Louis-Marie Aubert Du Petit-Thouars
Louis-Marie Aubert du Petit-Thouars (5 November 1758, Bournois – 12 May 1831, Paris) was an eminent French botanist known for his work collecting and describing orchids from the three islands of Madagascar, Mauritius and Réunion. Introduction Petit-Thouars came from an aristocratic family of the region of Anjou, where he grew up in the castle of Boumois, near Saumur. In 1792, after an imprisonment of two years during the French Revolution, he was exiled to Madagascar and the nearby islands such as La Réunion (then called Bourbon). He started collecting many plant specimens on Madagascar, Mauritius and La Réunion. Ten years later he was able to return to France with a collection of about 2000 plants. Most of his collection went to the ''Muséum de Paris'', while some species ended up at Kew. He was elected member of the prestigious ''Académie des Sciences'' on 10 April 1820. Du Petit-Thouars is remembered as the author of the book ''Histoire des végétaux recueill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Endemism
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] |
