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

Plant
–
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
5.
Rosids
–
The rosids are members of a large clade of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification and these orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period, molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. The name is based upon the name Rosidae, which had usually been understood to be a subclass, in 1967, Armen Takhtajan showed that the correct basis for the name Rosidae is a description of a group of plants published in 1830 by Friedrich Gottlieb Bartling. The clade was later renamed Rosidae and has been variously delimited by different authors, the name rosids is informal and not assumed to have any particular taxonomic rank like the names authorized by the ICBN. The rosids are monophyletic based upon evidence found by molecular phylogenetic analysis, three different definitions of the rosids were used. Some authors included the orders Saxifragales and Vitales in the rosids, others excluded both of these orders. The circumscription used in this article is that of the APG IV classification, which includes Vitales, the rosids and Saxifragales form the superrosids clade. This is one of three groups compose the Pentapetalae, the others being Dilleniales and the superasterids. The rosids consist of two groups, the order Vitales and the eurosids, the eurosids, in turn, are divided into two groups, fabids and malvids. The rosids consist of 17 orders, in addition to Vitales, there are 8 orders in fabids and 8 orders in malvids. Some of the orders have only recently been recognized and these are Vitales, Zygophyllales, Crossosomatales, Picramniales, and Huerteales. The phylogeny of Rosids shown below is adapted from the Angiosperm Phylogeny Group website, the nitrogen-fixing clade contains a high number of actinorhizal plants. Not all plants in this clade are actinorhizal, however, media related to Rosids at Wikimedia Commons

Myrtales
–
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the Eucalyptus grandis genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids, the following families are included as of APG III, Alzateaceae S. A. Graham Combretaceae R. Br. The Cronquist system gives essentially the composition, except the Vochysiaceae are removed to the order Polygalales. The families Sonneratiaceae, Trapaceae, and Punicaceae are removed from the Lythraceae, in the classification system of Dahlgren the Myrtales were in the superorder Myrtiflorae. The APG III system agrees with the older Cronquist circumscriptions of treating Psiloxylaceae and Heteropyxidaceae within Myrtaceae, ellagitannins are reported in dicotyledoneous angiospermes, and notably in species in the order Myrtales. Myrtales is dated to have begun 89-99 million years ago in Australasia, there is some contention as to that date however, which was obtained using nuclear DNA. When looking at chloroplast DNA, the ancestor is instead considered to have evolved in the mid-cretaceous period in Southeast Africa. Although the APG system classifies myrtales as within the eurosids, the published genome of Eucalyptus grandis places the order myrtales as a sister to the eurosids rather than inside them. The discrepancy is thought to have due to the difference between using a large number of taxa versus using a large number of genes for constructing a phylogeny. Conti, E. Erikkson, T. Schonenberger, J. Sytsma, K. J. Baum, early Tertiary Out-of-India Dispersal of Crypteroniaceae, Evidence from Phylogeny and Molecular Dating. Schönenberger, J. Conti, E.

Myrtaceae
–
Myrtaceae is the myrtle family, a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pohutukawa, the bay rum tree, clove, guava, acca, allspice, all species are woody, with essential oils, and flower parts in multiples of four or five. One notable character of the family is that the phloem is located on both sides of the xylem, not just outside as in most other plants, the leaves are evergreen, alternate to mostly opposite, simple, and usually with an entire margin. The flowers have a number of five petals, though in several genera the petals are minute or absent. The stamens are usually conspicuous, brightly coloured and numerous. Recent estimates suggest the Myrtaceae include approximately 5950 species in ca 132 genera, the family has a wide distribution in tropical and warm-temperate regions of the world, and are typically common in many of the worlds biodiversity hotspots. Genera with capsular fruits such as Eucalyptus, Corymbia, Angophora, Leptospermum, genera with fleshy fruits have their greatest concentrations in eastern Australia and Malesia and the Neotropics. Eucalyptus is a dominant, nearly ubiquitous genus in the more parts of Australia. Eucalyptus regnans is the tallest flowering plant in the world, other important Australian genera are Callistemon, Syzygium, and Melaleuca. Species of the genus Osbornia, native to Australasia, are mangroves, eugenia, Myrcia, and Calyptranthes are among the larger genera in the neotropics. Historically, the Myrtaceae were divided into two subfamilies, subfamily Myrtoideae was recognized as having fleshy fruits and opposite, entire leaves. Most genera in this subfamily have one of three recognized types of embryos. The genera of Myrtoideae can be difficult to distinguish in the absence of mature fruits. Myrtoideae are found worldwide in subtropical and tropical regions, with centers of diversity in the Neotropics, northeastern Australia, in contrast, subfamily Leptospermoideae was recognized as having dry, dehiscent fruits and leaves arranged spirally or alternate. The Leptospermoideae are found mostly in Australasia, with a centre of diversity in Australia, many genera in Western Australia have greatly reduced leaves and flowers typical of more xeric habitats. Thus, many workers are now using a recent analysis by Wilson et al. as a point to test further analyses of the family. The genera Heteropyxis and Psiloxylon have been separated as separate families by many authors in the past as Heteropyxidaceae and Psiloxylaceae, however, Wilson et al. included them in Myrtaceae. These two genera are believed to be the earliest arising and surviving lineages of Myrtaceae

Eucalyptus
–
Eucalyptus /ˌjuːkəˈlɪptəs/ LHeritier 1789 is a diverse genus of flowering trees and shrubs in the myrtle family, Myrtaceae. Members of the genus dominate the flora of Australia. There are more than 700 species of eucalyptus and most are native to Australia, one species, Eucalyptus deglupta, ranges as far north as the Philippines. Of the 15 species found outside Australia, just nine are exclusively non-Australian, species of eucalyptus are cultivated widely in the tropical and temperate world, including the Americas, Europe, Africa, the Mediterranean Basin, the Middle East, China, and the Indian subcontinent. However, the range over which many eucalypts can be planted in the zone is constrained by their limited cold tolerance. Australia is covered by 92,000,000 hectares of eucalypt forest, Eucalyptus is one of three similar genera that are commonly referred to as eucalypts, the others being Corymbia and Angophora. Many species, though by no means all, are known as gum trees because they exude copious kino from any break in the bark. The generic name is derived from the Greek words ευ well and καλύπτω to cover, Eucalyptus oil finds many uses like in aromatherapy, as a cure for joint pains. Eucalyptus trees show allelopathic effects, they release compounds which inhibit other plant species from growing nearby, on warm days, eucalyptus forests are sometimes shrouded in a smog-like mist of vaporised volatile organic compounds, the Australian Blue Mountains take their name from the haze. A mature eucalyptus may take the form of a low shrub or a large tree. The species can be divided into three main habits and four size categories, as a generalisation forest trees are single-stemmed and have a crown forming a minor proportion of the whole tree height. Woodland trees are single-stemmed, although they may branch at a distance above ground level. Many mallee trees may be so low-growing as to be considered a shrub, two other tree forms are notable in Western Australia and described using the native names mallet and marlock. The mallet is a small to medium-sized tree that does not produce lignotubers and has a long trunk. This is the habit of mature healthy specimens of Eucalyptus occidentalis, E. astringens, E. spathulata, E. gardneri, E. dielsii, E. forrestiana, E. salubris, E. clivicola. The smooth bark of mallets often has a satiny sheen and may be white, cream, grey, green, or copper. The term marlock has been used, in Forest Trees of Australia, it is defined as a small tree without lignotubers. They usually grow in more or less pure stands, clearly recognisable examples are stands of E. platypus, E. vesiculosa, and the unrelated E. stoatei

Binomial nomenclature
–
Such a name is called a binomial name, a binomen, binominal name or a scientific name, more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs, for example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of system of naming species is credited to Carl Linnaeus. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus. Although the general principles underlying binomial nomenclature are common to these two codes, there are differences, both in the terminology they use and in their precise rules. Similarly, both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a name is usually given, at least when it is first mentioned. In zoology Patella vulgata Linnaeus,1758, the original name given by Linnaeus was Fringilla domestica, the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, in botany Amaranthus retroflexus L. – L. is the standard abbreviation used in botany for Linnaeus. – Linnaeus first named this bluebell species Scilla italica, Rothmaler transferred it to the genus Hyacinthoides, the ICN does not require that the dates of either publication be specified. Prior to the adoption of the binomial system of naming species. Together they formed a system of polynomial nomenclature and these names had two separate functions. First, to designate or label the species, and second, to be a diagnosis or description, such polynomial names may sometimes look like binomials, but are significantly different. For example, Gerards herbal describes various kinds of spiderwort, The first is called Phalangium ramosum, Branched Spiderwort, is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia. The Latin phrases are short descriptions, rather than identifying labels, the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné. It was in his 1753 Species Plantarum that he first began using a one-word trivial name together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as an epithet or specific name

Allan Cunningham (botanist)
–
Allan Cunningham was an English botanist and explorer, primarily known for his travels in Australia to collect plants. Cunningham was born in Wimbledon, Surrey, the son of Allan Cunningham, who came from Renfrewshire, Scotland, Allan Cunningham was educated at a Putney private school, Reverend John Adams Academy and then went into a solicitors office. He afterwards obtained a position with William Townsend Aiton superintendent of Kew Gardens, on Banks recommendation, Cunningham went to Brazil with James Bowie between 1814 and 1816 collecting specimens for Kew Gardens. On 28 September 1816 he sailed for Sydney where he arrived on 20 December 1816, among other explorations, he joined John Oxleys 1817 expedition beyond the Blue Mountains to the Lachlan and Macquarie rivers and shared in the privations of the 1,200 miles journey. He was able to collect specimens of about 450 species and gained experience as an explorer. Cunningham traveled as the ships botanist aboard HMS Mermaid under Phillip Parker King from 1817 to 1820, the Mermaid was of only 85 tons, but sailing on 22 December 1817 they reached King George Sound on 21 January 1818. Though their stay was short many specimens were found but the islands on the west coast were comparatively barren, towards the end of March the Goulburn Islands on the north coast were reached and many new plants were discovered. They reached Timor on 4 June 1818 and, turning for home, Cunninghams collections during this voyage included about 300 species. Shortly after his return, Cunningham made an excursion south from Sydney, ascending the prominent peak of Mount Keira overlooking the Illawarra region, towards the end of the year he made a voyage to Tasmania arriving at Hobart on 2 January 1819. He next visited Launceston and though often finding the botany interesting, he found little that was absolutely new, in May he went with King in the Mermaid on a second voyage to the north and north-west coasts. On this occasion they started up the east coast and Cunningham found many opportunities for adding to his collections, one of these was after the ship reached the mouth of the Endeavour River on 28 June 1819. The circumnavigation of Australia was completed on 27 August when they reached Vernon Island in Clarence Strait and they again visited Timor and arrived back in Sydney on 12 January 1820. The third voyage to the north coast with King began on 15 June, but meeting bad weather the bowsprit was lost, sailing again on 13 July 1820 the northerly course was followed and eventually the continent was circumnavigated. The Mermaid was then condemned and the voyage was on the Bathurst which was twice the size of the Mermaid. They left on 26 May 1821, the route was chosen, and when they were on the west coast of Australia it was found necessary to go to Mauritius to refit. They left after a stay of seven weeks and reached King George Sound on 24 December 1821. A sufficiently long stay was made for Cunningham to make an excellent collection of plants, Sydney was reached again on 25 April 1822. Cunningham provided a chapter on botany to Kings Narrative of a Survey, in September 1822 Cunningham went on an expedition over the Blue Mountains and arrived at Bathurst on 14 October 1822 and returned to Parramatta in January 1823

Leaves
–
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

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

Glossary of leaf morphology
–
The following is a defined list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple or compound, the edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article, leaves of most plants include a flat structure called the blade or lamina, but not all leaves are flat, some are cylindrical. Leaves may be simple, with a leaf blade, or compound. In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules, leaf structure is described by several terms that include, Being one of the more visible features, leaf shape is commonly used for plant identification. Edge and margin are both interchangeable in the sense that they refer to the perimeter of a leaf. Leaves may also be folded or rolled in various ways, the folding of leaves within a bud is vernation, ptyxis is the folding of an individual leaf in a bud
14.
Vein
–
Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the back to the heart, exceptions are the pulmonary and umbilical veins. In contrast to veins, arteries carry blood away from the heart, veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow, veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, superficial veins are those closer to the surface of the body, and have no corresponding arteries. Deep veins are deeper in the body and have corresponding arteries, perforator veins drain from the superficial to the deep veins. These are usually referred to in the limbs and feet. Communicating veins are veins that directly connect superficial veins to deep veins, pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart. Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart, most veins are equipped with valves to prevent blood flowing in the reverse direction. Veins appear blue because the subcutaneous fat absorbs low-frequency light, permitting only the highly energetic blue wavelengths to penetrate through to the dark vein and reflect back to the viewer. The colour of a vein can be affected by the characteristics of a skin, how much oxygen is being carried in the blood. When a vein is drained of blood and removed from an organism, the largest veins in the human body are the venae cavae. These are two large veins which enter the right atrium of the heart from above and below. The superior vena cava carries blood from the arms and head to the atrium of the heart, while the inferior vena cava carries blood from the legs. The inferior vena cava is retroperitoneal and runs to the right, large veins feed into these two veins, and smaller veins into these. Together this forms the venous system, whilst the main veins hold a relatively constant position, the position of veins person to person can display quite a lot of variation. The pulmonary veins carry relatively oxygenated blood from the lungs to the heart, the superior and inferior venae cavae carry relatively deoxygenated blood from the upper and lower systemic circulations, respectively. The portal venous system is a series of veins or venules that directly connect two capillary beds, examples of such systems include the hepatic portal vein and hypophyseal portal system

Victoria (Australia)
–
Victoria is a state in southeast Australia. Victoria is Australias most densely populated state and its second-most populous state overall, most of its population is concentrated in the area surrounding Port Phillip Bay, which includes the metropolitan area of its state capital and largest city, Melbourne, Australias second-largest city. Prior to British European settlement, the area now constituting Victoria was inhabited by a number of Aboriginal peoples. With Great Britain having claimed the entire Australian continent east of the 135th meridian east in 1788, Victoria was included in the wider colony of New South Wales. The first settlement in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in the Port Phillip District in 1836, Victoria was officially created as a separate colony in 1851, and achieved self-government in 1855. Politically, Victoria has 37 seats in the Australian House of Representatives and 12 seats in the Australian Senate, at state level, the Parliament of Victoria consists of the Legislative Assembly and the Legislative Council. Victoria is currently governed by the Labor Party, with Daniel Andrews the current Premier, the personal representative of the Queen of Australia in the state is the Governor of Victoria, currently Linda Dessau. Local government is concentrated in 79 municipal districts, including 33 cities, although a number of unincorporated areas still exist, Victorias total gross state product is ranked second in Australia, although Victoria is ranked fourth in terms of GSP per capita because of its limited mining activity. Culturally, Melbourne is home to a number of museums, art galleries and theatres and is described as the sporting capital of Australia. The Melbourne Cricket Ground is the largest stadium in Australia, and the host of the 1956 Summer Olympics, Victoria has eight public universities, with the oldest, the University of Melbourne, having been founded in 1853. Victoria, like Queensland, was named after Queen Victoria, who had been on the British throne for 14 years when the colony was established in 1851. The first British settlement in the later known as Victoria was established in October 1803 under Lieutenant-Governor David Collins at Sullivan Bay on Port Phillip. In the year 1826 Colonel Stewart, Captain S. Wright, fly and the brigs Dragon and Amity, took a number of convicts and a small force composed of detachments of the 3rd and 93rd regiments. Victorias next settlement was at Portland, on the south west coast of what is now Victoria, edward Henty settled Portland Bay in 1834. Melbourne was founded in 1835 by John Batman, who set up a base in Indented Head, from settlement the region around Melbourne was known as the Port Phillip District, a separately administered part of New South Wales. Shortly after the now known as Geelong was surveyed by Assistant Surveyor W. H. Smythe. And in 1838 Geelong was officially declared a town, despite earlier white settlements dating back to 1826, days later, still in 1851 gold was discovered near Ballarat, and subsequently at Bendigo. Later discoveries occurred at sites across Victoria

New South Wales
–
New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south and it has a coast line with the Tasman Sea on its east side. The Australian Capital Territory is an enclave within the state, New South Wales state capital is Sydney, which is also Australias most populous city. In March 2014, the population of New South Wales was 7.5 million. Just under two-thirds of the population,4.67 million. Inhabitants of New South Wales are referred to as New South Welshmen, the Colony of New South Wales was founded as a penal colony in 1788. It originally comprised a more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825, in addition, the colony also included the island territories of New Zealand, Van Diemens Land, Lord Howe Island, and Norfolk Island. During the 19th century, most of the area was detached to form separate British colonies that eventually became New Zealand. However, the Swan River Colony has never administered as part of New South Wales. Lord Howe Island remains part of New South Wales, while Norfolk Island has become a federal Territory, as have the now known as the Australian Capital Territory. The prior inhabitants of New South Wales were the Aboriginal tribes who arrived in Australia about 40,000 to 60,000 years ago, before European settlement there were an estimated 250,000 Aboriginal people in the region. The Wodi Wodi people are the custodians of the Illawarra region of South Sydney. The Bundjalung people are the custodians of parts of the northern coastal areas. The European discovery of New South Wales was made by Captain James Cook during his 1770 survey along the eastern coast of the Dutch-named continent of New Holland. In his original journal covering the survey, in triplicate to satisfy Admiralty Orders, Cook first named the land New Wales, however, in the copy held by the Admiralty, he revised the wording to New South Wales. After years of chaos and anarchy after the overthrow of Governor William Bligh, macquaries legacy is still evident today. During the 19th century, large areas were separated to form the British colonies of Tasmania, South Australia, Victoria. Responsible government was granted to the New South Wales colony in 1855, following the Treaty of Waitangi, William Hobson declared British sovereignty over New Zealand in 1840

Queensland
–
Queensland is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west, to the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,750,500, concentrated along the coast, the state is the worlds sixth largest sub-national entity, with an area of 1,852,642 km2. The capital and largest city in the state is Brisbane, Australias third largest city, often referred to as the Sunshine State, Queensland is home to 10 of Australias 30 largest cities and is the nations third largest economy. Tourism in the state, fuelled largely by its tropical climate, is a major industry. Queensland was first inhabited by Aboriginal Australians and Torres Strait Islanders, the first European to land in Queensland was Dutch navigator Willem Janszoon in 1606, who explored the west coast of the Cape York Peninsula near present-day Weipa. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain. The colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney, New South Wales at that time included all of what is now Queensland, Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement was allowed from 1842, the state was named in honour of Queen Victoria, who on 6 June 1859 signed Letters Patent separating the colony from New South Wales. The 6th of June is now celebrated statewide as Queensland Day. Queensland achieved statehood with the Federation of Australia on 1 January 1901, the history of Queensland spans thousands of years, encompassing both a lengthy indigenous presence, as well as the eventful times of post-European settlement. The north-eastern Australian region was explored by Dutch, Spanish and French navigators before being encountered by Lieutenant James Cook in 1770, the Australian Labor Party has its origin as a formal organisation in Queensland and the town of Barcaldine is the symbolic birthplace of the party. June 2009 marked the 150th anniversary of its creation as a colony from New South Wales. The Aboriginal occupation of Queensland is thought to predate 50,000 BC, likely via boat or land bridge across Torres Strait, during the last ice age Queenslands landscape became more arid and largely desolate, making food and other supplies scarce. This led to the worlds first seed-grinding technology, warming again made the land hospitable, which brought high rainfall along the eastern coast, stimulating the growth of the states tropical rainforests. In February 1606, Dutch navigator Willem Janszoon landed near the site of what is now Weipa and this was the first recorded landing of a European in Australia, and it also marked the first reported contact between European and Aboriginal Australian people. The region was explored by French and Spanish explorers prior to the arrival of Lieutenant James Cook in 1770. Cook claimed the east coast under instruction from King George III of the United Kingdom on 22 August 1770 at Possession Island, naming Eastern Australia, including Queensland, the Aboriginal population declined significantly after a smallpox epidemic during the late 18th century

Eucalyptus conica
–
Eucalyptus conica, known as the Fuzzy Box is a common eucalyptus tree of the slopes and plains of New South Wales and adjacent areas in Queensland. Occurring as far north as the Carnarvon Range, growing to 20 metres tall, the bark is grey flaky box type bark with some paler patches, shedding in short ribbons. Adult leaves are lanceolate or narrow-lanceolate in shape,7 to 12 cm long,0.8 to 2.5 cm wide, greyish dull green on both sides. Locally frequent, in grassy or dry sclerophyll woodland, mostly found on decomposed granite, heavily alluvial soils, light loamy soils of medium fertility, north from Wagga Wagga. The gumnuts are conical in shape, a Field Guide to Eucalypts - Brooker & Kleinig volume 1, ISBN 0-909605-62-9 page 259

Eucalyptus albens
–
Eucalyptus albens known as the white box is a common eucalyptus tree of the western slopes and plains of New South Wales and adjacent areas in Queensland and Victoria. An isolated population grows in the southern Flinders Ranges in South Australia, george Bentham described the white box in 1867 from material collected by botanist and explorer, Allan Cunningham, along the Macquarie River. Joseph Henry Maiden had regarded it as a subspecies of Eucalyptus hemiphloia in 1904 and it is related to grey box and inland grey box. Hybridization with grey box has been reported in the Hunter Valley, the scientific and common names is derived from the white deposits over the leaves and gumnuts, while the epithet box comes from the box-like tesselated pattern in the bark. Reaching 15–25 metres high, the box has a branched spreading crown with a straight trunk for around half its total height. Its trunk may reach 0.5 metres diameter at breast height and it has fibrous pale grey bark. The juvenile leaves are round and pale, the white flowers appear in the autumn from March to May. The white box is a tree of grassy woodlands on plains or gently sloping areas. An example is the Leard Forest in Northern NSW, which is regarded as the largest White-Box Grassy Woodland that fits the critically endangered criteria, the heavy and hard wood is used for railway sleepers and fence posts. The flowers produce nectar for the honey industry

Eucalyptus sideroxylon
–
Eucalyptus sideroxylon, or mugga, red ironbark or mugga ironbark, is a small to medium-sized or occasionally tall tree. The bark is persistent on the trunk and large branches, hard and deeply furrowed, dark grey to black, with upper limbs smooth, adult leaves are stalked, lanceolate to 14 x 1.8 cm, sub-glaucous or dull green. Flowers are white, pink, red or pale yellow from early autumn until mid-spring, distribution is wide but sporadic, south-eastern Queensland, widespread on the western slopes and plains of New South Wales south into north-central Victoria. E. sideroxylon is very conspicuous with its unusually black bark often holding copious quantities of kino and it is a very popular ornamental and street tree, Ferntree gully road in Melbourne has an avenue of muggas planted. In the wild muggas grow on soils, often little more than sandy gravel. A former subspecies, Eucalyptus sideroxylon subsp, tricarpa L. A. S. Johnson is currently regarded as a species in its own right - Eucalyptus tricarpa L. A. S. Johnson & K. D. Hill. The wood is hard and dense, and is often used for firewood. It has very high resistance to rotting and can be used for fence posts, heartwood dark red, sapwood pale yellow. Very dense, hard, fine grained timber, difficult to work, has been used for furniture, turnery, boat-building, benchtops. Popular as a furniture timber during the 1990s and early 2000s. At about 1130 kg/m3 it is one of the few timbers that will not float, the leaves are used in the production of cineole based eucalyptus oil. Like all eucalypts, muggas can not be grown from cutting and they are easy to grow from seed, however, and are usually quite true to the parent in form. They are very hardy, needing less than 400mm of rain per year to survive, molecules produced by plants in case of pathogens attacks are called phytoalexins. Such compounds can be implied in the response of plants. High levels of polyphenols in E. sideroxylon wood can explain its natural preservation against rot, Ironbark List of Eucalyptus species Department of Primary Industries, Red Ironbark

Eucalyptus crebra
–
Eucalyptus crebra, commonly known as the narrow-leaved ironbark or narrowleaf red ironbark, is a type of Ironbark tree native to eastern Australia. A member of the large genus Eucalyptus, this tree is in the Myrtaceae family and it is an important source of nectar in the honey industry and its hard, strong timber is used in construction. The Narrow-leaved ironbark was originally described by Victoria state botanist Ferdinand von Mueller in 1859, the specific epithet is the Latin adjective crebra crowded or close together. Within the genus Eucalyptus, it belongs in the subgenus Symphyomyrtus and this plant is a large spreading tree, which may reach 35 m in height. The rough furrowed bark is mottled with yellow and orange. The trees name ironbark stems from the rough and unyielding texture of the cambium on the outmost layer of the plant, in the early days of colonization wood felling was achieved with axe and saw, ironbark stands usually meant a broken ax head. The narrow lanceolate leaves are a uniform greyish-green in colour and measure 7–15 cm in length by 0. 9–1.7 cm wide, the small white flowers appear from late autumn to spring, and are followed by small pods. The Narrow-leaved ironbark is found in eastern Australia, from Picton southwest of Sydney north through New South Wales, the narrow-leaved ironbark is one of the key canopy species of the threatened Cumberland Plain Woodlands. Koalas can consume the leaves, and the flowers are pollinated mainly by insects, the southern or shady side of the trunk is habitat for lichens. The tree has a hard, strong, and dark red timber, a plank has been recorded as being used for Elizabeth Farm, Australias oldest surviving European dwelling. It is used as a tree or to line roadways. It is useful in production as the flowers are heavy in nectar and pollen

Angophora
–
Angophora is a genus of flowering plants in the myrtle family, Myrtaceae, described as a genus in 1797. It is endemic to Australia, where species are distributed in Queensland, New South Wales, the centre of diversity is along the northern and central coast of New South Wales. Angophora is closely related to Corymbia and Eucalyptus, and all three genera are often referred to as eucalypts, collectively the eucalypts, or gum trees, dominate many Australian ecosystems. Angophora can be distinguished from other eucalypts by its oppositely arranged leaves and flowers which lack opercula, taxonomists have long recognised the relationships between the eucalypt taxa, but have not agreed upon a classification scheme. Some have proposed merging Angophora and Corymbia into genus Eucalyptus as subgenera, some authors maintain Angophora as a genus, while others continue to debate the issue. Among the eucalypts, Angophora species were nicknamed apples by European settlers, many are still known commonly as apples today. The opposite leaves are hairy and glandular when new, and mostly hairless when mature, the inflorescence is an arrangement of several clusters of 3 to 7 flowers each. The flower has 4 or 5 small, green sepals, overlapping white petals, the fruit is a papery or slightly woody capsule, usually with thick ribs and a coat of hairs. The following are accepted species, Angophora bakeri, a tree up to 10 metres tall. A tree up to 30 meters tall with smooth, scaly bark, - NSW Angophora × clelandii - hybrid A. bakeri × A. hispida - NSW Angophora crassifolia, a tree up to 15 meters tall endemic to New South Wales. - NSW Angophora × dichromophloia - hybrid, A. costata × A. hispida - NSW Angophora euryphylla, - NSW Angophora exul, a threatened species known only from a small area at Gibraltar Rock, New South Wales. A tree up to 8 meters tall with compound, terminal inflorescences, a common tree up to 30 metres tall - NSW, Qld, and Vic Angophora hispida. A tree or mallee up to 7 meters tall, - NSW Angophora inopina, a vulnerable species. A tree up to 8 metres tall, - NSW Angophora leiocarpa, a tree up to 25 meters tall.

Callitris columellaris is a species of coniferous tree in the family Cupressaceae, native to most of Australia. Common names include White Cypress-pine, Murray River Cypress-pine, and Northern Cypress-pine, Callitris columellaris has been naturalised in Hawaii and in southern Florida. It is a evergreen tree, 4–12 m high, with a trunk up to 50 cm diameter. The leaves are scale-like, 2–6 mm long and 0.5 mm broad, the cones are globose, 1–2 cm diameter, with six triangular scales, which open at maturity to release the seeds.

Brachychiton populneus
–
The extended trunk is a water storage device for survival in a warm dry climate. The bell-shaped flowers are variable in colour while the leaves vary considerably in shape, the leaves are either simple and pointed, or may be 3 -9 lobed. Saplings grow from a drought and fire resistant tap-rooted tuber, seeds are eaten by Aboriginal people after roasting. The soft spongy wood was used for making shields, and the bark as a fibre, the leaves are also used as emergency fodder for drought-affected animal stock. It has been introduced as a tree to south-western Australia, South Africa, Louisiana, California, Arizona. In Western Australia it was observed to be invasive in disturbed areas, horticulturists have hybridised the Kurrajong with related Brachychiton species, including the Queensland bottle tree and Illawarra Flame Tree to produce new garden ornamentals. The specific name pertains to a perceived similarity to genus Populus. Sometimes B. populneus is also known by the names lacebark kurrajong, however, B. discolor is also referred to as the Lacebark Kurrajong, and Bottle Tree is a term commonly applied not only to other species of Brachychiton but to members of other genera around the world. The kurrajong has been recorded as a host plant for the mistletoe species Dendrophthoe glabrescens

Acacia
–
Acacia, commonly known as the wattles or acacias, is a large genus of shrubs, lianas and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially it comprised a group of plant species native to Africa and Australia, controversy erupted in the early 2000s when it became evident that the genus as it stood was not monophyletic, and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia was not closely related to the mainly African lineage that contained A. nilotica—the first and this meant that the Australian lineage would need to be renamed. Botanist Les Pedley named this group Racosperma, which was inconsistently adopted and this was officially adopted, but many botanists from Africa and elsewhere disagreed that this was necessary. A number of species have been introduced to parts of the world. The heterogeneous group varies considerably in habit, from mat-like subshrubs to canopy trees in forest, the genus was first described from Africa by C. F. P. von Martius in 1829. Several hundred combinations in Acacia were published by Pedley in 2003, the genus of 981 species, Acacia s. l. in the subfamily Mimosoideae of the pea family Fabaceae is monophyletic. All but 10 of its species are native to Australia, where it constitutes the largest plant genus, following a controversial decision to choose a new type for Acacia in 2005, the Australian component of Acacia s. l. now retains the name Acacia. At the 2011 International Botanical Congress held in Melbourne, the decision to use the name Acacia, other Acacia s. l. taxa continue to be called Acacia by those who choose to consider the entire group as one genus. Australian species of the genus Paraserianthes s. l. are deemed its closest relatives, the origin of wattle may be an Old Teutonic word meaning to weave. From around 700 A. D. watul was used in Old English to refer to the branches and sticks which formed fences, walls. Since about 1810 it refers to the Australian legumes that provide these branches, acacias in Australia probably evolved their fire resistance about 20 million years ago when fossilised charcoal deposits show a large increase, indicating that fire was a factor even then. With no major mountain ranges or rivers to prevent their spread and they began to form dry, open forests with species of the genera Casuarina, Eucalyptus and Callitris. The southernmost species in the genus are Acacia dealbata, Acacia longifolia, Acacia mearnsii and they are present in all terrestrial habitats, including alpine settings, rainforests, woodlands, grasslands, coastal dunes and deserts. In drier woodlands or forest they are an important component of the understory, elsewhere they may be dominant, as in the Brigalow Belt, Myall woodlands and the eremaean Mulga woodlands. Several of its species bear vertically oriented phyllodes, which are green, broadened leaf petioles that function like leaf blades, some phyllodinous species have a colourful aril on the seed. A few species have rather than leaves. Aborigines of Australia have traditionally harvested the seeds of species, to be ground into flour

Wagga Wagga
–
Wagga Wagga is a major regional city in the Riverina region of New South Wales, Australia. The central business district is focused around the commercial and recreational grid bounded by Best and Tarcutta Streets and the Murrumbidgee River, the main shopping street of Wagga is Baylis Street which becomes Fitzmaurice Street at the northern end. The city is in a valley and much of the city has a problem with urban salinity. The original inhabitants of the Wagga Wagga region were the Wiradjuri people, in 1829, Charles Sturt became the first European explorer to visit the future site of the city. The town, positioned on the site of a ford across the Murrumbidgee, was surveyed and gazetted as a village in 1849, in 1870, the town was gazetted as a municipality. During the negotiations leading to the federation of the Australian colonies, during World War I the town was the starting point for the Kangaroo recruitment march. The Great Depression and the resulting hardship saw Wagga Wagga become the centre of a movement for the Riverina region. Wagga Wagga became a town during World War II with the establishment of a military base at Kapooka and Royal Australian Air Force bases at Forest Hill. After the war, Wagga Wagga was proclaimed as a city in 1946, in 1982 the city was amalgamated with the neighbouring Kyeamba and Mitchell Shires to form the City of Wagga Wagga local government area. Wagga Wagga is at the end of the Riverina region where the slopes of the Great Dividing Range flatten. The city straddles the Murrumbidgee River, one of the rivers of the Murray-Darling Basin. This location astride some of the transport routes in the nation has made Wagga Wagga an important heavy truck depot for a number of companies including Toll Holdings. Wagga Wagga is upstream from the Riverina plain in the mid-catchment range of the Murrumbidgee River in an alluvial valley confined by low bedrock hills, much of Wagga Wagga is on heavy clay soils in a large drainage basin with a small catchment discharge point. Groundwater therefore cannot leave easily, leading to Wagga Wagga having a problem with waterlogged soil and soil salination, urban salination in Wagga Wagga is now the subject of a large multi-pronged approach to prevent further salination and reclaim salt-affected areas. The main shopping street of Wagga Wagga is Baylis Street which becomes Fitzmaurice Street at the northern end, the Wollundry Lagoon is the water focus of the city centre and has been a key element in the development and separation of the north and south parts of the city centre. Major industrial areas of Wagga Wagga include the suburb of Bomen. Thomas Mitchell, the surveyor who served under Lord Wellington named many of the streets after Peninsula War veterans, Wagga Wagga has a temperate climate with hot dry summers and cool to cold winters. Under the Köppen climate classification, the city has a subtropical climate

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Wikidata

Wikidata is a collaboratively edited knowledge base operated by the Wikimedia Foundation. It is intended to provide a source of data which can be used by Wikimedia projects such as Wikipedia. This is similar to the way Wikimedia Commons provides storage for files and access to those files for all Wikimedia projects. Wikidata is powered by the software Wikibase, Wikidata is a document-oriented database, focused on items. Each item represents a topic and is identified by a number, prefixed with the letter Q—for example. This enables the basic information required to identify the topic the item covers to be translated without favouring any language, information is added to items by creating statements. Statements take the form of pairs, with each statement consisting of a property. The creation of the project was funded by donations from the Allen Institute for Artificial Intelligence, the Gordon and Betty Moore Foundation, at this time, only the first phase was available. Historically, a Wikipedia article would include a list of links, being links to articles on the same topic in other editions of Wikipedia. Initially, Wikidata was a repository of interlanguage links. No Wikipedia language editions were able to access Wikidata, so they needed to continue to maintain their own lists of interlanguage links, on 14 January 2013, the Hungarian Wikipedia became the first to enable the provision of interlanguage links via Wikidata. This functionality was extended to the Hebrew and Italian Wikipedias on 30 January, to the English Wikipedia on 13 February, on 23 September 2013, phase 1 went live on Wikimedia Commons. The first aspects of the second phase were deployed on 4 February 2013, the values were initially limited to two data types, with more data types to follow later. The first new type, string, was deployed on 6 March, the ability of the various language editions of Wikipedia to access data added to Wikidata as part of phase two was rolled out progressively between 27 March and 25 April 2013. On 16 September 2015, Wikidata began allowing so-called arbitrary access, for example, in the past the article about Berlin you could not access data about Germany, but with arbitrary access it could. On 27 April 2016 arbitrary access was activated on Wikimedia Commons, phase 3 will involve database querying and the creation of lists based on data stored on Wikidata. As of October 2016 two tools for querying Wikidata were available, AutoList and PetScan, additionally to a public SPARQL endpoint, there is concern that the project is being influenced by lobbying companies, PR professionals and search engine optimizers. As of December 2015, according to Wikimedia statistics, half of the information in Wikidata is unsourced, another 30% is labeled as having come from Wikipedia, but with no indication as to which article

Encyclopedia of Life
–
The Encyclopedia of Life is a free, online collaborative encyclopedia intended to document all of the 1.9 million living species known to science. It is compiled from existing databases and from contributions by experts and non-experts throughout the world and it aims to build one infinitely expandable page for each species, including video, sound, images, graphics, as well as text. In addition, the Encyclopedia incorporates content from the Biodiversity Heritage Library, the project was initially backed by a US$50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation, who provided US$20 million and US$5 million, respectively. The project was led by Jim Edwards and the development team by David Patterson. Today, participating institutions and individual donors continue to support EOL through financial contributions, EOL went live on 26 February 2008 with 30,000 entries. The site immediately proved to be popular, and temporarily had to revert to demonstration pages for two days when it was overrun by traffic from over 11 million views it received. The site relaunched on 5 September 2011 with a redesigned interface, eOLv2 is redesigned to enhance usability and encourage contributions and interactions among users. The product is also internationalized with interfaces provided for English, German, Spanish, French, Galician, Serbian, Macedonian, Arabic, Chinese, Korean and Ukrainian language speakers. On 16 January 2014, EOL launched TraitBank, a searchable, open digital repository for organism traits, measurements, interactions, information about many species is already available from a variety of sources, in particular about the megafauna. Gathering currently available data on all 1.9 million species will take about 10 years, as of September 2011, EOL had information on more than 700,000 species available, along with more than 600,000 photos and millions of pages of scanned literature. The initial focus has been on living species but will later include extinct species, as the discovery of new species is expected to continue, the encyclopedia will grow continuously. The goal of EOL is to serve as a resource for the public, enthusiastic amateurs, educators, students. The Encyclopedia of Life has content partners around the world who share information through the EOL platform, including Wikipedia and its interface is translated at translatewiki. net.

Observations may be added via the website or from a mobile application. The observations provide valuable data to a variety of scientific research projects, museums, botanic gardens, parks. Users of iNaturalist have contributed four million observations since its founding in 2008. INaturalist. org began in 2008 as a UC Berkeley School of Information Masters final project of Nate Agrin, Jessica Kline, Nate Agrin and Ken-ichi Ueda continued work on the site with Sean McGregor, a web developer. In 2011, Ueda began collaboration with Scott Loarie, a fellow at Stanford University. Ueda and Loarie are the current co-directors of iNaturalist. org, on April 24,2014 iNaturalist. org merged with the California Academy of Sciences In 2014, iNaturalist celebrated its one millionth observation. The iNaturalist platform is based on crowdsourcing of data, users of iNaturalist can submit observations of organisms in the form of photographs, sound recordings, or visual sightings. Observations are either casual or research grade, and research grade observations are incorporated into online databases to be utilizable for scientists, iNaturalist is the preferred application for crowd-sourced biodiversity data in Mexico. As of 28 January 2017, the iNaturalist community consisted of almost 400,000 users contributing over 4,300,000 observations of plants, animals, users have created and contributed to over 9000 different projects, spanning hundreds of themes. Project examples include taxa- and location-specific bioblitzes, roadkill observations, animal tracks, the US National Park Service partnered with iNaturalist to record observations from the 2016 National Parks BioBlitz. That project exceeded 100,000 observations in August 2016, list of citizen science projects Official website iNaturalist on Vimeo Introducing iNaturalist by Suzanne Cadwell

International Plant Names Index
–
The International Plant Names Index describes itself as a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes. Coverage of plant names is best at the rank of species, the IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell, but new names, IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium. The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information, the standard of author abbreviations recommended by the International Code of Nomenclature for algae, fungi, and plants is Brummitt and Powell’s Authors of Plant Names. A digital and continually updated list of authors and abbreviations can be consulted online at IPNI, the IPNI provides names that have appeared in scholarly publications, with the objective of providing an index of published names rather than prescribing the accepted botanical nomenclature. The Plant List, a project which was unveiled in 2010. The use of IPNI is free of charge, a similar project, which lists names of fungi, is the Index Fungorum.

Integrated Taxonomic Information System
–
The Integrated Taxonomic Information System is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. The database draws from a community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History, the primary focus of ITIS is North American species, but many groups are worldwide and ITIS continues to collaborate with other international agencies to increase its global coverage. ITIS provides a reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific names, synonyms, and common names for terrestrial, marine, data presented in ITIS are considered public information, and may be freely distributed and copied, though appropriate citation is requested. ITIS is frequently used as the de facto source of data in biodiversity informatics projects. It presents the names in a classification that contains author, date, distributional. In addition, common names are available through ITIS in the official languages of the Americas. ITIS and its partner, Species 2000, cooperate to annually produce the Catalogue of Life. The Catalogue of Lifes goal was to complete the global checklist of 1.9 million species by 2011. As of May 2012, the Catalogue of Life has reached 1.4 million species—a major milestone in its quest to complete the first up-to-date comprehensive catalogue of all living organisms, ITIS and the Catalogue of Life are core to the Encyclopedia of Life initiative announced May 2007. EOL will be largely on various Creative Commons licenses. The newer material has been checked to higher standards of taxonomic credibility, biological taxonomy is not fixed, and opinions about the correct status of taxa at all levels, and their correct placement, are constantly revised as a result of new research. Many aspects of classification remain a matter of scientific judgment, the ITIS database is updated to take account of new research as it becomes available, and the information it yields is likely to represent a fair consensus of modern taxonomic opinion. Records within ITIS include information about how far it has been possible to check and its information should be checked against other sources where these are available, and against the primary research scientific literature where possible

National Center for Biotechnology Information
–
The National Center for Biotechnology Information is part of the United States National Library of Medicine, a branch of the National Institutes of Health. The NCBI is located in Bethesda, Maryland and was founded in 1988 through legislation sponsored by Senator Claude Pepper, the NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a database for the biomedical literature. Other databases include the NCBI Epigenomics database, all these databases are available online through the Entrez search engine. NCBI is directed by David Lipman, one of the authors of the BLAST sequence alignment program. He also leads a research program, including groups led by Stephen Altschul, David Landsman, Eugene Koonin, John Wilbur, Teresa Przytycka. NCBI is listed in the Registry of Research Data Repositories re3data. org, NCBI has had responsibility for making available the GenBank DNA sequence database since 1992. GenBank coordinates with individual laboratories and other databases such as those of the European Molecular Biology Laboratory. Since 1992, NCBI has grown to other databases in addition to GenBank. The NCBI assigns a unique identifier to each species of organism, the NCBI has software tools that are available by WWW browsing or by FTP. For example, BLAST is a sequence similarity searching program, BLAST can do sequence comparisons against the GenBank DNA database in less than 15 seconds. RAG2/IL2RG The NCBI Bookshelf is a collection of freely accessible, downloadable, some of the books are online versions of previously published books, while others, such as Coffee Break, are written and edited by NCBI staff. BLAST is a used for calculating sequence similarity between biological sequences such as nucleotide sequences of DNA and amino acid sequences of proteins. BLAST is a tool for finding sequences similar to the query sequence within the same organism or in different organisms. It searches the query sequence on NCBI databases and servers and post the results back to the browser in chosen format. Input sequences to the BLAST are mostly in FASTA or Genbank format while output could be delivered in variety of such as HTML, XML formatting. HTML is the output format for NCBIs web-page. Entrez is both indexing and retrieval system having data from sources for biomedical research

The Plant List
–
The Plant List is a list of botanical names of species of plants created by the Royal Botanic Gardens, Kew and the Missouri Botanical Garden and launched in 2010. It is intended to be comprehensive, that is, deal with all names of species. There is a project called the International Plant Names Index. The IPNI aims to provide details of publication and does not aim to determine which are accepted species names, newly published names are automatically added from IPNI to the World Checklist of Selected Plant Families, a database which underlies the Plant List. The Plant List has 1,064,035 scientific plant names of species rank,350,699 are accepted species names, belonging to 642 plant families and 17,020 plant genera. The Plant List accepts approximately 350,699 unique species, with 470,624 synonyms for those species, when The Plant List was launched in 2010, it attracted media attention for its comprehensive approach. Fox News highlighted the number of synonyms encountered, suggesting that this reflected a lack of biodiversity on earth. The Plant List also attracted attention for building on the work of English naturalist Charles Darwin, Kew has added an average of 6,000 species every year since the IK was first published with 400,000 names of species. However, the IK is currently run as part of the IPNI rather than the Plant List.

Natural Resources Conservation Service
–
Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a small agency, currently comprising about 11,000 employees. Its mission is to improve, protect, and conserve resources on private lands through a cooperative partnership with state. While its primary focus has been agricultural lands, it has many technical contributions to soil surveying, classification. NRCS is the agency in this project. The agency was founded largely through the efforts of Hugh Hammond Bennett, bennetts motivation was based on his knowledge of the detrimental effects of soil erosion and the impacts on U. S lands that led to the Dust Bowl in the 1930s. On September 13,1933, the Soil Erosion Service was formed in the Department of the Interior, the Soil Conservation Service was in charge of 500 Civilian Conservation Corps camps between 1933 and 1942. The primary purpose of these camps was erosion control, Hugh Bennett continued as chief, a position he held until his retirement in 1952. On October 20,1994, the agency was renamed to the Natural Resources Conservation Service as part of the Federal Crop Insurance Reform, NRCS offers technical and financial assistance to farmers and ranchers. The financial assistance is authorized by the Farm Bill, a law that is renewed every five years, the 2014 Farm Bill consolidated 23 programs into 15. NRCS offers these services to land owners, conservation districts, tribes. NRCS also collects and shares information on the soil, water, air. The Conservation Title of the Farm Bill provides the funding to agricultural producers, all of these programs are voluntary. Conservation Stewardship Program CSP is targeted to ag producers who maintain a level of environmental stewardship. Regional Conservation Partnership Program RCPP consolidated four programs from the prior 2008 Farm Bill and it aims at more regional or watershed scale projects, rather than individual farms and ranches. ACEP includes technical and financial help to maintain or improve land for agriculture or environmental benefits, landowners volunteer to restore and protect forests in 30 or 10 year contracts. This program hands assisting funds to participants, the project began in 2010 and initially focused on the Mississippi Basin area. The main goal of the project is to implement better methods of managing water drainage from agricultural uses, in October 2011, The National Managing Water, Harvesting Results Summit was held to promote the drainage techniques used in hopes of people adopting them nationwide
