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

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

Angiosperms
–
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

Anacardiaceae
–
The Anacardiaceae, commonly known as Cashew family, are a family of flowering plants commonly known as the cashew or sumac family, including about 83 genera with about 860 known species. Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, the Anacardiaceae include numerous genera, several of which are economically important, notably cashew, mango, poison ivy, sumac, smoke tree, marula, yellow mombin, and cuachalalate. The genus Pistacia is now included, but was placed in its own family. Trees or shrubs, each has inconspicuous flowers and highly poisonous, tannin sacs are also widespread among the family. The simple pits are located along the wall and in contact with the parenchyma. Leaves are deciduous or evergreen, usually alternate, estipulate and imparipinnate, usually with opposite leaflets, secondary venation is eucamptodromous, brochidodromous, craspedodromous or cladodromous Cladodromous venation, if present is considered diagnostic for Anacardiaceae. Flowers grow at the end of a branch or stem or at an angle from where the leaf joins the stem and have bracts. Often with this family, bisexual and male flowers occur on some plants, a calyx with three to seven cleft sepals and the same number of petals, occasionally no petals, overlap each other in the bud. Stamens are twice as many or equal to the number of petals, inserted at the base of the ring or cup-shaped disk. Stamen stalks are separate, and anthers are able to move, Flowers have the ovary free, but the petals and stamen are borne on the calyx. In the stamenate flowers, ovaries are single-celled, in the pistillate flowers, ovaries are single or sometimes quadri- or quinticelled. One to three styles and one ovule occur in each cavity, fruits rarely open at maturity and are most often drupes. Seed coats are very thin or are crust-like, little or no endosperm is present. Seeds are solitary with no albumen around the embryo, in 1759, Bernard de Jussieu arranged the plants in the royal garden of the Trianon at Versailles, according to his own scheme. That classification included a description of an order called the Terebintaceæ which contained a suborder that included Cassuvium, Anacardium, Mangifera, Connarus, Rhus, in 1789, Antoine Laurent de Jussieu, nephew of Bernard de Jussieu, published that classification scheme. The name and genera were based on the order with the name that had been described by Bernard de Jussieu in 1759. The herbarium from that expedition contained only one genus from the family, john Lindley described the Essential character of the Anacardiaceæ, the Cashew Tribe in 1831, adopting the order that was described by Jussieu, but abandoning the name Terebintaceæ. He includes the genera which were found in de Candolles Anacardieæ and Sumachineæ, Anacardium, Holigarna, Mangifera, Rhus and Mauria

Mangifera is a genus of flowering plants in the cashew family, Anacardiaceae. It contains approximately 69 species, with the best-known being the Common Mango, the center of diversity is in subtropical and tropical South Asia and Southeast Asia, while the highest number of species occur in India. They are generally canopy trees in rainforests, reaching a height of 30–40 m. Mangifera species are cultivated in Asia and elsewhere. More than 27 species in the genus bear edible, fleshy fruits, others, such as M. foetida, yield astringent fruits that can be eaten pickled. The earliest fossil species thought to be related to Mangifera is Eomangiferophyllum damalgiriense from the upper Paleocene of northeastern India, leaves have also been reported from the Paleocene of Japan and the Eocene of Germany. Leaf compressions with an affinity to Mangifera have been collected from Oligocene or early Miocene sediments in northern Thailand. Of these 10 are accepted species names

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

Drupe
–
In botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a shell of hardened endocarp with a seed inside. These fruits usually develop from a carpel, and mostly from flowers with superior ovaries. Other fleshy fruits may have an enclosure that comes from the seed coat surrounding the seed. The term drupaceous is applied to a fruit which has the structure and texture of a drupe, the boundary between a drupe and a berry is not always clear. Thus some sources describe the fruit of species of the genus Persea, one definition of berry requires the endocarp to be less than 2 mm thick, other fruits with a stony endocarp being drupes. In marginal cases, terms such as drupaceous or drupe-like may be used, the term stone fruit can be a synonym for drupe or, more typically, it can mean just the fruit of the genus Prunus. Freestone refers to a drupe having a stone which can be removed from the flesh with ease, the flesh is not attached to the stone and does not need to be cut to free the stone. Freestone varieties of fruits are preferred for uses that require removal of the stone. Freestone plums are preferred for making homegrown prunes, and freestone sour cherries are preferred for making pies, clingstone refers to a drupe having a stone which cannot easily be removed from the flesh. The flesh is attached strongly to the stone and must be cut to free the stone, clingstone varieties of fruits in the genus Prunus are preferred as table fruit and for jams, because the flesh of clingstone fruits tends to be more tender and juicy throughout. Tryma is a term for such nut-like drupes that are difficult to categorize. Hickory nuts and walnuts in the Juglandaceae family grow within a husk, these fruits are technically drupes or drupaceous nuts. Many drupes, with their sweet, fleshy outer layer, attract the attention of animals as a food, and the plant population benefits from the resulting dispersal of its seeds. The endocarp is sometimes dropped after the part is eaten, but is often swallowed, passing through the digestive tract. This passage through the tract can reduce the thickness of the endocarp. The process is known as scarification, typical drupes include apricots, olives, peaches, plums, cherries, mangoes and amlas. The coconut is also a drupe, but the mesocarp is fibrous or dry, so this type of fruit is classified as a simple dry, unlike other drupes, the coconut seed is unlikely to be dispersed by being swallowed by fauna, due to its large size. It can, however, float extremely long distances across oceans, bramble fruits are aggregates of drupelets

Tree
–
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a group but include a variety of plant species that have independently evolved a woody trunk. In looser senses, the palms, the tree ferns, bananas. Trees tend to be long-lived, some reaching several thousand years old, the tallest known tree, a coast redwood named Hyperion, stands 115.6 m high. Trees have been in existence for 370 million years and it is estimated that there are just over 3 trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk and this trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier, below the ground, the roots branch and spread out widely, they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the divide into smaller branches and shoots. The shoots typically bear leaves, which light energy and convert it into sugars by photosynthesis, providing the food for the trees growth. Flowers and fruit may also be present, but some trees, such as conifers, instead have pollen cones and seed cones, others, such as tree ferns, trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues, trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are one of the most biodiverse habitats in the world, trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In parts of the world, forests are shrinking as trees are cleared to increase the amount of available for agriculture. Because of their longevity and usefulness, trees have always revered, with sacred groves in various cultures. Although tree is a term of common parlance, there is no universally recognised precise definition of what a tree is, either botanically or in common language. In its broadest sense, a tree is any plant with the form of an elongated stem, or trunk. Trees are also defined by height, with smaller plants from 0.5 to 10 m being called shrubs

Cashew
–
The cashew tree is a tropical evergreen tree that produces the cashew nut and the cashew apple. It can grow as high as 14 m, but the dwarf cashew, growing up to 6 m, has proved profitable, with earlier maturity. The cashew nut, often called a cashew, is widely consumed. It is eaten on its own, used in recipes, or processed into cashew cheese or cashew butter, the shell of the cashew seed yields derivatives that can be used in many applications from lubricants to paints. The cashew apple is a reddish to yellow fruit, whose pulp can be processed into a sweet. The species is native to northeastern Brazil. Major production of cashews occurs in Vietnam, Nigeria, India and its English name derives from the Portuguese name for the fruit of the cashew tree caju, which itself is derived from the Tupian word acajú, literally meaning nut that produces itself. The generic name Anacardium, originally from the Greek, refers to the location of the seed outside the core or heart of the fruit. A mid-seventeenth century ethnographic painting by Albert Eckhout, who accompanied Dutch governor-general Johan Maurits, the cashew tree is large and evergreen, growing to 14 m tall, with a short, often irregularly shaped trunk. The leaves are arranged, leathery textured, elliptic to obovate, 4–22 cm long and 2–15 cm broad. The flowers are produced in a panicle or corymb up to 26 cm long, each flower is small, pale green at first, then turning reddish, with five slender, acute petals 7–15 mm long. The largest cashew tree in the covers a area around 7,500 m2, it is located in Natal, Rio Grande do Norte. The fruit of the tree is an accessory fruit. What appears to be the fruit is an oval or pear-shaped structure, a hypocarpium, that develops from the pedicel, called the cashew apple, better known in Central America as marañón, it ripens into a yellow and/or red structure about 5–11 cm long. It is edible, and has a sweet smell and a sweet taste. The pulp of the apple is very juicy, but the skin is fragile. The true fruit of the tree is a kidney or boxing-glove shaped drupe that grows at the end of the cashew apple. The drupe develops first on the tree, and then the pedicel expands to become the cashew apple, within the true fruit is a single seed, which is often considered a nut, in the culinary sense

South Asia

Topographically, it is dominated by the Indian Plate, which rises above sea level as Nepal and northern parts of India situated south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land by West Asia, Central Asia, East Asia, the current territories of Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, India, Pakistan, and Sri Lanka form the countries of South Asia. The South Asian Association for Regional Cooperation is an economic cooperation organisation in the region which was established in 1985, South Asia covers about 5.1 million km², which is 11. 51% of the Asian continent or 3. 4% of the worlds land surface area. The population of South Asia is about 1.749 billion or about one fourth of the worlds population, overall, it accounts for about 39. 49% of Asias population and is home to a vast array of peoples. The area of South Asia and its extent is not clear cut as systemic. Aside from the region of South Asia, formerly part of the British Empire, there is a high degree of variation as to which other countries are included in South Asia. Modern definitions of South Asia are consistent in including Afghanistan, India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Myanmar is included by some scholars in South Asia, but in Southeast Asia by others. Some do not include Afghanistan, others question whether Afghanistan should be considered a part of South Asia or the Middle East, the mountain countries of Nepal and Bhutan, and the island countries of Sri Lanka and Maldives are generally included as well. Myanmar is often added, and by various deviating definitions based on often substantially different reasons, the British Indian Ocean Territory, the common concept of South Asia is largely inherited from the administrative boundaries of the British Raj, with several exceptions. The Aden Colony, British Somaliland and Singapore, though administered at various times under the Raj, have not been proposed as any part of South Asia. Additionally Burma was administered as part of the Raj until 1937, the 562 princely states that were protected by but not directly ruled by the Raj became administrative parts of South Asia upon joining Union of India or Dominion of Pakistan. China and Myanmar have also applied for the status of members of SAARC. This bloc of countries include two independent countries that were not part of the British Raj – Nepal, and Bhutan, Afghanistan was a British protectorate from 1878 until 1919, after the Afghans lost to the British in the Second Anglo-Afghan war. The United Nations Statistics Divisions scheme of sub-regions include all eight members of the SAARC as part of Southern Asia, population Information Network includes Afghanistan, Bangladesh, Burma, India, Nepal, Pakistan and Sri Lanka as part of South Asia. Maldives, in view of its characteristics, was admitted as a member Pacific POPIN subregional network only in principle, the Hirschman–Herfindahl index of the United Nations Economic and Social Commission for Asia and the Pacific for the region includes only the original seven signatories of SAARC. The British Indian Ocean Territory is connected to the region by a publication of Janes for security considerations, the inclusion of Myanmar in South Asia is without consensus, with many considering it a part of southeast Asia and others including it within South Asia. Afghanistan was of importance to the British colonial empire, especially after the Second Anglo-Afghan War over 1878–1880, Afghanistan remained a British protectorate until 1919, when a treaty with Vladimir Lenin included the granting of independence to Afghanistan. Following Indias partition, Afghanistan has generally included in South Asia

Mangifera indica, commonly known as mango, is a species of flowering plant in the sumac and poison ivy family Anacardiaceae. It is found in the wild in Bangladesh, India and Pakistan where it is indigenous and it is a large fruit-tree, capable of a growing to a height and crown width of about 100 feet and trunk circumference of more than twelve feet. The species appears to have been domesticated in India at around 2000 BC, the species was brought to East Asia around 400-500 BCE from India, next, in the 15th century to the Philippines, and then, in the 16th century to Africa and Brazil by the Portuguese. The species was described for science by Linnaeus in 1753, Mango is the National fruit of India, Pakistan and the Philippines. The Mango tree is the tree of Bangladesh. It finds mention in the songs of 4th century CE Sanskrit poet Kalidasa, prior to that, it is believed to have been tasted by Alexander and Chinese pilgrim Hieun Tsang. Later in 16th century Mughal Emperor, Akbar planted 100,000 mango trees in Darbhanga, mangiferin is extracted from mango at high concentrations from the young leaves, bark, and from old leaves. Allergenic urushiols are present in the peel and can trigger contact dermatitis in sensitised individuals. This reaction is likely to occur in people who have been exposed to other plants from the Anacardiaceae family, such as poison oak and poison ivy. In Ayurveda, it is used in a Rasayana formula sometimes with other mild sours and shatavari, in this oriental system of traditional medicine, varied properties are attributed to different parts of the mango tree, both as food and medicine. Extracts of the bark, leaves, stems, and unripe fruits have demonstrated antibiotic properties in vitro, the tree is more known for its fruit rather than for its lumber. However, mango trees can be converted to lumber once their fruit bearing lifespan has finished, the wood is susceptible to damage from fungi and insects. The wood is used for instruments such as ukuleles, plywood. The wood is known to produce phenolic substances that can cause contact dermatitis. In Theravada Buddhism, mango is said to have used as the tree for achieved enlightenment, the plant is known as අඹ in Sinhala. Author Pablo Antonio Cuadra, created a narrative of the Mango in Nicaragua, a single sapling that was placed on a ship in Hindustan and planted in a garden in Granada. Nicaragua is known for its many mangos, rivas, Nicaragua is known as La Ciudad de Los Mangos, which translates to the City of Mangoes.

Fruit
–
In botany, a fruit is the seed-bearing structure in flowering plants formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate seeds, accordingly, fruits account for a substantial fraction of the worlds agricultural output, and some have acquired extensive cultural and symbolic meanings. On the other hand, in usage, fruit includes many structures that are not commonly called fruits, such as bean pods, corn kernels, tomatoes. The section of a fungus that produces spores is called a fruiting body. Many common terms for seeds and fruit do not correspond to the botanical classifications, however, in botany, a fruit is the ripened ovary or carpel that contains seeds, a nut is a type of fruit and not a seed, and a seed is a ripened ovule. Examples of culinary vegetables and nuts that are botanically fruit include corn, cucurbits, eggplant, legumes, sweet pepper, in addition, some spices, such as allspice and chili pepper, are fruits, botanically speaking. g. Botanically, a grain, such as corn, rice, or wheat, is also a kind of fruit. However, the wall is very thin and is fused to the seed coat. The outer, often edible layer, is the pericarp, formed from the ovary and surrounding the seeds, the pericarp may be described in three layers from outer to inner, the epicarp, mesocarp and endocarp. Fruit that bears a prominent pointed terminal projection is said to be beaked, a fruit results from maturation of one or more flowers, and the gynoecium of the flower forms all or part of the fruit. Inside the ovary/ovaries are one or more ovules where the megagametophyte contains the egg cell, after double fertilization, these ovules will become seeds. The ovules are fertilized in a process starts with pollination. After pollination, a tube grows from the pollen through the stigma into the ovary to the ovule, later the zygote will give rise to the embryo of the seed, and the endosperm mother cell will give rise to endosperm, a nutritive tissue used by the embryo. As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, in some multiseeded fruits, the extent to which the flesh develops is proportional to the number of fertilized ovules. The pericarp is often differentiated into two or three distinct layers called the exocarp, mesocarp, and endocarp, in some fruits, especially simple fruits derived from an inferior ovary, other parts of the flower, fuse with the ovary and ripen with it. In other cases, the sepals, petals and/or stamens and style of the fall off. When such other floral parts are a significant part of the fruit, it is called an accessory fruit, since other parts of the flower may contribute to the structure of the fruit, it is important to study flower structure to understand how a particular fruit forms. There are three modes of fruit development, Apocarpous fruits develop from a single flower having one or more separate carpels

Tropics
–
The tropics are a region of the Earth surrounding the equator. The tropics are also referred to as the zone and the torrid zone. The tropics include all the areas on the Earth where the Sun is at a point directly overhead at least once during the solar year. The tropics are distinguished from the climatic and biomatic regions of Earth, which are the middle latitudes. Tropical is sometimes used in a sense for a tropical climate to mean warm to hot and moist year-round. Many tropical areas have a dry and wet season, the wet season, rainy season or green season, is the time of year, ranging from one or more months, when most of the average annual rainfall in a region falls. Areas with wet seasons are disseminated across portions of the tropics and subtropics, under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is 60 millimetres or more. Tropical rainforests technically do not have dry or wet seasons, since their rainfall is distributed through the year. When the wet season occurs during the season, or summer, precipitation falls mainly during the late afternoon. The wet season is a time when air quality improves, freshwater quality improves and vegetation grows significantly, floods cause rivers to overflow their banks, and some animals to retreat to higher ground. Soil nutrients diminish and erosion increases, the incidence of malaria increases in areas where the rainy season coincides with high temperatures. Animals have adaptation and survival strategies for the wetter regime, unfortunately, the previous dry season leads to food shortages into the wet season, as the crops have yet to mature. Regions within the tropics may well not have a tropical climate, there are alpine tundra and snow-capped peaks, including Mauna Kea, Mount Kilimanjaro, and the Andes as far south as the northernmost parts of Chile and Argentina. Under the Köppen climate classification, much of the area within the tropics is classed not as tropical but as dry including the Sahara Desert. Tropical plants and animals are those native to the tropics. Tropical ecosystems may consist of rainforests, dry forests, spiny forests, desert. There are often significant areas of biodiversity, and species present, particularly in rainforests. In biogeography, the tropics are divided into Paleotropics and Neotropics, together, they are sometimes referred to as the Pantropic

India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

The Philippines, officially the Republic of the Philippines, is a sovereign island country in Southeast Asia situated in the western Pacific Ocean. It consists of about 7,641 islands that are categorized broadly under three main geographical divisions from north to south, Luzon, Visayas, and Mindanao, the capital city of the Philippines is Manila and the most populous city is Quezon City, both part of Metro Manila. The Philippines has an area of 300,000 square kilometers, and it is the eighth-most populated country in Asia and the 12th most populated country in the world. As of 2013, approximately 10 million additional Filipinos lived overseas, multiple ethnicities and cultures are found throughout the islands. In prehistoric times, Negritos were some of the archipelagos earliest inhabitants and they were followed by successive waves of Austronesian peoples. Exchanges with Chinese, Malay, Indian, and Islamic nations occurred, then, various competing maritime states were established under the rule of Datus, Rajahs, Sultans or Lakans. The arrival of Ferdinand Magellan in Homonhon, Eastern Samar in 1521 marked the beginning of Hispanic colonization, in 1543, Spanish explorer Ruy López de Villalobos named the archipelago Las Islas Filipinas in honor of Philip II of Spain. With the arrival of Miguel López de Legazpi from Mexico City, in 1565, the Philippines became part of the Spanish Empire for more than 300 years. This resulted in Roman Catholicism becoming the dominant religion, during this time, Manila became the western hub of the trans-Pacific trade connecting Asia with Acapulco in the Americas using Manila galleons. Aside from the period of Japanese occupation, the United States retained sovereignty over the islands until after World War II, since then, the Philippines has often had a tumultuous experience with democracy, which included the overthrow of a dictatorship by a non-violent revolution. It is a member of the United Nations, World Trade Organization, Association of Southeast Asian Nations, the Asia-Pacific Economic Cooperation forum. It also hosts the headquarters of the Asian Development Bank, the Philippines was named in honor of King Philip II of Spain. Spanish explorer Ruy López de Villalobos, during his expedition in 1542, named the islands of Leyte, eventually the name Las Islas Filipinas would be used to cover all the islands of the archipelago. Before that became commonplace, other such as Islas del Poniente. The official name of the Philippines has changed several times in the course of its history, during the Philippine Revolution, the Malolos Congress proclaimed the establishment of the República Filipina or the Philippine Republic. From the 1898 Treaty of Paris, the name Philippines began to appear, since the end of World War II, the official name of the country has been the Republic of the Philippines. The metatarsal of the Callao Man, reliably dated by uranium-series dating to 67,000 years ago is the oldest human remnant found in the archipelago to date and this distinction previously belonged to the Tabon Man of Palawan, carbon-dated to around 26,500 years ago. Negritos were also among the archipelagos earliest inhabitants, but their first settlement in the Philippines has not been reliably dated, there are several opposing theories regarding the origins of ancient Filipinos

Bangladesh, officially the Peoples Republic of Bangladesh, is a country in South Asia. It shares land borders with India and Myanmar, Nepal, Bhutan and China are located near Bangladesh but do not share a border with it. The countrys maritime territory in the Bay of Bengal is roughly equal to the size of its land area, Bangladesh is the worlds eighth most populous country. Dhaka is its capital and largest city, followed by Chittagong which has the countrys largest port, Bangladesh forms the largest and eastern part of the Bengal region. Bangladeshis include people of different ethnic groups and religions, Bengalis, who speak the official Bengali, make up 98% of the population. The politically dominant Bengali Muslims make the nation the worlds third largest Muslim-majority country, most of Bangladesh is covered by the Bengal delta, the largest delta on Earth. The country has 700 rivers and 8,046 km of inland waterways, highlands with evergreen forests are found in the northeastern and southeastern regions of the country. Bangladesh has many islands and a coral reef and it is home to the Sundarbans, the largest mangrove forest in the world. The countrys biodiversity includes a vast array of plant and wildlife, including critically endangered Bengal tigers, the Greeks and Romans identified the region as Gangaridai, a powerful kingdom of the historical subcontinent, in the 3rd century BCE. Archaeological research has unearthed several ancient cities in Bangladesh, which had trade links for millennia. The Bengal Sultanate and Mughal Bengal transformed the region into a cosmopolitan Islamic imperial power between the 14th and 18th centuries, the region was home to many principalities which had inland naval prowess. It was also a center of the worldwide muslin and silk trade. As part of British India, the region was influenced by the Bengali renaissance, the Partition of British India made East Bengal a part of the Dominion of Pakistan, and was renamed as East Pakistan. The region witnessed the Bengali Language Movement in 1952 and the Bangladesh Liberation War in 1971, after independence, a parliamentary republic was established. A presidential government was in place between 1975 and 1990, followed by a return to parliamentary democracy, the country has also been affected by poverty, natural disasters, hunger, dominant party systems and military coups. Bangladesh is a power and a major developing nation. Listed as one of the Next Eleven, it has the 46th largest economy and it is one of the largest textile exporters in the world. Its major trading partners are the European Union, the United States, China, India, Japan, Malaysia, with its strategically vital location between Southern, Eastern and Southeast Asia, Bangladesh is an important promoter of regional connectivity and cooperation

Kerala

Kerala historically known as Keralam, is an Indian state in South India on the Malabar Coast. It was formed on 1 November 1956 following the States Reorganisation Act by combining Malayalam-speaking regions, spread over 38,863 km2, it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33,387,677 inhabitants as per the 2011 Census, Malayalam is the most widely spoken language and is also the official language of the state. The region has been a prominent spice exporter since 3000 BCE, the Chera Dynasty was the first prominent kingdom based in Kerala, though it frequently struggled against attacks by the neighbouring Cholas and Pandyas. In the 15th century, the spice trade attracted Portuguese traders to Kerala, after independence, Travancore and Cochin joined the Republic of India and Travancore-Cochin was given the status of a state in 1949. In 1956, Kerala state was formed by merging Malabar district, Travancore-Cochin, Hinduism is practised by more than half of the population, followed by Islam and Christianity. The culture is a synthesis of Aryan and Dravidian cultures, developed over millennia, under influences from other parts of India, the production of pepper and natural rubber contributes significantly to the total national output. In the agricultural sector, coconut, tea, coffee, cashew, the states coastline extends for 595 kilometres, and around 1.1 million people in the state are dependent on the fishery industry which contributes 3% to the states income. The state has the highest media exposure in India with newspapers publishing in nine languages, mainly English, Kerala is one of the prominent tourist destinations of India, with backwaters, beaches, Ayurvedic tourism and tropical greenery as its major attractions. The name Kerala has an uncertain etymology, One popular theory derives Kerala from Kera and alam is land, thus land of coconuts, this also happens to be a nickname for the state due to abundance of coconut trees and its use by the locals. The word Kerala is first recorded in a 3rd-century BCE rock inscription left by the Maurya emperor Ashoka, the inscription refers to the local ruler as Keralaputra, or son of Chera. This contradicts the theory that Kera is from coconut tree, at that time, one of three states in the region was called Cheralam in Classical Tamil, Chera and Kera are variants of the same word. The word Cheral refers to the oldest known dynasty of Kerala kings and is derived from the Proto-Tamil-Malayalam word for lake, the earliest Sanskrit text to mention Kerala is the Aitareya Aranyaka of the Rigveda. It is also mentioned in the Ramayana and the Mahabharata, the two Hindu epics, the Skanda Purana mentions the ecclesiastical office of the Thachudaya Kaimal who is referred to as Manikkam Keralar, synonymous with the deity of the Koodalmanikyam temple. Keralam may stem from the Classical Tamil cherive-alam or chera alam, the Greco-Roman trade map Periplus Maris Erythraei refers to Keralaputra as Celobotra. According to Hindu mythology, the lands of Kerala were recovered from the sea by the warrior sage Parasurama. Parasurama threw his axe across the sea, and the water receded as far as it reached, according to legend, this new area of land extended from Gokarna to Kanyakumari. The land which rose from sea was filled with salt and unsuitable for habitation, so Parasurama invoked the Snake King Vasuki, out of respect, Vasuki and all snakes were appointed as protectors and guardians of the land

Taproot
–
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, dicots, one of the two divisions of angiosperms, start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most often replaced later in the development by a fibrous root system. A persistent taproot system forms when the radicle keeps growing and smaller lateral roots form along the taproot. The shape of taproots can vary but the typical shapes include, Conical root, fusiform root, this root is widest in the middle and tapers towards the top and the bottom, e. g. radish. Napiform root, the root has a top-like appearance and it is very broad at the top and tapers suddenly like a tail at the bottom, e. g. turnip. Many taproots are modified into storage organs and it branches off to secondary roots, which in turn branch to form tertiary roots. These may further branch to form rootlets, for most plants species the radicle dies some time after seed germination, causing the development of a fibrous root system, which lacks a main downward-growing root. A typical mature tree 30–50 m tall has a system that extends horizontally in all directions as far as the tree is tall or more. Increases photosynthesis and the evaporation of water, by 40 percent in the dry season. During the wet season, these plants can store as much as 10 percent of the precipitation as deep as 13 meters underground. Tree roots acting like pipes to water to shift around much faster than it could otherwise percolate through the soil

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

Evergreen
–
In botany, an evergreen is a plant that has leaves throughout the year, always green. This contrasts with deciduous plants, which lose their foliage during the winter or dry season. There are many different kinds of plants, both trees and shrubs. Deciduous trees shed their leaves, usually as an adaptation to a cold or dry/wet season, evergreen trees do lose leaves, but each tree loses its leaves gradually and not all at once. Most warm temperate climate plants are also evergreen, in cool temperate climates, fewer plants are evergreen, with a predominance of conifers, as few evergreen broadleaf plants can tolerate severe cold below about −30 °C. In areas where there is a reason for being deciduous, being evergreen is usually an adaptation to low nutrient levels, deciduous trees lose nutrients whenever they lose their leaves. In warmer areas, species such as pines and cypresses grow on poor soils. In Rhododendron, a genus with many broadleaf evergreens, several species grow in forests but are usually found on highly acidic soil where the nutrients are less available to plants. In taiga or boreal forests, it is too cold for the matter in the soil to decay rapidly, so the nutrients in the soil are less easily available to plants. These conditions favour the growth of more evergreens and make it difficult for deciduous plants to persist. In addition, the shelter provided by existing evergreen plants can make it easier for younger evergreen plants to survive cold and/or drought

Flower

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs, Flowers may facilitate outcrossing or allow selfing. Some flowers produce diaspores without fertilization, Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds, the essential parts of a flower can be considered in two parts, the vegetative part, consisting of petals and associated structures in the perianth, and the reproductive or sexual parts. A stereotypical flower consists of four kinds of structures attached to the tip of a short stalk, each of these kinds of parts is arranged in a whorl on the receptacle. The four main whorls are as follows, Collectively the calyx, corolla, the next whorl toward the apex, composed of units called petals, which are typically thin, soft and colored to attract animals that help the process of pollination. Androecium, the whorl, consisting of units called stamens. Stamens consist of two parts, a called a filament, topped by an anther where pollen is produced by meiosis. Gynoecium, the innermost whorl of a flower, consisting of one or more units called carpels, the carpel or multiple fused carpels form a hollow structure called an ovary, which produces ovules internally. Ovules are megasporangia and they in turn produce megaspores by meiosis which develop into female gametophytes and these give rise to egg cells. The gynoecium of a flower is described using an alternative terminology wherein the structure one sees in the innermost whorl is called a pistil. A pistil may consist of a carpel or a number of carpels fused together. The sticky tip of the pistil, the stigma, is the receptor of pollen, the supportive stalk, the style, becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma. The relationship to the gynoecium on the receptacle is described as hypogynous, perigynous, although the arrangement described above is considered typical, plant species show a wide variation in floral structure. These modifications have significance in the evolution of flowering plants and are used extensively by botanists to establish relationships among plant species, the four main parts of a flower are generally defined by their positions on the receptacle and not by their function. Many flowers lack some parts or parts may be modified into other functions and/or look like what is typically another part, in some families, like Ranunculaceae, the petals are greatly reduced and in many species the sepals are colorful and petal-like. Other flowers have modified stamens that are petal-like, the flowers of Peonies and Roses are mostly petaloid stamens

Panicle
–
A panicle is a much-branched inflorescence. Some authors distinguish it from a spike, by requiring that the flowers be pedicellate. The branches of a panicle are often racemes, a panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of such as oat and crabgrass, as well as other plants such as pistachio. Botanists use the term paniculate in two ways, having a true panicle inflorescence as well as having an inflorescence with the form but not necessarily the structure of a panicle. A corymb may have a branching structure, with the lower flowers having longer pedicels than the upper. Many species in the Maloideae, such as hawthorns and rowans, thyrse, a branched inflorescence where the main axis has indeterminate growth, and the branches have determinate growth

It is possibly the only species in the genus Convallaria. In the APG III system, the genus is placed in the family Asparagaceae and it was formerly placed in its own family Convallariaceae, and, like many lilioid monocots, before that in the lily family Liliaceae. Convallaria majalis is a perennial plant that forms extensive colonies by spreading underground stems called rhizomes. New upright shoots are formed at the ends of stolons in summer and these grow in the spring into new leafy shoots that still remain connected to the other shoots under ground, often forming extensive colonies. The stems grow to 15–30 cm tall, with one or two leaves 10–25 cm long, flowering stems have two leaves and a raceme of 5–15 flowers on the stem apex. The fruit is a small orange-red berry 5–7 mm diameter that contains a few large whitish to brownish colored seeds that dry to a clear translucent round bead 1–3 mm wide, plants are self-sterile, and colonies consisting of a single clone do not set seed. Convallaria majalis is a native of Europe, where it avoids the Mediterranean. An eastern variety, C. majalis var. manschurica occurs in Japan, a limited native population of C. majalis var. montana occurs in the Eastern United States. There is, however, some debate as to the status of the American variety. Like many perennial flowering plants, C. majalis exhibits dual reproductive modes by producing offspring asexually by vegetative means, Convallaria majalis is a plant of partial shade, and mesophile type that prefers warm summers. It likes soils that are silty or sandy and acid to moderately alkaline, the Royal Horticultural Society states that slightly alkaline soils are the most favoured. It is an Euroasiatic and suboceanic species that lives in mountains up to 1,500 m altitude, Convallaria majalis is used as a food plant by the larvae of some Lepidoptera species including the grey chi. Adults and larvae of the leaf beetle Lilioceris merdigera are also able to tolerate the cardenolides, there are three varieties that have sometimes been separated out as distinct species or subspecies by some botanists. It has gained the Royal Horticultural Societys Award of Garden Merit, in favourable conditions it can form large colonies. Various kinds and cultivars are grown, including those with flowers, rose-colored flowers, variegated foliage. C. majalis Rosea sometimes found under the name C. majalis var. rosea, has pink flowers, traditionally Convallaria majalis has been grown in pots and winter forced to provide flowers during the winter months, both for as potted plants and as cut flowers. All parts of the plant are poisonous, including the red berries which may be attractive to children. If ingested—even in small amounts—the plant can cause pain, vomiting, reduced heart rate, blurred vision, drowsiness

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

Fibre

Fiber or fibre is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials, the strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Natural fibers develop or occur in the shape, and include those produced by plants, animals. Plant fibers are employed in the manufacture of paper and textile, wood fiber, distinguished from vegetable fiber, is from tree sources. Forms include groundwood, lacebark, thermomechanical pulp, and bleached or unbleached kraft or sulfite pulps, animal fibers consist largely of particular proteins. Instances are silkworm silk, spider silk, sinew, catgut, wool, sea silk and hair such as wool, mohair and angora, fur such as sheepskin, rabbit, mink, fox, beaver. Mineral fibers include the asbestos group, asbestos is the only naturally occurring long mineral fiber. Six minerals have been classified as asbestos including chrysotile of the serpentine class, short, fiber-like minerals include wollastonite and palygorskite. Instances are collagen family of proteins, tendon, muscle proteins like actin, cell proteins like microtubules and many others, spider silk, sinew, man-made or chemical fibers are fibers whose chemical composition, structure, and properties are significantly modified during the manufacturing process. Man-made fibers consist of regenerated fibers and synthetic fibers, the earliest semi-synthetic fiber is the cellulose regenerated fiber, rayon. Most semi-synthetic fibers are cellulose regenerated fibers, cellulose fibers are a subset of man-made fibers, regenerated from natural cellulose. The cellulose comes from sources, rayon from tree wood fiber, Modal from beech trees, bamboo fiber from bamboo, seacell from seaweed. In the production of fibers, the cellulose is reduced to a fairly pure form as a viscous mass. Therefore, the process leaves few characteristics distinctive of the natural source material in the finished products. Some examples are, rayon bamboo fiber Lyocell, a brand of rayon Modal, historically, cellulose diacetate and -triacetate were classified under the term rayon, but are now considered distinct materials. Synthetic come entirely from materials such as petrochemicals, unlike those man-made fibers derived from such natural substances as cellulose or protein. Metallic fibers can be drawn from ductile metals such as copper, gold or silver and extruded or deposited from more brittle ones, such as nickel, carbon fibers are often based on oxydized and via pyrolysis carbonized polymers like PAN, but the end product is almost pure carbon. Silicon carbide fibers, where the polymers are not hydrocarbons but polymers

Resin
–
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. They are often mixtures of compounds, principally terpenes. Many plants, particularly woody plants, produce resin in response to injury, the resin acts as a bandage protecting the plant from invading insects and pathogens. Plants secrete resins and rosins for their protective benefits, the resin produced by most plants is composed mainly of terpenes and derivatives. Some resins also contain a proportion of resin acids. The individual components of resin can be separated by fractional distillation, rosins on the other hand are less volatile and consist, inter alia, of diterpenes. Amber is fossil resin from coniferous and other tree species, copal, kauri gum, dammar and other resins may also be found as subfossil deposits. Subfossil copal can be distinguished from genuine fossil amber because it becomes tacky when a drop of a solvent such as acetone or chloroform is placed on it, african copal and the kauri gum of New Zealand are also procured in a semi-fossil condition. Solidified resin from which the volatile terpene components have been removed by distillation is known as rosin, typical rosin is a transparent or translucent mass, with a vitreous fracture and a faintly yellow or brown colour, non-odorous or having only a slight turpentine odor and taste. Rosin is insoluble in water, mostly soluble in alcohol, essential oils, ether and hot fatty oils, and softens and melts under the influence of heat, rosin consists of a complex mixture of different substances including organic acids named the resin acids. These are closely related to the terpenes, and derive from them through partial oxidation, Resin acids can be dissolved in alkalis to form resin soaps, from which the purified resin acids are regenerated by treatment with acids. Examples of resin acids are abietic acid, C20H30O2, plicatic acid contained in cedar, and pimaric acid, C20H30O2, a constituent of galipot resin. Abietic acid can also be extracted from rosin by means of hot alcohol, it crystallizes in leaflets, pimaric acid closely resembles abietic acid into which it passes when distilled in a vacuum, it has been supposed to consist of three isomers. Rosin is obtained from pines and some plants, mostly conifers. Propolis, consisting largely of resins collected from such as poplars and conifers, is used by honey bees to seal gaps in their hives. Shellac and lacquer are examples of insect-derived resins, asphaltite and Utah resin are petroleum bitumens, not a product secreted by plants, although it was ultimately derived from plants. These were highly prized substances, and required as incense in religious rites. The word resin has been applied in the world to nearly any component of a liquid that will set into a hard lacquer or enamel-like finish

Seed
–
A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the coat from the integuments of the ovule. Seed plants now dominate biological niches on land, from forests to both in hot and cold climates. The term seed also has a meaning that antedates the above—anything that can be sown, e. g. seed potatoes. In the case of sunflower and corn seeds, what is sown is the seed enclosed in a shell or husk, many structures commonly referred to as seeds are actually dry fruits. Plants producing berries are called baccate, sunflower seeds are sometimes sold commercially while still enclosed within the hard wall of the fruit, which must be split open to reach the seed. Different groups of plants have other modifications, the stone fruits have a hardened fruit layer fused to. Nuts are the one-seeded, hard-shelled fruit of plants with an indehiscent seed. Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms from the gymnosperms, angiosperm seeds are produced in a hard or fleshy structure called a fruit that encloses the seeds, hence the name. Some fruits have layers of hard and fleshy material. In gymnosperms, no special structure develops to enclose the seeds, however, the seeds do become covered by the cone scales as they develop in some species of conifer. Seed production in natural plant populations varies widely from year-to-year in response to weather variables, insects and diseases, over a 20-year period, for example, forests composed of loblolly pine and shortleaf pine produced from 0 to nearly 5 million sound pine seeds per hectare. Over this period, there were six bumper, five poor, and nine good seed crops, right after fertilization, the zygote is mostly inactive, but the primary endosperm divides rapidly to form the endosperm tissue. This tissue becomes the food the young plant will consume until the roots have developed after germination, after fertilization the ovules develop into the seeds. The ovule consists of a number of components, The funicle or seed stalk which attaches the ovule to the placenta and hence ovary or fruit wall, the nucellus, the remnant of the megasporangium and main region of the ovule where the megagametophyte develops. The micropyle, a pore or opening in the apex of the integument of the ovule where the pollen tube usually enters during the process of fertilization. The chalaza, the base of the ovule opposite the micropyle, the shape of the ovules as they develop often affects the final shape of the seeds

Recalcitrant seed
–
Recalcitrant seeds are seeds that do not survive drying and freezing during ex-situ conservation and vice versa. By and large, these seeds cannot resist the effects of drying or temperatures less than 10 °C, thus, generally speaking, most tropical pioneer species have orthodox seeds but many climax species have recalcitrant or intermediate seeds. These seeds showed deterioration of cell membrane lipids and proteins after as few as 3–4 days of drying, other seeds such as those of the sweet chestnut show oxidative damage resulting from uncontrolled metabolism occurring during the drying process.

Michael Boym
–
Michał Piotr Boym was a Polish Jesuit missionary to China, scientist and explorer. He is notable as one of the first westerners to travel within the Chinese mainland, Michał Boym was born in Lwów, Poland, around 1614, to a well-off family of Hungarian ancestry. His grandfather Jerzy Boim came to Poland from Hungary with the king Stefan Batory, Michałs father, Paweł Jerzy Boim, was a physician to King Sigismund III of Poland. Out of Pawel Jerzys six sons, the eldest, the neer-do-well Jerzy was disinherited, Mikołaj and Jan became merchants, Paweł, the family had their own family chapel in Lvivs central square, which was constructed around the time of Michałs birth. In 1631, Boym joined the Jesuits in Kraków, and was ordained a priest, in 1643, after almost a decade of intensive studies in the monasteries of Kraków, Kalisz, Jarosław and Sandomierz, Boym embarked on a voyage to Eastern Asia. He first traveled to Rome, where he obtained a blessing for his mission from Pope Urban VIII, later that year he embarked with a group of nine other priests and clerics on a voyage to Portuguese Goa, and then Macau. Initially he taught at St. Paul Jesuit College and he then moved to the island of Hainan, where he opened a small Catholic mission. After the island had been conquered by the Manchus, Boym had to flee to Tonkin in 1647, the Emperors eunuch secretary Pang Tianshou, known by his Christian name Achilles, had become a Christian as well, years earlier. Boym was chosen to present the situation of the Chinese Emperor to the Pope and he received letters from Empress dowager Helena and from Pang Achilles, to give to Pope Innocent X, the General of the Jesuit Order, and Cardinal John de Lugo. Additional letters were dispatched to the Doge of Venice and to the King of Portugal, together with a young court official named Andrew Zheng, Boym embarked on his return voyage to Europe. This view was supported by the new local superior of the Jesuits. Boym was placed under house arrest, however, he managed to escape and continue his voyage on foot. By way of Hyderabad, Surat, Bander Abbas and Shiraz, he arrived at Isfahan, from there he continued his journey to Erzerum, Trabzon and İzmir, where he arrived near the end of August 1652. As the Venetian court was having conflicts with the Jesuits, Boym discarded his habit and dressed up as a Chinese Mandarin, before he arrived in Venice in December of that year. Although he had managed to cross uncharted waters and unknown lands, his mission there would not be easy, initially the Doge of Venice refused to grant Boym an audience, as Venice wanted to maintain a neutral stance in regards to China. Boym managed to convince the French ambassador to support his cause, however, the French involvement caused a negative reaction from the Pope, as Innocent X was actively opposed to France and its ambitions. Also the newly elected General of the Jesuits, Gosvinus Nickel, believed Boyms mission might endanger other Jesuit missions in China, a new Pope was elected in 1655, and after three years, Alexander VII finally saw Boym on December 18,1655. However, the letter from the new Pope opened many doors for Boym, in Lisbon, he was granted an audience by King John IV, who promised to help the Chinese struggle with military force

Flora Sinensis is one of the first European natural history books about China, published in Vienna in 1656. Its author, Michael Boym, was a Jesuit missionary from Poland, the book was the first description of an ecosystem of the Far East published in Europe. Boym underlined the medicinal properties of the Chinese plants and it is said that the Flora Sinensis was the first book that used the name Flora in this meaning, a book covering the plant world of a region. However, despite its title, the book covered not only plants, it obviously includes some species that are neither plants nor Chinese

Malayalam language
–
Malayalam /mʌləˈjɑːləm/ is a language spoken in India, predominantly in the state of Kerala. It is one of the 22 scheduled languages of India and was designated as a Classical Language in India in 2013 and it was developed to the current form mainly by the influence of the poet Thunchaththu Ezhuthachan in the 16th century. Malayalam has official status in the state of Kerala and in the union territories of Lakshadweep. It belongs to the Dravidian family of languages and is spoken by some 38 million people, according to one theory, Malayalam originated from Middle Tamil in the 7th century. However, the current understanding proposes the separation of Malayalam from Proto-Dravidian in the pre-historic era, Malayalam incorporated many elements from Sanskrit through the ages. Before Malayalam came into being, Old Tamil was used in literature and courts of a region called Tamilakam, including present day Kerala state, silappatikaramit was written by Chera prince Ilango Adigal from Chunkaparra, and is considered a classic in Sangam literature. Modern Malayalam still preserves many words from the ancient Tamil vocabulary of Sangam literature, the earliest script used to write Malayalam was the Vatteluttu alphabet, and later the Kolezhuttu, which derived from it. As Malayalam began to borrow words as well as the rules of grammar from Sanskrit. This developed into the modern Malayalam script, many medieval liturgical texts were written in an admixture of Sanskrit and early Malayalam, called Manipravalam. The oldest literary work in Malayalam, distinct from the Tamil tradition, is dated from between the 9th and 11th centuries, the first travelogue in any Indian language is the Malayalam Varthamanappusthakam, written by Paremmakkal Thoma Kathanar in 1785. Due to its lineage deriving from both Tamil and Sanskrit, the Malayalam script has the largest number of letters among the Indian language orthographies, the Malayalam script includes letters capable of representing almost all the sounds of all Indo-Aryan and Dravidian languages. Malayalam serves as a language on the islands including the Mahl-dominated Minicoy Island. The word Malayalam originated from the Sanskrit resp, Malayalam words malai or mala, meaning hill, and elam, meaning region. Malayalam thus translates as hill region and used to refer to the land of the Chera dynasty, the language Malayalam is alternatively called Alealum, Malayalani, Malayali, Malean, Maliyad, and Mallealle. The word Malayalam originally meant only for the name of the region, Malayanma or Malayayma represented the language. With the emergence of modern Malayalam language, the name of the language started to be known by the name of the region, hence now, the word Malayanma is considered by some to represent the olden Malayalam language. The language got the name Malayalam during the mid 19th century, the origin of Malayalam, an independent offshoot of the proto-Dravidian language, has been and continues to be an engaging pursuit among comparative historical linguists. Together with Tamil, Toda, Kannada and Tulu, Malayalam belongs to the group of Dravidian languages

Portuguese language

Portuguese is a Romance language and the sole official language of Portugal, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Angola, and São Tomé and Príncipe. It also has co-official language status in East Timor, Equatorial Guinea, Portuguese is part of the Ibero-Romance group that evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia, and has kept some Celtic phonology. Portuguese is also termed the language of Camões, after Luís Vaz de Camões, one of the greatest literary figures in the Portuguese language and author of the Portuguese epic poem, the museum is the first of its kind in the world. In 2015 the museum was destroyed in a fire, but there are plans to reconstruct it, when the Romans arrived in the Iberian Peninsula in 216 BCE, they brought the Latin language with them, from which all Romance languages descend. Between 409 CE and 711 CE, as the Roman Empire collapsed in Western Europe, Portuguese evolved from the medieval language, known today by linguists as Galician-Portuguese, Old Portuguese or Old Galician, of the northwestern medieval Kingdom of Galicia. It is in Latin administrative documents of the 9th century that written Galician-Portuguese words and this phase is known as Proto-Portuguese, which lasted from the 9th century until the 12th-century independence of the County of Portugal from the Kingdom of León, by then reigning over Galicia. In the first part of the Galician-Portuguese period, the language was used for documents. For some time, it was the language of preference for poetry in Christian Hispania. Portugal became an independent kingdom in 1139, under King Afonso I of Portugal, in the second period of Old Portuguese, in the 15th and 16th centuries, with the Portuguese discoveries, the language was taken to many regions of Africa, Asia and the Americas. The language continued to be popular in parts of Asia until the 19th century, some Portuguese-speaking Christian communities in India, Sri Lanka, Malaysia, and Indonesia preserved their language even after they were isolated from Portugal. The end of the Old Portuguese period was marked by the publication of the Cancioneiro Geral by Garcia de Resende, Most literate Portuguese speakers were also literate in Latin, and thus they easily adopted Latin words into their writing—and eventually speech—in Portuguese. Portuguese is the language of the majority of people in Brazil and Portugal, perhaps 75% of the population of Angola speaks Portuguese natively, and 85% are fluent. Just over 40% of the population of Mozambique are native speakers of Portuguese, Portuguese is also spoken natively by 30% of the population in Guinea-Bissau, and a Portuguese-based creole is understood by all. No data is available for Cape Verde, but almost all the population is bilingual, there are also significant Portuguese speaking immigrant communities in many countries including Andorra, Bermuda, Canada, France, Japan, Jersey, Namibia, Paraguay, Macau, Switzerland, Venezuela. In some parts of former Portuguese India, namely Goa and Daman and Diu, in 2014, an estimated 1,500 students were learning Portuguese in Goa. Equatorial Guinea made an application for full membership to the CPLP in June 2010. In 2011, Portuguese became its official language and, in July 2014. Portuguese is a subject in The school curriculum in Uruguay

Ludovico di Varthema
–
Ludovico di Varthema, also known as Barthema and Vertomannus, was an Italian traveller, diarist and aristocrat known for being the first non-Muslim European to enter Mecca as a pilgrim. Nearly everything that is known about his life comes from his own account of his travels, Itinerario de Ludouico de Varthema Bolognese, published in Rome in 1510. He was perhaps a soldier before beginning his distant journeys, which he undertook apparently from a passion for adventure, novelty, Varthema left Europe near the end of 1502. Early in 1503, he reached Alexandria and ascended the Nile to Cairo, from Egypt, he sailed to Beirut and thence travelled to Tripoli, Aleppo and Damascus, where he managed to get himself enrolled, under the name of Yunas, in the Mamluk garrison. From Damascus, Varthema made the journey to Mecca and Medina as one of the Mamluk escorts of a Hajj pilgrim caravan and he describes the sacred cities of Islam and the chief pilgrim sites and ceremonies with remarkable accuracy, almost all his details being confirmed by later writers. Varthema may very well have been the first non-Muslim European to visit these cities, while in Mecca, Varthema was confronted by a Muslim overseas merchant, who accused him of being a Christian spy. When Varthema protested that he was a Mamluk, the suspicions were allayed, the merchant explained to Varthema that nerves were on edge on account of the activities of the Portuguese, who had recently begun encroaching on the Indian Ocean and attacking Muslim shipping. Hearing these stories, Varthema conceived of a ruse to get to India, Varthema presented himself as a master cannon founder, seeking to offer his services to the Muslim Sultan of Bijapur, to cast artillery to fight the Portuguese. Impressed by Varthemas resolution, the overseas Meccan merchant hid Varthema in his home, with the Meccan merchants assistance, Ludovico de Varthema embarked an Arab merchant vessel at Jeddah, a city-port around 80 km west to Mecca, destined for India. It sailed down the Red Sea and through the Straits of Bab-el-Mandeb to Aden, however, upon reaching Aden, he was arrested and imprisoned as a Christian spy. The sultana kept him in her palace at Radaa for a while, eventually, feigning a malady, Varthema secured the sultanas permission to leave Radaa to seek out a cure with a specialist in Aden. He subsequently took a tour through south-west Arabia, before returning to Aden again. Probably using the sultanas cash gift, Varthema purchased passage on an Arab ship for India, by now it was March 1504. The ship was supposed to make a stop in the Persian Gulf first, but contrary winds forced it in the opposite direction and he gives brief descriptions of both places. From Somalia, the ship proceeded to sail across the Arabian Sea to the Indian port of Diu in Gujarat, from Diu, it sailed up the Gulf of Cambay to Gogo. Business done there, the ship sailed back across the Arabian Sea to the Persian Gulf, arriving in Ormuz in the aftermath of a palace coup, Ludovico de Varthema did not linger for long, but proceeded to cross to mainland Persia. He seems to have traveled northeast across Persia to Herat, along the way, he passed a river which he identifies as the Euphrates In Shiraz, Varthema came by chance across a Persian merchant whom he had met earlier in Mecca. The Persian merchant, named Cazazioner in the chronicle, entered into a partnership with Varthema, the two would remain together for the remainder of Varthemas travels in Asia

Hendrik van Rheede
–
Hendrik Adriaan van Rheede tot Drakenstein was a military man and a colonial administrator of the Dutch East India Company and naturalist. Between 1669 and 1676 he served as a governor of Dutch Malabar and employed twenty-five people on his book Hortus Malabaricus, as Lord of Mydrecht, he also played a role in the governance of the Cape colonies. The plant Entada rheedii is named for him, Van Rheede was born into a family of noblemen that played a leading role in the political, administrative and cultural life of the province of Utrecht. His mother, Elisabeth van Utenhove, died in 1637 while his father, Ernst van Rheede, Council at the Admiralty of Amsterdam, Hendrik Adriaan, the youngest of seven children, left home at the age of fourteen. In 1656 he joined as a soldier in the Dutch East India Company, Van Rheede served under Admiral Rijcklof van Goens in campaigns against the Portuguese on the west coast of India in erstwhile Dutch Malabar. He gained rapid promotion becoming an ensign, in 1663, during a siege of Cochin, he was ordered to arrest the queen there and this act saved her life from the massacre of the royal family. The subsequent king of Cochin maintained cordial relations with him and Van Rheede was the Dutch captain who mediated with the Kingdom of Cochin, in 1665 he was appointed as commander in Jaffna and had Johan Nieuhof locked up for smuggling pearls. In 1669 Van Rheede seems to have forced to resign from the Dutch East India Company by Van Goens. The resignation was made as he opposed the measures of Van Goens and instead favoured negotiation. In 1671 he fought with the Zamorin of Calicut, in 1672 he had to deal with the former VOC-employee François Caron, then serving the French East India Company. In 1677 Van Rheede moved to Jakarta, being appointed in the Counsel of India and he stayed for about six months but the conflict with Van Goens grew fiercer. He returned to Amsterdam in June 1678, since 1680 he could call himself Lord of Mijdrecht. In 1681 he signed a contract with the botanists Jan Commelin and Johannes Munnicks, in 1684 he was empowered by the directors of the Company to inspect the Cape Colony, Ceylon and Dutch India to combat corruption within their employees. He appointed Isaac Soolmans to accompany him and they visited Simon van der Stel in Cape of Good Hope, and Groot Constantia, the area Groot Drakenstein was named after him. Van Rheede recommended measures for forestry and viniculture, Rheede, the Lord of Mydrecht, also made rules on how slaves would be treated and he decreed that slave children had to be taught to read and write with any flogging requiring permission. In 1687 Governor Van der Stel opened this region to farmers, Van Rheede was a bachelor, but had adopted a girl from Malabar with an unknown Dutch father. He met with Van Goens junior, an administrator on his way to Batavia. Both men didnt like each other at all and it is possible that the rare trees for the Grand Pensionary Gaspar Fagel were then also destroyed

Hortus Malabaricus
–
Written in Latin, it was compiled over a period of nearly 30 years and published in Amsterdam during 1678–1693. The book was conceived by Hendrik van Rheede, who was the Governor of Dutch Malabar at the time, the book has been translated into English and Malayalam by K. S. Manilal and published by the University of Kerala. The Hortus Malabaricus comprises 12 volumes of about 200 pages each, the first of the 12 volumes of the book was published in 1678, and the last in 1693. It is believed to be the earliest comprehensive printed work on the flora of Asia, mentioned in these volumes are plants of the Malabar region which in his time referred to the stretch along the Western Ghats from Goa to Kanyakumari. The book gives an account of the flora of Kerala, along with sketches. Over 742 different plants and their indigenous science are considered in the book, the book also employs a system of classification based on the traditions adopted by the practitioners of that region. Apart from Latin, the plant names have been recorded in languages including Malayalam, Konkani, Arabic. The comprehensive nature of the book is noted by T, the Secretary to Government, Herman Van Douep, further translated it into Latin, that the learned in all the countries of Europe might have access to it. The whole seems then to have passed under the supervision of another learned individual named Casearius, who was probably a Dutch Chaplain and a personal friend of Van Rheede. A book of its size, on which care was expended, must have consumed a fortune before its publication. Several species of plants have their type illustrations in this work, Hendrik van Rheede is said to have taken a keen personal interest in the compilation of the Hortus Malabaricus. The work was edited by a team of nearly a hundred including, Physicians, such as Ranga Bhat, Vinayaka Pandit, Appu Bhat, and Itti Achuden. Professors of medicine and botany Amateur botanists, such as Arnold Seyn, Theodore Jansson of Almeloveen, Paul Hermann, Johannes Munnicks, Joannes Commelinus, Van Rheede was also assisted by the King of Cochin and the ruling Zamorin of Calicut. The ethnomedical original information in the work was provided by these three working on it for two continuous years morning and evening as certified by them and their certificate to this effect is given in the first volume of the book. A grand memorial to them is erected in Kochi, professor K. S. Manilal has worked over 35 years on the research, translations, and annotations of the Hortus Malabaricus. The effort has brought the main contents of the book to Malayalam and it had largely remained inaccessible previously to them, because of the entire text being untranslated into the English language and Malayalam language

Thirteen colonies
–
The Thirteen Colonies were a group of British colonies on the east coast of North America founded in the 17th and 18th centuries that declared independence in 1776 and formed the United States. The Thirteen Colonies had very similar political, constitutional, and legal systems and they were part of Britains possessions in the New World, which also included colonies in present-day Canada and the Caribbean, as well as East and West Florida. However, the Thirteen Colonies had a degree of self-government and active local elections. In the 1750s, the colonies began collaborating with each other instead of dealing directly with Britain, Colonial decisions were subject to approval by the governor and the home government. There were also substantial populations of African slaves in some of the colonies, especially Virginia, the Carolinas, the names of the colonies were chosen by the founders and proprietors, subject to royal approval, and given in the founding charters. Nine of the thirteen chose to include in their names the term Province of, later residents tended to drop the ambiguous terminology, as in the map shown in the article Province of New Jersey, which is labeled simply East Jersey and West Jersey. In July 1776, they formed a new nation called the United States of America, the new nation achieved that goal by winning the American Revolutionary War with the aid of France, the Netherlands, and Spain. The American flag features thirteen horizontal stripes which represent these original thirteen colonies, besides these thirteen colonies, Britain had another dozen in the New World. Those in the British West Indies, Newfoundland, the Province of Quebec, Nova Scotia, Prince Edward Island, Bermuda, and East and West Florida remained loyal to the crown throughout the war. The British crown had recently acquired those lands, and many of the issues facing the Thirteen Colonies did not apply to them, especially in the case of Quebec. Contemporary documents usually list the thirteen colonies of British North America in geographical order, the consolidation collapsed after the Glorious Revolution of 1688–89, and the nine former colonies re-established their separate identities in 1689. Massachusetts Bay Colony Settled in 1630 by Puritans from England, the colonial charter was revoked in 1684, and a new charter was issued in 1691 establishing an enlarged Province of Massachusetts Bay. Province of Maine Settled in 1622, the Massachusetts Bay Colony claimed the Maine territory in the 1650s, then limited to present-day southernmost Maine. Parts of Maine east of the Kennebec River were also part of New York in the half of the 17th century. These areas were made part of the Province of Massachusetts Bay in the charter of 1691. Plymouth Colony Settled in 1620 by the Pilgrims, plymouth was merged into the Province of Massachusetts Bay in the charter of 1691. Saybrook Colony Founded in 1635 and merged with Connecticut Colony in 1644, New Haven Colony Settled in late 1637. New Netherland Extensive region centered about New Amsterdam at the tip of Manhattan Island

Pickling
–
Pickling is the process of preserving or expanding the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar. The resulting food is called a pickle, or, to prevent ambiguity, the pickling procedure will typically affect the foods texture and flavor. In East Asia, vinaigrette is used as a pickling medium. Foods that are pickled include meats, fruits, eggs, another distinguishing characteristic is a pH of 4.6 or lower, which is sufficient to kill most bacteria. Pickling can preserve perishable foods for months, antimicrobial herbs and spices, such as mustard seed, garlic, cinnamon or cloves, are often added. If the food contains sufficient moisture, a pickling brine may be produced simply by adding dry salt, for example, German sauerkraut and Korean kimchi are produced by salting the vegetables to draw out excess water. Natural fermentation at room temperature, by lactic acid bacteria, produces the required acidity, other pickles are made by placing vegetables in vinegar. Unlike the canning process, pickling does not require that the food be completely sterile before it is sealed, the acidity or salinity of the solution, the temperature of fermentation, and the exclusion of oxygen determine which microorganisms dominate, and determine the flavor of the end product. When both salt concentration and temperature are low, Leuconostoc mesenteroides dominates, producing a mix of acids, alcohol, at higher temperatures Lactobacillus plantarum dominates, which produces primarily lactic acid. Many pickles start with Leuconostoc, and change to Lactobacillus with higher acidity, pickling began 4000 years ago using cucumbers native to India. This was used as a way to food for out-of-season use and for long journeys. Salt pork and salt beef were common staples for sailors before the days of steam engines, although the process was invented to preserve foods, pickles are also made and eaten because people enjoy the resulting flavors. Pickling may also improve the value of food by introducing B vitamins produced by bacteria. The term pickle is derived from the Dutch word pekel, meaning brine, in the U. S. and Canada, and sometimes Australia and New Zealand, the word pickle alone almost always refers to a pickled cucumber, except when it is used figuratively. It may also refer to types of pickles such as pickled onion, pickled cauliflower. In the UK, pickle, as in a cheese and pickle sandwich, may refer to Ploughmans pickle. South Asia has a variety of pickles, which are mainly made from varieties of mango, lemon, lime, goongura, tamarind and Indian gooseberry. Vegetables such as brinjal, carrots, cauliflower, tomato, bitter gourd, green tamarind, ginger, garlic, onion and these fruits and vegetables are generally mixed with ingredients like salt, spices, and vegetable oils and are set to mature in a moistureless medium

Refrigeration
–
Refrigeration is a process of moving heat from one location to another in controlled conditions. The work of heat transport is driven by mechanical work. Refrigeration has many applications, including, but not limited to, household refrigerators, industrial freezers, cryogenics, heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Refrigeration has had a impact on industry, lifestyle, agriculture. The idea of preserving food dates back to at least the ancient Roman, however, mechanical refrigeration technology has rapidly evolved in the last century, from ice harvesting to temperature-controlled rail cars. Settlements were also developing in parts of the country, filled with new natural resources. These new settlement patterns sparked the building of cities which are able to thrive in areas that were otherwise thought to be inhospitable, such as Houston, Texas and Las Vegas. In most developed countries, cities are heavily dependent upon refrigeration in supermarkets, the increase in food sources has led to a larger concentration of agricultural sales coming from a smaller percentage of existing farms. Farms today have a larger output per person in comparison to the late 1800s. This has resulted in new food sources available to entire populations, the seasonal harvesting of snow and ice is an ancient practice estimated to have begun earlier than 1000 B. C. A Chinese collection of lyrics from this period known as the Shih king. However, little is known about the construction of these ice cellars or what the ice was used for. ”Historians have interpreted this to mean that the Jews used ice to cool beverages rather than to preserve food. Other ancient cultures such as the Greeks and the Romans dug large snow pits insulated with grass, chaff, like the Jews, the Greeks and Romans did not use ice and snow to preserve food, but primarily as a means to cool beverages. Slaves would moisten the outside of the jars and the resulting evaporation would cool the water, the ancient people of India used this same concept to produce ice. The Persians stored ice in a pit called a Yakhchal and may have been the first group of people to use storage to preserve food. In the Australian outback before a reliable electricity supply was available where the weather could be hot and dry and this consisted of a room with hessian curtains hanging from the ceiling soaked in water. The water would evaporate and thereby cool the hessian curtains and thereby the air circulating in the room and this would allow many perishables such as fruit, butter, and cured meats to be kept that would normally spoil in the heat. Before 1830, few Americans used ice to refrigerate foods due to a lack of ice-storehouses and iceboxes, as these two things became more widely available, individuals used axes and saws to harvest ice for their storehouses

Bell pepper
–
The bell pepper is a cultivar group of the species Capsicum annuum. Cultivars of the plant produce fruits in different colors, including red, yellow, orange, green, chocolate/brown, vanilla/white, bell peppers are sometimes grouped with less pungent pepper varieties as sweet peppers. The whitish ribs and seeds inside bell peppers may be consumed, peppers are native to Mexico, Central America, and northern South America. Pepper seeds were imported to Spain in 1493, and from there spread to other European, African, today, China is the worlds largest pepper producer, followed by Mexico and Indonesia. Ideal growing conditions for peppers include warm soil, ideally 21 to 29 °C. Bell peppers are sensitive to an abundance of moisture and extreme temperatures, the misleading name pepper was given by Europeans when Christopher Columbus brought the plant back to Europe. The most commonly used name of the plant family, chile, is of Mexican origin. Botanically speaking, bell peppers are fruit, although they are considered vegetables in culinary contexts. The lack of capsaicin in bell peppers is due to a form of a gene that eliminates capsaicin and, consequently. This recessive gene is overwritten in the Mexibelle pepper, a variety of bell pepper that produces small amounts of capsaicin. Sweet pepper cultivars produce non pungent capsaicinoids, with many physiological effects similar to the more pungent sister compound capsaican, the terms bell pepper, pepper, and capsicum are often used for any of the large bell shaped fruits, regardless of their color. In British and Canadian English, the fruit is referred to as a pepper, or additionally by color, whereas in the United States and Malaysia. In parts of the U. S. Midwest, bell peppers are called mangoes, Canadian English uses both bell pepper and pepper interchangeably. In some languages, the term paprika, which has its roots in the word for pepper, is used for both the spice and the fruit – sometimes referred to by their color, the bell pepper is called パプリカ or ピーマン in Japan. In Switzerland, the fruit is called peperone, which is the Italian name of the fruit. In France, it is called poivron, with the root as poivre or piment. In South Korea, the word 피망 refers to bell peppers. In Sri Lanka, the used as a vegetable is called maalu miris

Mandarin Chinese
–
Mandarin is a group of related varieties of Chinese spoken across most of northern and southwestern China. The group includes the Beijing dialect, the basis of Standard Mandarin or Standard Chinese, because most Mandarin dialects are found in the north, the group is sometimes referred to as the Northern dialects. Many local Mandarin varieties are not mutually intelligible, nevertheless, Mandarin is often placed first in any list of languages by number of native speakers. Most Mandarin varieties have four tones, the final stops of Middle Chinese have disappeared in most of these varieties, but some have merged them as a final glottal stop. Many Mandarin varieties, including the Beijing dialect, retain retroflex initial consonants, the capital has been within the Mandarin area for most of the last millennium, making these dialects very influential. Some form of Mandarin has served as a lingua franca since the 14th century. In the early 20th century, a form based on the Beijing dialect. Standard Chinese is the language of the Peoples Republic of China and Taiwan. Since their native varieties were often mutually unintelligible, these officials communicated using a Koiné language based on various northern varieties, when Jesuit missionaries learned this standard language in the 16th century, they called it Mandarin, from its Chinese name Guānhuà, or language of the officials. In everyday English, Mandarin refers to Standard Chinese, which is called simply Chinese. Standard Chinese is based on the particular Mandarin dialect spoken in Beijing, with some lexical and it is the official spoken language of the Peoples Republic of China, the official language of the Republic of China, and one of the four official languages of the Republic of Singapore. It also functions as the language of instruction in Mainland China and it is one of the six official languages of the United Nations, under the name Chinese. Chinese speakers refer to the standard language as Pǔtōnghuà in Mainland China, Guóyǔ in Taiwan, or Huáyǔ in Singapore, Malaysia, Indonesia and Philippines. Linguists use the term Mandarin to refer to the group of dialects spoken in northern and southwestern China. The alternative term Běifānghuà, or Northern dialects, is used less and less among Chinese linguists, by extension, the term Old Mandarin or Early Mandarin is used by linguists to refer to the northern dialects recorded in materials from the Yuan dynasty. Native speakers who are not academic linguists may not recognize that the variants they speak are classified in linguistics as members of Mandarin in a broader sense, the hundreds of modern local varieties of Chinese developed from regional variants of Old Chinese and Middle Chinese. Traditionally, seven groups of dialects have been recognized. Aside from Mandarin, the six are Wu, Gan and Xiang in central China

Pinyin
–
Pinyin, or Hànyǔ Pīnyīn, is the official romanization system for Standard Chinese in mainland China, Malaysia, Singapore, and Taiwan. It is often used to teach Standard Chinese, which is written using Chinese characters. The system includes four diacritics denoting tones, Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters. The pinyin system was developed in the 1950s by many linguists, including Zhou Youguang and it was published by the Chinese government in 1958 and revised several times. The International Organization for Standardization adopted pinyin as a standard in 1982. The system was adopted as the standard in Taiwan in 2009. The word Hànyǔ means the language of the Han people. In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji in Beijing and this was the first book to use the Roman alphabet to write the Chinese language. Twenty years later, another Jesuit in China, Nicolas Trigault, neither book had much immediate impact on the way in which Chinese thought about their writing system, and the romanizations they described were intended more for Westerners than for the Chinese. One of the earliest Chinese thinkers to relate Western alphabets to Chinese was late Ming to early Qing Dynasty scholar-official, the first late Qing reformer to propose that China adopt a system of spelling was Song Shu. A student of the great scholars Yu Yue and Zhang Taiyan, Song had been to Japan and observed the effect of the kana syllabaries. This galvanized him into activity on a number of fronts, one of the most important being reform of the script, while Song did not himself actually create a system for spelling Sinitic languages, his discussion proved fertile and led to a proliferation of schemes for phonetic scripts. The Wade–Giles system was produced by Thomas Wade in 1859, and it was popular and used in English-language publications outside China until 1979. This Sin Wenz or New Writing was much more sophisticated than earlier alphabets. In 1940, several members attended a Border Region Sin Wenz Society convention. Mao Zedong and Zhu De, head of the army, both contributed their calligraphy for the masthead of the Sin Wenz Societys new journal. Outside the CCP, other prominent supporters included Sun Yat-sens son, Sun Fo, Cai Yuanpei, the countrys most prestigious educator, Tao Xingzhi, an educational reformer. Over thirty journals soon appeared written in Sin Wenz, plus large numbers of translations, biographies, some contemporary Chinese literature, and a spectrum of textbooks
