Hildegardia Populifolia
''Hildegardia populifolia'' is a species of flowering plant in the family Malvaceae. It is found only in the Eastern Ghats of Andhra Pradesh and Tamil Nadu in India. It is threatened by habitat loss; just about 20 trees are known to exist on the eastern slopes of the Kalrayan Hills. This is a deciduous tree growing up to 20 meters tall. It has lobed leaves and panicles of flowers with red sepals and no petals. Most trees produce both male and bisexual flowers.Raju, A. J. S., Chandra, P. H., & Krishna, J. R.

William Roxburgh
William Roxburgh FRSE FRCPE Linnean Society of London, FLS (3/29 June 1751 – 18 February 1815) was a Scottish people, Scottish surgeon and botanist who worked extensively in India, describing species and working on economic botany. He is known as the founding father of Indian botany. He published numerous works on Indian botany, illustrated by careful drawings made by Indian artists and accompanied by taxonomic descriptions of many plant species. Apart from the numerous species that he named, many species were named in his honour by his collaborators. Early life He was born on 3 June 1751 on the Underwood estate near Craigie, South Ayrshire, Craigie in Ayrshire and christened on 29 June 1751 at the nearby church at Symington, South Ayrshire, Symington. His father may have worked in the Underwood estate or he may have been the illegitimate son of a well-connected family. His early education was at Underwood parish school perhaps also with some time at Symington parish school, a ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Endemic Flora Of India (region)
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...

Sterculioideae
Sterculioideae is a subfamily of the family Malvaceae containing evergreen and deciduous trees and shrubs. A 2006 molecular study indicated the Sterculioideae was most likely to be a monophyletic group, and that it had four major clades within it. However, the relationships between the clades were not resolved. The clades consist of a: *''Cola'' clade, with the genera ''Cola'' and ''Octolobus'' of Africa and ''Pterygota'' of Africa, South America and southeast Asia forming a subclade, '' Hildegardia'' and ''Firmiana'' forming a second and ''Scaphium'' and ''Pterocymbium'' a third. *''Heritiera'' clade comprising the genus ''Heritiera'' *''Sterculia'' clade comprising the large genus ''Sterculia'' of Africa and Asia. *''Brachychiton'' clade of Australasian and New Caledonian species, including '' Brachychiton'', ''Acropogon'', ''Argyrodendron'' and ''Franciscodendron ''Franciscodendron'' is a monotypic genus in the subfamily Sterculioideae (previously the family Sterculiac ...

Stork-billed Kingfisher
The stork-billed kingfisher (''Pelargopsis capensis''), is a tree kingfisher which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast Asia, from India to Indonesia. This kingfisher is resident throughout its range. It is a very large kingfisher, measuring in length. The adult has a green back, blue wings and tail, and olive-brown head. Its underparts and neck are buff. The very large bill and legs are bright red. The flight of the stork-billed kingfisher is laboured and flapping, but direct. Sexes are similar. There are 13 races or subspecies, differing mostly in plumage detail, but ''P. c. gigantea'' of the Sulu Archipelago in the Philippines has a white head, neck and underparts. The call of this noisy kingfisher is a low and far reaching ''peer-por-por'' repeated about every 5 seconds, as well cackling ''ke-ke-ke-ke-ke-ke''. The stork-billed kingfisher lives in a variety of well-wooded habitats near lakes, rivers, or coasts. It perches quiet ...

Blue-tailed Bee-eater
The blue-tailed bee-eater (''Merops philippinus'') is a near passerine bird in the bee-eater family Meropidae. It is widely distributed across South and Southeast Asia where many populations are strongly migratory, and seen seasonally in many parts but breeding colonially in small areas across their range, mostly in river valleys, where they nest by tunneling into loamy sand banks. They are seen mostly in open habitats close to water. Description This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green; its face has a narrow blue patch with a black eye stripe, and a yellow and brown throat; the tail is blue and the beak is black. The three outer toes are united around their bases. It can reach a length of 23–26 cm, including the two elongated central tail feathers which can be just two inches more than the remaining ten feathers. Sexes are alike. This species is usually found near water and like other bee-eaters it predominantly ...

Long-tailed Shrike
The long-tailed shrike or rufous-backed shrike (''Lanius schach'') is a member of the bird family Laniidae, the shrikes. They are found widely distributed across Asia and there are variations in plumage across the range. The species ranges across much of Asia, both on the mainland and the eastern archipelagos. The eastern or Himalayan subspecies, ''L. s. tricolor'', is sometimes called the black-headed shrike. Although there are considerable differences in plumage among the subspecies, they all have a long and narrow black tail, have a black mask and forehead, rufous rump and flanks and a small white patch on the shoulder. It is considered to form a superspecies with the grey-backed shrike (''Lanius tephronotus'') which breeds on the Tibetan Plateau. Taxonomy The long-tailed shrike was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Lanius schach''. Linnaeus cited the description that ...

Red-vented Bulbul
The red-vented bulbul (''Pycnonotus cafer'') is a member of the bulbul family of passerines. It is a resident breeder across the Indian subcontinent, including Sri Lanka extending east to Burma and parts of Bhutan and Nepal. It has been introduced in many other parts of the world and has established itself in New Zealand, Argentina, Tonga and Fiji, as well as parts of Samoa, Australia, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species. Taxonomy and systematics In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-vented bulbul in his ''Ornithologie'' based on a specimen that he mistakenly believed had been collected from the Cape of Good Hope in South Africa. He used the French name ''Le merle hupé du Cap de Bonne Espérance'' and the Latin ''Merula Cristata Capitis Bonae Spei''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a spec ...

Trigona Iridipennis
The Indian stingless bee or dammar bee, ''Tetragonula iridipennis'', is a species of bee belonging to the family Apidae, subfamily Apinae. It was first described by Frederick Smith in 1854 who found the species in what is now the island of Sri Lanka. Many older references erroneously placed this species in '' Melipona'', an unrelated genus from the New World, and until recently it was placed in '' Trigona'', therefore still often mistakenly referred to as ''Trigona iridipennis''. For centuries, colonies of ''T. iridipennis'' have been kept in objects such as clay pots so that their highly prized medicinal honey can be utilized. Taxonomy and phylogenetics ''Tetragonula iridipennis'' belongs to the complex genus of stingless bees ''Tetragonula'' which contains more than 30 described species from the Indian subcontinent. Until recently, all species in the group were treated as belonging to the single genus "''Trigona''". ''Tetragonula iridipennis'' belongs to the smaller ''Iridipe ...

Kalrayan Hills
The Kalvarayan Hills are a major range of hills situated in the Eastern Ghats of the southern Indian state of Tamil Nadu. Along with the Pachaimalai, Alavaimalai, Javadi, and Shevaroy hills, they separate the Kaveri River basin to the south from the Palar River basin to the north. The hills range in height from 2000 feet to 3000 feet and extend over an area of 1095 square kilometres. The hills straddle a number of Tamil Nadu districts, extending northeast from the Salem District. The range serves as a boundary between the Salem and Kallakurichi districts. The Kalrayans are divided into two sections — the northern section, referred to as the Chinna ("little") Kalrayans, and the southern section, called the Periya ("big") Kalrayans. The Chinna Kalrayans average 2700 feet in height, while the Periya Kalrayans average 4000 feet. The range as a whole is fairly smooth, with soil well-suited for plant growth. Scrub and bushes jungles reach up to 400 metres in altitude, whil ...

Heinrich Wilhelm Schott
Heinrich Wilhelm Schott (7 January 1794 in Brünn (Brno), Moravia – 5 March 1865 at Schönbrunn Palace, Vienna) was an Austrian botanist well known for his extensive work on aroids (Araceae). He studied botany, agriculture and chemistry at the University of Vienna, where he was a pupil of Joseph Franz von Jacquin (1766–1839). He was a participant in the Austrian Brazil Expedition from 1817 to 1821. In 1828 he was appointed ''Hofgärtner'' (royal gardener) in Vienna, later serving as director of the Imperial Gardens at Schönbrunn Palace (1845). In 1852 he was in charge of transforming part of palace gardens in the fashion of an English garden. He also enriched the Viennese court gardens with his collections from Brazil. He was also interested in Alpine flora, and was responsible for development of the alpinum at Schloss Belvedere in Vienna. In 2008, botanists P.C.Boyce & S.Y.Wong published '' Schottarum'', a genus of flowering plants from Borneo belonging to the family Ar ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
