. Because Ohio links the Northeast to the Midwest, much cargo, Ohio has the nations 10th largest highway network, and is within a one-day drive of 50% of North Americas population and 70% of North Americas manufacturing capacity. To the north, Lake Erie gives Ohio 312 miles of coastline, Ohios southern border is defined by the Ohio River, and much of the northern border is defined by Lake Erie. Ohios neighbors are Pennsylvania to the east, Michigan to the northwest, Ontario Canada, to the north, Indiana to the west, Kentucky on the south, Ohio is bounded by the Ohio River, but nearly all of the river itself belongs to Kentucky and West Virginia. Ohio has only that portion of the river between the rivers 1792 low-water mark and the present high-water mark, the border with Michigan has also changed, as a result of the Toledo War, to angle slightly northeast to the north shore of the mouth of the Maumee River. Much of Ohio features glaciated plains, with a flat area in the northwest being known as the Great Black Swamp. Most of Ohio is of low relief, but the unglaciated Allegheny Plateau features rugged hills, in 1965 the United States Congress passed the Appalachian Regional Development Act, at attempt to address the persistent poverty and growing economic despair of the Appalachian Region. This act defines 29 Ohio counties as part of Appalachia, the worst weather disaster in Ohio history occurred along the Great Miami River in 1913. Known as the Great Dayton Flood, the entire Miami River watershed flooded, as a result, the Miami Conservancy District was created as the first major flood plain engineering project in Ohio and the United States. Grand Lake St. Marys in the west central part of the state was constructed as a supply of water for canals in the era of 1820–1850. For many years this body of water, over 20 square miles, was the largest artificial lake in the world and it should be noted that Ohios canal-building projects were not the economic fiasco that similar efforts were in other states. Some cities, such as Dayton, owe their emergence to location on canals. Summers are typically hot and humid throughout the state, while winters generally range from cool to cold, precipitation in Ohio is moderate year-round

New York is a state in the northeastern United States, and is the 27th-most extensive, fourth-most populous, and seventh-most densely populated U. S. state. New York is bordered by New Jersey and Pennsylvania to the south and Connecticut, Massachusetts, and Vermont to the east. With an estimated population of 8.55 million in 2015, New York City is the most populous city in the United States, the New York Metropolitan Area is one of the most populous urban agglomerations in the world. New York City makes up over 40% of the population of New York State, two-thirds of the states population lives in the New York City Metropolitan Area, and nearly 40% lives on Long Island. Both the state and New York City were named for the 17th-century Duke of York, the next four most populous cities in the state are Buffalo, Rochester, Yonkers, and Syracuse, while the state capital is Albany. New York has a diverse geography and these more mountainous regions are bisected by two major river valleys—the north-south Hudson River Valley and the east-west Mohawk River Valley, which forms the core of the Erie Canal. Western New York is considered part of the Great Lakes Region and straddles Lake Ontario, between the two lakes lies Niagara Falls. The central part of the state is dominated by the Finger Lakes, New York had been inhabited by tribes of Algonquian and Iroquoian-speaking Native Americans for several hundred years by the time the earliest Europeans came to New York. The first Europeans to arrive were French colonists and Jesuit missionaries who arrived southward from settlements at Montreal for trade, the British annexed the colony from the Dutch in 1664. The borders of the British colony, the Province of New York, were similar to those of the present-day state, New York is home to the Statue of Liberty, a symbol of the United States and its ideals of freedom, democracy, and opportunity. In the 21st century, New York has emerged as a node of creativity and entrepreneurship, social tolerance. On April 17,1524 Verrazanno entered New York Bay, by way of the now called the Narrows into the northern bay which he named Santa Margherita. Verrazzano described it as a vast coastline with a delta in which every kind of ship could pass and he adds. This vast sheet of water swarmed with native boats and he landed on the tip of Manhattan and possibly on the furthest point of Long Island. Verrazannos stay was interrupted by a storm which pushed him north towards Marthas Vineyard, in 1540 French traders from New France built a chateau on Castle Island, within present-day Albany, due to flooding, it was abandoned the next year. In 1614, the Dutch under the command of Hendrick Corstiaensen, rebuilt the French chateau, Fort Nassau was the first Dutch settlement in North America, and was located along the Hudson River, also within present-day Albany. The small fort served as a trading post and warehouse, located on the Hudson River flood plain, the rudimentary fort was washed away by flooding in 1617, and abandoned for good after Fort Orange was built nearby in 1623. Henry Hudsons 1609 voyage marked the beginning of European involvement with the area, sailing for the Dutch East India Company and looking for a passage to Asia, he entered the Upper New York Bay on September 11 of that year

Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Illinois

Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 6th most populous state and 25th largest state in terms of land area, the word Illinois comes from a French rendering of a native Algonquin word. For decades, OHare International Airport has been ranked as one of the worlds busiest airports, Illinois has long had a reputation as a bellwether both in social and cultural terms and politics. With the War of 1812 Illinois growth slowed as both Native Americans and Canadian forces often raided the American Frontier, mineral finds and timber stands also had spurred immigration—by the 1810s, the Eastern U. S. Railroads arose and matured in the 1840s, and soon carried immigrants to new homes in Illinois, as well as being a resource to ship their commodity crops out to markets. Railroads freed most of the land of Illinois and other states from the tyranny of water transport. By 1900, the growth of jobs in the northern cities and coal mining in the central and southern areas attracted a new group of immigrants. Illinois was an important manufacturing center during both world wars, the Great Migration from the South established a large community of African Americans in Chicago, who created the citys famous jazz and blues cultures. Three U. S. presidents have been elected while living in Illinois, Abraham Lincoln, Ulysses S. Grant, additionally, Ronald Reagan, whose political career was based in California, was the only U. S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official slogan, Land of Lincoln. The Abraham Lincoln Presidential Library and Museum is located in the capital of Springfield. Illinois is the spelling for the early French Catholic missionaries and explorers name for the Illinois Native Americans. American scholars previously thought the name Illinois meant man or men in the Miami-Illinois language and this etymology is not supported by the Illinois language, as the word for man is ireniwa and plural men is ireniwaki. The name Illiniwek has also said to mean tribe of superior men. The name Illinois derives from the Miami-Illinois verb irenwe·wa he speaks the regular way and this was taken into the Ojibwe language, perhaps in the Ottawa dialect, and modified into ilinwe·. The French borrowed these forms, changing the ending to spell it as -ois. The current spelling form, Illinois, began to appear in the early 1670s, the Illinois name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans, the Koster Site has been excavated and demonstrates 7,000 years of continuous habitation

Long Island

Long Island is an island located just off the northeast coast of the United States and a region within the U. S. state of New York. Stretching east-northeast from New York Harbor into the Atlantic Ocean, the island comprises four counties, Kings and Queens to the west, then Nassau, more generally, Long Island may also refer collectively both to the main Island as well as its nearby, surrounding outer barrier islands. North of the island is the Long Island Sound, across from which lie the states of Connecticut, across the Sound, to the northwest, lies Westchester County on mainland New York. To the west, Long Island is separated from the Bronx and the island of Manhattan by the East River. To the extreme southwest, it is separated from the New York City borough of Staten Island and the U. S. state of New Jersey by Upper New York Bay, the Narrows, to the east lie Block Island and numerous smaller islands. Its population density is 5,595.1 inhabitants per square mile, Long Island is culturally and ethnically diverse. Some of the wealthiest and most expensive neighborhoods in the Western Hemisphere are located on Long Island, nine bridges and 13 tunnels connect Brooklyn and Queens to the three other boroughs of New York City. Ferries connect Suffolk County northward across Long Island Sound to the state of Connecticut, the Long Island Rail Road is the busiest commuter railroad in North America and operates 24/7. At the time of European contact, the Lenape people inhabited the western end of Long Island, giovanni da Verrazzano was the first European to record an encounter with the Lenapes, after entering what is now New York Bay in 1524. In 1609, the English navigator Henry Hudson explored the harbor, adriaen Block followed in 1615 and is credited as the first European to determine that both Manhattan and Long Island are islands. Native American land deeds recorded by the Dutch from 1636 state that the Indians referred to Long Island as Sewanhaka, sewan was one of the terms for wampum, and is also translated as loose or scattered, which may refer either to the wampum or to Long Island. The name t Lange Eylandt alias Matouwacs appears in Dutch maps from the 1650s, later, the English referred to the land as Nassau Island, after the Dutch Prince William of Nassau, Prince of Orange. It is unclear when the name Nassau Island was discontinued, the very first settlements on Long Island were by settlers from England and its colonies in present-day New England. Lion Gardiner settled nearby Gardiners Island, the first settlement on the geographic Long Island itself was on October 21,1640, when Southold was established by the Rev. John Youngs and settlers from New Haven, Connecticut. Peter Hallock, one of the settlers, drew the long straw and was granted the honor to step ashore first and he is considered the first New World settler on Long Island. Southampton was settled in the same year, Hempstead followed in 1644, East Hampton in 1648, Huntington in 1653, and Brookhaven in 1655. While the eastern region of Long Island was first settled by the English, until 1664, the jurisdiction of Long Island was split, roughly at the present border between Nassau County and Suffolk County. The Dutch founded six towns in present-day Brooklyn beginning in 1645 and these included, Brooklyn, Gravesend, Flatlands, Flatbush, New Utrecht, and Bushwick

Helianthus anomalus

Helianthus anomalus is a species of plants in the sunflower family, found in the southwestern United States. Helianthus anomalus is of particular interest due to its genetics and it was produced via hybridization of two other sunflower species, H. annuus and H. petiolaris, multiple times between approximately 60,000 and 200,000 years ago. From these two parent plants, three hybrids were formed, each with distinct characteristics and habitat preferences, Helianthus anomalus is found in the United States in Arizona, New Mexico, Nevada and Utah. Both H. anomalus hybrids are subject to ecological conditions. They grow in sand dune habitats, which have limited access to nitrogen and water, Helianthus anomalus is native to these states, not introduced. Helianthus anomalus has unique traits that allows it to thrive in its sand dune environment. Helianthus anomalus has a high leaf succulence, which allows it to long periods of drought common to its habitat. The succulent leaves of the sunflower stores water in absorbent, spongy portions of the leaves, Helianthus anomalus also has large seeds and rapid root growth, which contribute to its ability to survive in its extreme environment. It is believed that large seeds are adaptive to dune plants because the seed size prevents burial by the sand. Helianthus anomalus is an annual plant, individuals of this species can be recognized by their yellow flowers, with alternate oval shaped leaves. H. anomalus produces achenes for fruits, a 2001 study done on multiple species of Helianthus showed the average height of the plant to be 1. 2m, with an average leaf length of 9.69 cm. Their average root length of 6.45 cm is an adaptation to their dry environment, the large size of their achenes facilitates this expanding root growth. Helianthus anomalus is of particular interest to biologists because it is a natural hybrid, the parental flowers, H. annuus and H. petiolaris, are found in dramatically different environments. H annuus is found in clay based soils while H. petiolaris is found in sandier soils, the hybrid flower, H. anomalus, is able to inhabit such a different and stressful environment due to divergence in parental gene dominance. Common garden experiments of the parental and hybrid flowers show distinct preference to their different habitats, Helianthus anomalus has been considered a potential source of alternate fuel. The need for fuel sources has been a pressing issue over the past ten years. Among the 51 species of the Helianthus genus, H. anomalus shows promise because of its high oil concentration, linoleic fatty acid concentration and its large achenes

Nevada is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, nearly three-quarters of Nevadas people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the states four largest incorporated cities are located. Nevada is officially known as the Silver State because of the importance of silver to its history and economy. It is also known as the Battle Born State, because it achieved statehood during the Civil War, as the Sage-brush State, for the plant of the same name. Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, Nevada is largely desert and semi-arid, much of it located within the Great Basin. Areas south of the Great Basin are located within the Mojave Desert, while Lake Tahoe, about 86% of the states land is managed by various jurisdictions of the U. S. federal government, both civilian and military. Before European contact, Native Americans of the Paiute, Shoshone, the first Europeans to explore the region were Spanish. They called the region Nevada because of the snow covered the mountains in winter. The area formed part of the Viceroyalty of New Spain, the United States annexed the area in 1848 after its victory in the Mexican–American War, and it was incorporated as part of Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31,1864, as the second of two added to the Union during the Civil War. Nevada has a reputation for its libertarian laws, in 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populated state. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century, Nevada is the only U. S. state where prostitution is legal, though it is illegal in Clark County, Washoe County and Carson City. The tourism industry remains Nevadas largest employer, with mining continuing as a sector of the economy. The name Nevada comes from the Spanish nevada, meaning snow-covered, most Nevadans pronounce the second syllable of their state name using the vowel of trap. Many from outside the Western United States pronounce it with the vowel of father, although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation preferred by most Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate pronunciation of Nevada, though the bill was not supported by most legislators, the Nevadan pronunciation is the de facto official one, since it is the one used by the state legislature. Nevada is almost entirely within the Basin and Range Province, and is broken up by many mountain ranges

The Utah Railway is a class III railroad operating in Utah and Colorado, and owned by Genesee & Wyoming Inc. The Utah Railway Company was incorporated on January 24,1912, with the name of Utah Coal Railway, shortened to Utah Railway in May of the same year. It was founded to haul coal from the mines to Provo, Utah, in reaction to company disappointment in the service and route of the existing Denver. In addition, the Utah Railway was the first to equip its air brakes with fourteen-pound tension springs instead of the standard seven-pound springs and these gondolas were known to the railroads employees as Battleships. Parent company Mueller Industries, a manufacturer of products, sold the Utah Railway in 2002 to Genesee & Wyoming Inc. a railroad holding company. As of January,2017, the no longer hauls coal. The Utah Railway also owns a railroad, the Salt Lake City Southern Railroad. In addition, switching services are provided in Ogden and elsewhere, the earliest logo was simply the words Utah Railway Company, spelled out on the locomotives and cabooses, and Utah Coal Route on the drop-bottom gondolas. On paper, however, the logo for many years was a circle with a white background. The wording and image in these circular logos changed over the years, the 1948 logo included the words Utah Railway surrounding a gondola with the initials U. C. R. The 1999 logo was an oval with an image of an SD diesel locomotive, in later years the symbol of the Utah Railway Company was the beehive, which is also the Utah state symbol.

Arizona is a state in the southwestern region of the United States. It is also part of the Western United States and the Mountain West states and it is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix, Arizona is one of the Four Corners states. It has borders with New Mexico, Utah, Nevada, California, and Mexico, Arizonas border with Mexico is 389 miles long, on the northern border of the Mexican states of Sonora and Baja California. Arizona is the 48th state and last of the states to be admitted to the Union. Historically part of the territory of Alta California in New Spain, after being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase, Southern Arizona is known for its desert climate, with very hot summers and mild winters. There are ski resorts in the areas of Flagstaff, Alpine, in addition to the Grand Canyon National Park, there are several national forests, national parks, and national monuments. To the European settlers, their pronunciation sounded like Arissona, the area is still known as alĭ ṣonak in the Oodham language. Another possible origin is the Basque phrase haritz ona, as there were numerous Basque sheepherders in the area, There is a misconception that the states name originated from the Spanish term Árida Zona. See also lists of counties, islands, rivers, lakes, state parks, national parks, Arizona is in the Southwestern United States as one of the Four Corners states. Arizona is the sixth largest state by area, ranked after New Mexico, of the states 113,998 square miles, approximately 15% is privately owned. The remaining area is public forest and park land, state trust land, Arizona is well known for its desert Basin and Range region in the states southern portions, which is rich in a landscape of xerophyte plants such as the cactus. This regions topography was shaped by volcanism, followed by the cooling-off. Its climate has hot summers and mild winters. The state is well known for its pine-covered north-central portion of the high country of the Colorado Plateau. Like other states of the Southwest United States, Arizona has an abundance of mountains, despite the states aridity, 27% of Arizona is forest, a percentage comparable to modern-day France or Germany. The worlds largest stand of pine trees is in Arizona

New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the Union as the 47th state on January 6,1912 and it is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, inhabited by Native Americans for thousands of years before European exploration, New Mexico was colonized by the Spanish in 1598 Imperial Spanish viceroyalty of New Spain. Later, it was part of independent Mexico before becoming a U. S. territory and eventually a U. S. state as a result of the Mexican–American War. Among U. S. states, New Mexico has the highest percentage of Hispanics, the major Native American nations in the state are Navajo, Pueblo, and Apache peoples. The demography and culture of the state are shaped by these strong Hispanic and Native American influences and its scarlet and gold colors are taken from the royal standards of Spain, along with the ancient sun symbol of the Zia, a Pueblo-related tribe. New Mexico, or Nuevo México in Spanish, is incorrectly believed to have taken its name from the nation of Mexico. The name simply stuck, even though the area had no connection to Mexico or the Mexica Indian tribes, Mexico, formerly a part of New Spain, adopted its name centuries later in 1821, after winning independence from Spanish rule. New Mexico was a part of the independent Mexican Empire and Federal Republic of Mexico for 27 years,1821 through 1848, New Mexico and Mexico developed as neighboring Spanish-speaking communities under Spanish rule, with relatively independent histories. The states total area is 121,412 square miles, the eastern border of New Mexico lies along 103° W longitude with the state of Oklahoma, and 2.2 miles west of 103° W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, the western border with Arizona runs along the 109°03 W longitude. The southwestern corner of the state is known as the Bootheel, the 37° N latitude parallel forms the northern boundary with Colorado. The states New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in the corner of New Mexico. New Mexico, although a state, has very little water. Its surface water area is about 250 square miles, the New Mexican landscape ranges from wide, rose-colored deserts to broken mesas to high, snow-capped peaks. Despite New Mexicos arid image, heavily forested mountain wildernesses cover a significant portion of the state, the Sangre de Cristo Mountains, the southernmost part of the Rocky Mountains, run roughly north-south along the east side of the Rio Grande in the rugged, pastoral north. The most important of New Mexicos rivers are the Rio Grande, Pecos, Canadian, San Juan, the Rio Grande is tied for the fourth-longest river in the United States. Tourists visiting these sites bring significant money to the state, other areas of geographical and scenic interest include Kasha-Katuwe Tent Rocks National Monument and the Gila Wilderness in the southwest of the state
