Gastrodia Zeylanica
''Gastrodia zeylanica'' is a species of potato orchids which is endemic to Sri Lanka. It was added to the ''2007 Red list of Threatened Fauna and Flora of Sri Lanka'' as ' critically endangered', on the basis of it having only been collected from a few localities. Taxonomy It was first reported from Sri Lanka in 1864 by George Henry Kendrick Thwaites, who classified it as '' Gastrodia javanica'', this was followed by subsequent authors until 1906, when Rudolf Schlechter described the Sri Lankan specimens as a new species which he called ''G. zeylanica''. In 2019 it was synonymized as ''Demorchis zeylanica'' (''Demorchis'' is a synonym of ''Gastrodia''), by Mark Alwin Clements and David Lloyd Jones. Distribution It is native to southwest Sri Lanka. In the 1981 ''A Revised handbook to the flora of Ceylon'', Jayaweera mistakenly included illustrations of a ''Didymoplexis ''Didymoplexis'', commonly known as crystal orchids or as 双唇兰属 (shuang chun lan shu), is a g ...

Rudolf Schlechter
Friedrich Richard Rudolf Schlechter (16 October 1872 – 16 November 1925) was a German taxonomist, botanist, and author of several works on orchids. He went on botanical expeditions in Africa, Indonesia, New Guinea, South and Central America and Australia. His vast herbarium was destroyed during the bombing of Berlin in 1945. Early life Rudolf Schlechter was born on 16 October 1872 in Berlin, the third of six children. His father Hugo Schlechter was a lithographer. After finishing school at the Friedrich Wilhelm Gymnasium he started a horticulture education, first at the gardening market of Mrs. Bluth and then at the University of Berlin garden.

David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Gastrodia
''Gastrodia'', commonly known as potato orchids or as 天麻属 (tian ma shu), is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to Asia (China, the Russian Far East, Japan, Korea, Southeast Asia, the Indian Subcontinent), Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans. Description Orchids in the genus ''Gastrodia'' are leafless, terrestrial, mycotrophic herbs with a fleshy, underground rhizome and an upright flowering stem with a few to many brownish, resupinate flowers. The sepals and petals are fused to form a bell-shaped or irregular tube with the tips free. The petals are usually much smaller than the sepals and the labellum has three lobes and is fully enclosed in the tube. Taxonomy The genus ''Gastrodia'' was first formally ...

Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Henry Kendrick Thwaites
George Henry Kendrick Thwaites (9 July 1812, Bristol – 11 September 1882, Kandy) was an English botanist and entomologist. 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 Cinchona nurserie ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...
