Doona Gardneri
''Doona gardneri'' is a species of flowering plant in the family Dipterocarpaceae. It is a tree Endemism, endemic to Sri Lanka. It is commonly known as red doon in English and ''rath dun'' (රත් දුන්) in Sinhalese language, Sinhalese. It is a large tree native to Sri Lanka montane rain forests, lower montane rain forest, where it prefers deep, well-drained soils.Gunatilleke, C. V. S., I. A. U. N. Gunatilleke, Ashton, P. M.

George Henry Kendrick Thwaites
George Henry Kendrick Thwaites (9 July 1812, Bristol – 11 September 1882, Kandy) was an English botanist and entomologist. Career Thwaites was initially an accountant and studied botany during his spare time. He was interested particularly in the lower plants such as the algae and the cryptogams. He became a recognised botanist when he showed that the diatoms are not animals, but algae. In 1846 he was lecturer on botany at the Bristol school of pharmacy and afterwards at the medical school. In March 1849, on the death of George Gardner, Thwaites was appointed superintendent of the botanical gardens at Peradeniya, Ceylon. A position he held for thirty years, until he resigned in 1879. He was made a Fellow of the Royal Society on 1 June 1865 following the publication of his ''Enumeratio Plantarum Zeylaniæ'', – (five fasciculi 1859–64). His notes form the most valuable portion of Frederic Moore's ''Lepidoptera of Ceylon'' (3 vols 1880–1889). He established the Cinc ...

Taxa Named By George Henry Kendrick Thwaites
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1958
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Endemic Flora Of Sri Lanka
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Adam's Peak
Adam's Peak is a conical sacred mountain located in central Sri Lanka.Capper, Daniel (2022), ''Roaming Free Like a Deer: Buddhism and the Natural World,'' Cornell University Press. It is well known for the ''Sri Pada'' (; ), a rock formation near the summit whose name is also used for the mountain itself. In Buddhist tradition the print is held to be the footprint of the Buddha, in Sri Lankan Hindu tradition that of Hanuman or Shiva (its Tamil name, , ''Sivanolipaathamalai'', means 'Mountain of Shiva's Light'), and in some Islamic and Christian traditions that of Adam or St Thomas the Apostle. The mountain is also known as Mount Malaya in Buddhist sources, particularly the Mahayana ''Lankavatara Sutra'', which states that the Buddha preached this ''sutra'' on top of the mountain. According to this ''sutra'', the mountain was the abode of Ravana, overlord of the Rakshasas and ruler of Lanka. Other names in Sanskrit sources include Mount Lanka, Ratnagiri ("Mountain of Gems ...

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either accid ...

Peter Shaw Ashton
Peter Shaw Ashton (born 27 June 1934) is a British botanist. He is Charles Bullard Professor of Forestry at Harvard University, and director of the Arnold Arboretum there from 1978 to 1987. Born in Boscombe, Bournemouth, England, Ashton received his B.A. in Biology (1956), M.A. in Biology (1960) and Ph.D. Botany (1962) from the University of Cambridge. He has worked for many years on research projects to promote the conservation and sustainable use of tropical forests, and was instrumental in the project by the Center for Tropical Forest Science to formulate a network of Forest Dynamic Plots which are surveyed regularly to sample the health of the forest; he won the Japan Prize for this in 2007. In 1983, Ashton was elected a Fellow of the American Academy of Arts and Sciences The American Academy of Arts and Sciences (The Academy) is one of the oldest learned societies in the United States.
