Inflorescence
–
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the part of the shoot of seed plants where flowers are formed. Inflorescence can also be defined as the portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle and the major axis holding the flowers or more branches within the inflorescence is called the rachis, the stalk of each single flower is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower, any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium. The fruiting stage of an inflorescence is known as an infructescence, inflorescences may be simple or complex. The rachis may be one of several types, including Single, Composite, Umbel and these terms are general representations as plants in nature can have a combination of types. Inflorescences usually have modified shoots foliage different from the part of the plant. Considering the broadest meaning of the term, any leaf associated with an inflorescence is called a bract. A bract is usually located at the node where the stem of the inflorescence forms, joined to the main stem of the plant. They serve a variety of functions which include attracting pollinators and protecting young flowers, according to the presence or absence of bracts and their characteristics we can distinguish, Ebracteate inflorescences, No bracts in the inflorescence. Bracteate inflorescences, The bracts in the inflorescence are very specialised, sometimes reduced to small scales and this use is not technically correct, as, despite their normal appearance, these leaves are considered, in fact, bracts, so that leafy inflorescence is preferable. Leafy-bracted inflorescences, Intermediate between bracteate and leafy inflorescence, if many bracts are present and they are strictly connected to the stem, like in the family Asteraceae, the bracts might collectively be called an involucre. If the inflorescence has a unit of bracts further up the stem. Plant organs can grow according to two different schemes, namely monopodial or racemose and sympodial or cymose, the terminal bud keeps growing and forming lateral flowers. A terminal flower is never formed, the terminal bud forms a terminal flower and then dies out. Other flowers then grow from lateral buds, indeterminate and determinate inflorescences are sometimes referred to as open and closed inflorescences respectively. In an indeterminate inflorescence there is no true terminal flower and the stem usually has a rudimentary end, in many cases the last true flower formed by the terminal bud straightens up, appearing to be a terminal flower

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

Monocotyledon
–
Monocotyledons, commonly referred to as monocots, are flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon. However, molecular research has shown that while the monocots form a monophyletic group or clade. Monocots have almost always recognized as a group, but with various taxonomic ranks. The APG III system of 2009 recognises a clade called monocots, the monocots include about 60,000 species. The largest family in this group by number of species are the orchids, about half as many species belong to the true grasses, which are economically the most important family of monocots. In agriculture the majority of the biomass produced comes from monocots and these include not only major grains, but also forage grasses, sugar cane, and the bamboos. Other economically important monocot crops include various palms, bananas, gingers and their relatives, turmeric and cardamom, asparagus and the onions and garlic family. Additionally most of the bulbs, plants cultivated for their blooms, such as lilies, daffodils, irises, amaryllis, cannas, bluebells. The monocots or monocotyledons have, as the name implies, a single cotyledon, or embryonic leaf, from a diagnostic point of view the number of cotyledons is neither a particularly useful characteristic, nor is it completely reliable. Nevertheless, monocots are sufficiently distinctive that there has rarely been disagreement as to membership of this group, however, morphological features that reliably characterise major clades are rare. Thus monocots are distinguishable from other angiosperms both in terms of their uniformity and diversity, although largely herbaceous, some arboraceous monocots reach great height, length and mass. The latter include agaves, palms, pandans, and bamboos and this creates challenges in water transport that monocots deal with in various ways. Some such as species of Yucca develop anomalous secondary growth, while palm trees, the axis undergoes primary thickening, that progresses from internode to internode, resulting in a typical inverted conical shape of the basal primary axis. The limited conductivity also contributes to limited branching of the stems, despite these limitations a wide variety of adaptive growth forms has resulted from epiphytic orchids and bromeliads to submarine Alismatales and mycotrophic Burmanniaceae and Triuridaceae. Other monocots, particularly Poales have adopted a life form. Leaves The cotyledon, the primordial Angiosperm leaf consists of a proximal leaf base or hypophyll, in moncots the hypophyll tends to be the dominant part in contrast to other angiosperms. Mature monocot leaves are narrow and linear, forming a sheathing around the stem at its base. There is usually only one leaf per node because the leaf base encompasses more than half the circumference, the evolution of this monocot characteristic has been attributed to developmental differences in early zonal differentiation rather than meristem activity

Commelinids
–
In plant taxonomy, commelinids is a name used by the APG III system for a clade within the monocots, which in its turn is a clade within the angiosperms. The commelinids are the clade that the APG has informally named within the monocots. The remaining monocots are a paraphyletic unit, also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch, the other two groups being the alismatid monocots and the lilioid monocots. Members of the clade have cell walls containing UV-fluorescent ferulic acid. The commelinids were first recognized as a group in 1967 by Armen Takhtajan. However, by the release of his 1980 system of classification, the commelinids constitute a well-supported clade within the monocots, and this clade has been recognized in all four APG classification systems. The commelinids of APG II and APG III contain essentially the same plants as the commelinoids of the earlier APG system, in APG IV the family Dasypogonaceae is no longer directly placed under commelinids but instead a family of order Arecales.

Zingiberales
–
The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots, together with its sister order, Commelinales. The order includes 68 genera and 2,600 species, Zingiberales are a unique though morphologically diverse order that has been widely recognised as such over a long period of time. Usually large herbaceous plants with rhizomatous root systems and lacking an aerial stem except when flowering, flowers are usually large and showy, and the stamens are often modified to also form colourful petal-like structures that attract pollinators. Zingiberales contain eight families that are considered as two groups, differing in the number of fertile stamens. A banana group of four families appeared first and were named on the basis of large banana like leaves, later, a more genetically coherent ginger group appeared, consisting of the remaining four families. Zingiberales are found throughout the tropics with some extension into subtropical and they rely on insects for pollination, together with some birds and small animals. The order includes many plants, and are used as ornamental plants, food crops, spices. Zingiberales are one of an ecologically and morphologically diverse and species rich order of monocots and they are large rhizomatous herbaceous plants but lacking an aerial stem, except when flowering. Leaves usually petiolate with distinct petiole and lamina, leaf arrangement distichous, venation pinnate-parallelodromous, with midrib, S-shaped lateral veins and fine transverse venation. Flowers are generally large and showy, following the general pattern, with inflorescences in thyrse-like spikes, zygomorphic to asymmetric. Gynoecium tricarpellate, ovary epigynous, two trimerous androecial whorls with stamens 6,5 or 1, stamens have elongated sterile filaments to which are attached anthers, distally, comprising about half of the length of the total stamen. For a brief history of the taxonomy of this order, see Scitamineae and they were first described by August Grisebach, their botanical authority, in 1854 as Zingiberides, an order of monocotyledons, subdivided into two families, Scitamineae and Musaceae. Later systems such as the Engler system and the Wettstein system and this usage was followed by Takhtajan within superorder Lilianae and by Dahlgren in its own superorder Zingiberiflorae. In contrast the Cronquist system retained Scitamineae as the name for this order with eight families and this was an ordinal system that did not examine subordinal structure. The order, which now has more than 2,600 species, in the Bentham and Hooker system, their Ordo Scitamineae had four tribes, Zingibereae, Maranteae, Canneae, and Museae. The APG II system provided a classification of families for the first time, family Cannaceae Juss. family Costaceae Nakai family Heliconiaceae Vines family Lowiaceae Ridl. family Marantaceae R. Br. family Musaceae Juss. family Strelitziaceae Hutch. A paraphyletic basal assemblage with 5 or 6 fertile stamens at maturity, in those with five stamina, the sixth may regress and be absent or develop as an infertile staminode. Petals and stamens are fused at the base to form a floral tube

Zingiberaceae
–
Many of the familys species are important ornamental, spice, or medicinal plants. Ornamental genera include the shell gingers, Siam or summer tulip, Globba, ginger lily, Kaempferia, torch-ginger Etlingera elatior, Renealmia, spices include ginger, galangal or Thai ginger, melegueta pepper, myoga, korarima, turmeric, and cardamom. Members of the family are small to large plants with distichous leaves with basal sheaths that overlap to form a pseudostem. The plants are either self-supporting or epiphytic, flowers are hermaphroditic, usually strongly zygomorphic, in determinate cymose inflorescences, and subtended by conspicuous, spirally arranged bracts. The perianth is composed of two whorls, a tubular calyx, and a tubular corolla with one lobe larger than the other two. Flowers typically have two of their stamenoids fused to form a lip, and have only one fertile stamen. The ovary is inferior and topped by two nectaries, the stigma is funnel-shaped, some genera yield essential oils used in the perfume industry. B. The University of North Carolina Press

Curcuma
–
Curcuma is a genus of about 100 accepted species in the family Zingiberaceae that contains such species as turmeric and Siam Tulip. They are native to Southeast Asia, southern China, the Indian Subcontinent, New Guinea, some species are reportedly naturalised in other warm parts of the world such as tropical Africa, Central America, Florida, and various islands of the Pacific, Indian and Atlantic Oceans. The name comes from Arabic kurkum meaning turmeric, since assembly of the genus Curcuma by Linnaeus in 1753 about 130 species have been described so far. Some of the descriptions are without Latin diagnosis or type specimen, therefore the legitimate status of many species is suspicious.

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

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

Rhizome
–
In botany and dendrology, a rhizome is a modified subterranean stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks and rootstocks, Rhizomes develop from axillary buds and are diageotropic or grow perpendicular to the force of gravity. The rhizome also retains the ability to new shoots to grow upwards. If a rhizome is separated into pieces, each piece may be able to rise to a new plant. The plant uses the rhizome to store starches, proteins, and these nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter. This is a known as vegetative reproduction and is used by farmers and gardeners to propagate certain plants. This also allows for lateral spread of grasses like bamboo and bunch grasses, examples of plants that are propagated this way include hops, asparagus, ginger, irises, Lily of the Valley, cannas, and sympodial orchids. Some rhizomes which are used directly in cooking include ginger, turmeric, galangal, stored rhizomes are subject to bacterial and fungal infections, making them unsuitable for replanting and greatly diminishing stocks. However, rhizomes can also be produced artificially from tissue cultures, the ability to easily grow rhizomes from tissue cultures leads to better stocks for replanting and greater yields. The plant hormones ethylene and jasmonic acid have found to help induce and regulate the growth of rhizomes. Ethylene that was applied externally was found to affect internal ethylene levels, knowledge of how to use these hormones to induce rhizome growth could help farmers and biologists producing plants grown from rhizomes more easily cultivate and grow better plants. The poplars are an example of trees that propagate using a rhizome, the Pando colony in Utah is a famous example, which has been living for about 80,000 years. In general, rhizomes have short internodes, they send out roots from the bottom of the nodes, a stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, for example, the common potato, the term tuber is often used imprecisely, and is sometimes applied to plants with rhizomes. Some plants have rhizomes that grow above ground or that lie at the surface, including some Iris species. Rhizomes generally form a layer, but in Giant Horsetails. Many rhizomes have culinary value, and some, such as zheergen, are consumed raw. Aspen Corm Mycorrhiza Media related to Rhizomes at Wikimedia Commons

Herbaceous plant
–
Herbaceous plants are plants that have no persistent woody stem above ground. Herbaceous plants may be annuals, biennials or perennials, annual herbaceous plants die completely at the end of the growing season or when they have flowered and fruited, and they then grow again from seed. Herbaceous perennial and biennial plants may have stems that die at the end of the growing season, but parts of the plant survive under or close to the ground from season to season. New growth develops from living tissues remaining on or under the ground, including roots, examples of herbaceous biennials include carrot, parsnip and common ragwort, herbaceous perennials include potato, peony, hosta, mint, most ferns and most grasses. Some relatively fast-growing herbaceous plants are pioneers, or early-successional species, others form the main vegetation of many stable habitats, occurring for example in the ground layer of forests, or in naturally open habitats such as meadow, salt marsh or desert. Some herbaceous plants can grow large, such as the Musa genus. The age of some herbaceous plants can be determined by analyzing annual growth rings in the secondary root xylem
15.
Perennial plant
–
A perennial plant or simply perennial is a plant that lives for more than two years. The term is used to differentiate a plant from shorter-lived annuals and biennials. The term is widely used to distinguish plants with little or no woody growth from trees and shrubs. Tomato vines, for example, live several years in their natural habitat but are grown as annuals in temperate regions because they dont survive the winter. There is also a class of evergreen, or non-herbaceous, perennials, an intermediate class of plants is known as subshrubs, which retain a vestigial woody structure in winter, e. g. Penstemon. The local climate may dictate whether plants are treated as shrubs or perennials, for instance, many varieties of Fuchsia are shrubs in warm regions, but in colder temperate climates may be cut to the ground every year as a result of winter frosts. The symbol for a plant, based on Species Plantarum by Linnaeus, is. Perennial plants can be short-lived or they can be long-lived, as are some plants like trees. They include an assortment of plant groups from ferns and liverworts to the highly diverse flowering plants like orchids. Plants that flower and fruit only once and then die are termed monocarpic or semelparous, however, most perennials are polycarpic, flowering over many seasons in their lifetime. Perennials typically grow structures that allow them to adapt to living one year to the next through a form of vegetative reproduction rather than seeding. These structures include bulbs, tubers, woody crowns, rhizomes plus others and they might have specialized stems or crowns that allow them to survive periods of dormancy over cold or dry seasons during the year. Many perennials have developed specialized features that allow them to extreme climatic. Some have adapted to hot and dry conditions or cold temperatures. Those plants tend to invest a lot of resource into their adaptations and often do not flower, Many perennials produce relatively large seeds, which can have an advantage, with larger seedlings produced after germination that can better compete with other plants. Some annuals produce many seeds per plant in one season, while some perennials are not under the same pressure to produce large numbers of seeds. In warmer and more favorable climates, perennials grow continuously, in seasonal climates, their growth is limited to the growing season. In some species, perennials retain their foliage all year round, other plants are deciduous perennials, for example, in temperate regions a perennial plant may grow and bloom during the warm part of the year, with the foliage dying back in the winter

Ginger
–
Ginger is a flowering plant whose rhizome, ginger root or simply ginger, is widely used as a spice or a folk medicine. It is a perennial which grows annual stems about a meter tall bearing narrow green leaves. Ginger is in the family Zingiberaceae, to also belong turmeric, cardamom. Ginger originated in the tropical rainforest in Southern Asia, although ginger no longer grows wild, it is thought to have originated on the Indian subcontinent because the ginger plants grown in India show the largest amount of genetic variation. Ginger was exported to Europe via India in the first century AD as a result of the spice trade and was used extensively by the Romans. The distantly related dicots in the genus Asarum are commonly called wild ginger because of their similar taste. But this may be Sanskrit folk etymology, and the word may be from an ancient Dravidian name that produced the Tamil and Malayalam name for the spice, inchi-ver. The word probably was readopted in Middle English from Old French gingibre, ginger produces clusters of white and pink flower buds that bloom into yellow flowers. Because of its appeal and the adaptation of the plant to warm climates. It is a perennial plant with annual leafy stems, about a meter tall. Traditionally, the rhizome is gathered when the stalk withers, it is scalded, or washed and scraped, to kill it. The fragrant perisperm of the Zingiberaceae is used as sweetmeats by Bantu, ginger produces a hot, fragrant kitchen spice. Young ginger rhizomes are juicy and fleshy with a mild taste. They are often pickled in vinegar or sherry as a snack or cooked as an ingredient in many dishes and they can be steeped in boiling water to make ginger tisane, to which honey is often added, sliced orange or lemon fruit may be added. Ginger can be made into candy, or ginger wine, which has been made commercially since 1740, mature ginger rhizomes are fibrous and nearly dry. Fresh ginger can be substituted for ground ginger at a ratio of six to one, although the flavors of fresh, powdered dry ginger root is typically used as a flavoring for recipes such as gingerbread, cookies, crackers and cakes, ginger ale, and ginger beer. Candied ginger, or crystallized ginger, is the root cooked in sugar until soft, fresh ginger may be peeled before eating. For longer-term storage, the ginger can be placed in a plastic bag, in Indian cuisine, ginger is a key ingredient, especially in thicker gravies, as well as in many other dishes, both vegetarian and meat-based

Indian subcontinent
–
Geologically, the Indian subcontinent is related to the land mass that rifted from Gondwana and merged with the Eurasian plate nearly 55 million years ago. Geographically, it is the region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west. Politically, the Indian subcontinent usually includes Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, sometimes, the term South Asia is used interchangeably with Indian subcontinent. There is no consensus about which countries should be included in each and it is first attested in 1845 to refer to the North and South Americas, before they were regarded as separate continents. Its use to refer to the Indian subcontinent is seen from the twentieth century. It was especially convenient for referring to the region comprising both the British India and the states under British Paramountcy. The term Indian subcontinent also has a geological significance and it was, like the various continents, a part of the supercontinent of Gondwana. A series of tectonic splits caused formation of basins, each drifting in various directions. The geological region called the Greater India once included the Madagascar, Seychelles, Antartica, as a geological term, Indian subcontinent has meant that region formed from the collision of the Indian basin with Eurasia nearly 55 million years ago, towards the end of Paleocene. The Indian subcontinent has been a particularly common in the British Empire. The region, state Mittal and Thursby, has also labelled as India, Greater India. The BBC and some sources refer to the region as the Asian Subcontinent. Some academics refer to it as South Asian Subcontinent, the terms Indian subcontinent and South Asia are sometimes used interchangeably. There is no accepted definition on which countries are a part of South Asia or Indian subcontinent. In dictionary entries, the term subcontinent signifies a large, distinguishable subdivision of a continent, the region experienced high volcanic activity and plate subdivisions, creating Madagascar, Seychelles, Antartica, Austrolasia and the Indian subcontinent basin. The Indian subcontinent drifted northeastwards, colliding with the Eurasian plate nearly 55 million years ago and this geological region largely includes Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. The zone where the Eurasian and Indian subcontinent plates meet remains one of the active areas. The English term mainly continues to refer to the Indian subcontinent, physiographically, it is a peninsular region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west, and the Arakanese in the east

Southeast Asia
–
Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China, east of India, west of New Guinea and north of Australia. The region lies near the intersection of geological plates, with seismic and volcanic activity. Southeast Asia consists of two regions, Mainland Southeast Asia, also known historically as Indochina, comprising Vietnam, Laos, Cambodia, Thailand, Myanmar. Maritime Southeast Asia, comprising Indonesia, East Malaysia, Singapore, Philippines, East Timor, Brunei, Cocos Islands, definitions of Southeast Asia vary, but most definitions include the area represented by the countries listed below. All of the states are members of the Association of Southeast Asian Nations, the area, together with part of South Asia, was widely known as the East Indies or simply the Indies until the 20th century. Sovereignty issues exist over some territories in the South China Sea, Papua New Guinea has stated that it might join ASEAN, and is currently an observer. Southeast Asia is geographically divided into two subregions, namely Mainland Southeast Asia and Maritime Southeast Asia, Mainland Southeast Asia includes, Maritime Southeast Asia includes, The Andaman and Nicobar Islands of India are geographically considered part of Southeast Asia. Eastern Bangladesh and the Seven Sister States of India are culturally part of Southeast Asia, the eastern half of Indonesia and East Timor are considered to be biogeographically part of Oceania. Homo sapiens reached the region by around 45,000 years ago, homo floresiensis also lived in the area up until 12,000 years ago, when they became extinct. Austronesian people, who form the majority of the population in Indonesia, Malaysia, Brunei, East Timor. Solheim and others have shown evidence for a Nusantao maritime trading network ranging from Vietnam to the rest of the archipelago as early as 5000 BC to 1 AD. The peoples of Southeast Asia, especially those of Austronesian descent, have been seafarers for thousands of years and their vessels, such as the vinta, were ocean-worthy. Magellans voyage records how much more manoeuvrable their vessels were, as compared to the European ships, Passage through the Indian Ocean aided the colonisation of Madagascar by the Austronesian people, as well as commerce between West Asia and Southeast Asia. Gold from Sumatra is thought to have reached as far west as Rome and this was later replaced by Hinduism. Theravada Buddhism soon followed in 525, in the 15th century, Islamic influences began to enter. This forced the last Hindu court in Indonesia to retreat to Bali, in Mainland Southeast Asia, Burma, Cambodia and Thailand retained the Theravada form of Buddhism, brought to them from Sri Lanka. This type of Buddhism was fused with the Hindu-influenced Khmer culture, very little is known about Southeast Asian religious beliefs and practices before the advent of Indian merchants and religious influences from the 2nd century BCE onwards. Prior to the 13th century CE, Hinduism and Buddhism were the religions in Southeast Asia

Climate of India
–
The climate of India comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalisations difficult. Many regions have different microclimates. The nation has four seasons, winter, summer, a rainy season. As Earths highest and most massive mountain range, the Himalayas bar the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia. Most of North India is thus kept warm or is only mildly chilly or cold during winter, though the Tropic of Cancer—the boundary between the tropics and subtropics—passes through the middle of India, the bulk of the country can be regarded as climatically tropical. There is one scientific opinion which states that in South Asia such climatic events are likely to change in unpredictability, frequency, during the Triassic period of some 251–199.6 Ma, the Indian subcontinent was part of a vast supercontinent known as Pangaea. India later merged into the southern supercontinent Gondwana, a process beginning some 550–500 Ma and this is underscored by Indias vast coal reserves—much of it from the late Paleozoic sedimentary sequence—the fourth-largest reserves in the world. During the Mesozoic, the world, including India, was warmer than today. With the coming of the Carboniferous, global cooling stoked extensive glaciation, which spread northwards from South Africa towards India, tectonic movement by the Indian Plate caused it to pass over a geologic hotspot—the Réunion hotspot—now occupied by the volcanic island of Réunion. This resulted in a flood basalt event that laid down the Deccan Traps some 60–68 Ma. This may have contributed to the global Cretaceous–Paleogene extinction event, which caused India to experience significantly reduced insolation, elevated atmospheric levels of sulphur gases formed aerosols such as sulphur dioxide and sulphuric acid, similar to those found in the atmosphere of Venus, these precipitated as acid rain. Elevated carbon dioxide emissions also contributed to the effect, causing warmer weather that lasted long after the atmospheric shroud of dust. Further climatic changes 20 million years ago, long after India had crashed into the Laurasian landmass, were enough to cause the extinction of many endemic Indian forms. The nations climate is influenced by the Himalayas and the Thar Desert. Simultaneously, the Thar Desert plays a role in attracting moisture-laden southwest summer monsoon winds that, four major climatic groupings predominate, into which fall seven climatic zones that, as designated by experts, are defined on the basis of such traits as temperature and precipitation. Groupings are assigned according to the Köppen climate classification system. A tropical rainy climate governs regions persistent to warm or high temperatures, India hosts two climatic subtypes- tropical monsoon climate, tropical wet and dry climate that fall under this group. 1) The most humid is the tropical wet climate—also known as a tropical monsoon climate—that covers a strip of southwestern lowlands abutting the Malabar Coast, the Western Ghats, Indias two island territories, Lakshadweep and the Andaman and Nicobar Islands, are also subject to this climate

Food coloring
–
Food coloring, or color additive, is any dye, pigment or substance that imparts color when it is added to food or drink. They come in many forms consisting of liquids, powders, gels, Food coloring is used both in commercial food production and in domestic cooking. Food colorants are used in a variety of non-food applications including cosmetics, pharmaceuticals, home craft projects. People associate certain colors with certain flavors, and the color of food can influence the flavor in anything from candy to wine. During the Middle Ages, the economy in the European countries was based on agriculture, under feudalism, aesthetic aspects were not considered, at least not by the vast majority of the generally very poor population. This situation changed with urbanization at the beginning of the Modern Age, one of the very first food laws, created in Augsburg, Germany, in 1531, concerned spices or colorants and required saffron counterfeiters to be burned. With the onset of the revolution, people became dependent on foods produced by others. These new urban dwellers demanded food at low cost, analytical chemistry was still primitive and regulations few. Copper arsenite was used to recolor used tea leaves for resale and it also caused two deaths when used to color a dessert in 1860. Again his tea if mixed or green, he would not escape without the administration of a little Prussian blue. Many color additives had never tested for toxicity or other adverse effects. Historical records show that injuries, even deaths, resulted from tainted colorants, in 1851, about 200 people were poisoned in England,17 of them fatally, directly as a result of eating adulterated lozenges. Originally, these were dubbed coal-tar colors because the materials were obtained from bituminous coal. Many synthesized dyes were easier and less costly to produce and were superior in coloring properties when compared to naturally derived alternatives, some synthetic food colorants are diazo dyes. Diazo dyes are prepared by coupling of a compound with a second aromatic hydrocarbons. The resulting compounds contain conjugated systems that absorb light in the visible parts of the spectrum. The attractiveness of the synthetic dyes is that their color, lipophilicity, the color of the dyes can be controlled by selecting the number of azo-groups and various substituents. Yellow shades are often achieved by using acetoacetanilide, Red colors are often azo compounds

Asian cuisines
–
Asian cuisine includes several major regional cuisines, East Asian, Southeast Asian, South Asian, Central Asian, and Middle Eastern. A cuisine is a style of cooking practices and traditions. Asia, being the largest and most populous continent, is home to many cultures, ingredients common to many cultures in the East and Southeast regions of the continent include rice, ginger, garlic, sesame seeds, chilies, dried onions, soy, and tofu. Stir frying, steaming, and deep frying are common cooking methods, while rice is common to most Asian cuisines, different varieties are popular in the various regions. Basmati rice is popular in the subcontinent, Jasmine rice is found across the southeast, while long-grain rice is popular in China and short-grain in Japan. Curry is a dish in southern, western and southeastern Asia. Curry dishes with origins in India and other South Asian countries usually have a base while Southeastern and Eastern curries generally use coconut milk as their foundation. East Asian cuisine includes Chinese, Japanese, Korean, Mongolian, considering this is the most populated region of the world, it has many regional cuisines. Examples of staple foods include rice, noodles, mung beans, soy beans, seafood, mutton, bok choy, and tea. Ingredients in the region contrast with the ones in the Eastern Asian cuisines, substituting fish sauces for soy sauce, cooking methods include a balance of stir-frying, boiling and steaming. South Asian cuisine, also known as Desi cuisine, includes the cuisines from the Indian subcontinent, foods in this area of the world are flavoured with various types of chili, black pepper, cloves, and other strong herbs and spices along with the flavoured butter and ghee. Turmeric and cumin are used to make curries. Common meats include lamb, goat, fish and chicken, beef is less common than in Western cuisines because cattle have a special place in Hinduism but it is highly popular in South India, especially among Christians and Muslims. Prohibitions against beef extend to the meat of buffalo and yaks to some extent, pork is considered a taboo food item by all Muslims and is avoided by most Hindus. Most Central Asian nations have similar cuisines to each other as well as their neighbors, taking many features of the cuisines of Western and Eastern Asia. A dish known as plov, or osh, for example, is a variation of pilaf. However, many of the countries use horse meat and mutton as the most common meats. This is owing to Mongolian cuisine, in Kazakhstan and Kyrgyzstan, cuisine has evolved to meet the needs of a nomad lifestyle

Curry
–
Curry is a dish originating in the cuisine of the Indian subcontinent. The common feature is the use of combinations of spices or herbs. The use of the term is limited to dishes prepared in a sauce. Curry dishes prepared in the states of India may be spiced with leaves from the curry tree. There are many varieties of dishes called curries, such dishes are called by specific names that refer to their ingredients, spicing, and cooking methods. Traditionally, spices are used whole and ground, cooked or raw, and they may be added at different times during the cooking process to produce different results. Curry powder, a commercially prepared mixture of spices, is largely a Western creation, such mixtures are commonly thought to have first been prepared by Indian merchants for sale to members of the British Colonial government and army returning to Britain. Dishes called curry may contain fish, meat, poultry, or shellfish, additionally, many instead are entirely vegetarian, eaten especially among those who hold ethical or religious proscriptions against eating meat or seafood. Curries may be dry or wet. Dry curries are cooked with very little liquid which is allowed to evaporate, wet curries contain significant amounts of sauce or gravy based on yoghurt, cream, coconut milk, coconut cream, legume purée, or broth. The first curry recipe in English was published in 1747 by Hannah Glasse, archaeological evidence dating to 2600 BCE from Mohenjo-daro suggests the use of mortar and pestle to pound spices including mustard, fennel, cumin, and tamarind pods with which they flavoured food. Black pepper is native to South Asia and Southeast Asia and has known to Indian cooking since at least 2000 BCE. The establishment of the Mughal Empire, in the early 16th century, influenced some curries, Curry was introduced to English cuisine starting with Anglo-Indian cooking in the 17th century as spicy sauces were added to bland boiled and cooked meats. The 1758 edition of Hannah Glasses The Art of Cookery contains a recipe To make a currey the Indian way, Curry was first served in coffee houses in Britain from 1809, and has been increasingly popular in Great Britain, with major jumps in the 1940s and the 1970s. During the 19th century, curry was also carried to the Caribbean by Indian indentured workers in the British sugar industry, since the mid-20th century, curries of many national styles have become popular far from their origins, and increasingly become part of international fusion cuisine. It is usual to distinguish broadly between northern and southern styles of Indian cuisine, recognising that within those categories are innumerable sub-styles and variations. The distinction is made with reference to the staple starch, wheat in the form of unleavened breads in the north, rice in the east, rice. Bengali cuisine, which refers to the cuisine of Bangladesh and the West Bengal state of India, includes curries, including seafood, Mustard seeds and mustard oil are added to many recipes, as are poppy seeds

Dye
–
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. Both dyes and pigments are colored because they absorb some wavelengths of light more than others, in contrast to dyes, pigments are insoluble and have no affinity for the substrate. Some dyes can be precipitated with a salt to produce a lake pigment. The majority of natural dyes are from plant sources, roots, berries, bark, leaves, and wood, fungi, textile dyeing dates back to the Neolithic period. Throughout history, people have dyed their textiles using common, locally available materials, scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes Tyrian purple and crimson kermes were highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad, indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia, across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of color in piece-dyed cloth. Dyes from the New World such as cochineal and logwood were brought to Europe by the Spanish treasure fleets, dyed flax fibers have been found in the Republic of Georgia in a prehistoric cave dated to 36,000 BP. Archaeological evidence shows that, particularly in India and Phoenicia, dyeing has been carried out for over 5,000 years. The dyes were obtained from animal, vegetable or mineral origin, by far the greatest source of dyes has been from the plant kingdom, notably roots, berries, bark, leaves and wood, but only a few have ever been used on a commercial scale. The discovery of synthetic dyes late in the 19th century ended the large-scale market for natural dyes. These dyes are made from synthetic resources such as petroleum by-products, the first human-made organic aniline dye, mauveine, was discovered serendipitously by William Henry Perkin in 1856, the result of a failed attempt at the total synthesis of quinine. Other aniline dyes followed, such as fuchsine, safranine, many thousands of synthetic dyes have since been prepared. These may be natural or synthetic, other than pigmentation, they have a range of applications including organic dye lasers, optical media and camera sensors. This is the basic classification Dyes are classified according to their solubility, acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber, acid dyes are not substantive to cellulosic fibers. Most synthetic food colors fall in this category, basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dye bath to help the uptake of the dye onto the fiber, basic dyes are also used in the coloration of paper

Black pepper
–
Black pepper is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning. When dried, the fruit is known as a peppercorn, when fresh and fully mature, it is approximately 5 millimetres in diameter, dark red, and, like all drupes, contains a single seed. Peppercorns, and the ground pepper derived from them, may be described simply as pepper, or more precisely as black pepper, green pepper, black pepper is native to south India and is extensively cultivated there and elsewhere in tropical regions. Currently, Vietnam is the worlds largest producer and exporter of pepper, dried ground pepper has been used since antiquity for both its flavour and as a traditional medicine. Black pepper is the worlds most traded spice and it is one of the most common spices added to cuisines around the world. The spiciness of black pepper is due to the chemical piperine, black pepper is ubiquitous in the modern world as a seasoning and is often paired with salt. The word pepper has its roots in the Tamil word for long pepper, todays pepper derives from the Old English pipor. and from Latin which was the source of Romanian piper, Italian pepe, Dutch peper, German Pfeffer, French poivre, and other similar forms. In the 16th century, pepper started referring to the unrelated New World chili pepper as well, Pepper was used in a figurative sense to mean spirit or energy at least as far back as the 1840s, in the early 20th century, this was shortened to pep. Black pepper is produced from the still-green, unripe drupes of the pepper plant. The drupes are cooked briefly in hot water, both to them and to prepare them for drying, the heat ruptures cell walls in the pepper. The drupes are dried in the sun or by machine for several days, during which the pepper around the seed shrinks and darkens into a thin, once dried, the spice is called black peppercorn. On some estates, the berries are separated from the stem by hand, once the peppercorns are dried, pepper spirit and oil can be extracted from the berries by crushing them. Pepper spirit is used in medicinal and beauty products. Pepper oil is used as an ayurvedic massage oil and used in certain beauty. White pepper consists solely of the seed of the pepper plant and this is usually accomplished by a process known as retting, where fully ripe red pepper berries are soaked in water for about a week, during which the flesh of the pepper softens and decomposes. Rubbing then removes what remains of the fruit, and the seed is dried. Sometimes alternative processes are used for removing the outer pepper from the seed, ground white pepper is used in Chinese and Thai cuisine, but also in salads, cream sauces, light-coloured sauces, and mashed potatoes. White pepper has a different flavour from black pepper, it lacks certain compounds present in the layer of the drupe
