Takhtajania Perrieri
''Takhtajania'' is a genus of flowering plants of the family Winteraceae, which contains a single species, ''Takhtajania perrieri''. It is endemic to Madagascar. ''Takhtajania'' is found in a small area of the Madagascar subhumid forests. It is a small evergreen tree or shrub, with shiny green lance-shaped leaves and reddish-pink flowers. The first known specimen of the plant was collected in 1909 on the Manongarivo Massif of central Madagascar at an elevation of 1700 meters. In 1963, the French botanist René Paul Raymond Capuron examined the unidentified plant sample, which he identified as a new species, which he named ''Bubbia perrieri'', after the French botanist Henri Perrier de la Bâthie, classifying it in the Australasian Winteraceae genus '' Bubbia''. In 1978, the botanists Baranova and J. F. Leroy reclassified the plant into its own genus, ''Takhtajania'', after the Russia Russia (, , ), or the Russian Federation, is a transcontinental country spanning Ea ...

Jean-François Leroy (botanist)
Jean-François Leroy (; 24 September 1729 - 1791) was a French architect. For the Prince of Condé, he worked on the Château of Chantilly, the Palais Bourbon, and the Hôtel de Lassay, where he replaced in 1780. Biography Leroy was born in Chantilly, the son of Jean-Jacques Leroy, building inspector of the Prince of Condé, and Mary-Anne Dunu, daughter of the superintendent of the Château de Chantilly. He entered the service of the prince, following his father. In 1761, he married Toudouze Françoise-Thérèse, daughter of the prince's master of the hunt. He was appointed architect of the Château de Chantilly in 1768, upon the death of his predecessor, Brice Le Chauve. In Chantilly, he built the Château d'Enghien (1769–1770) and the Hameau de Chantilly (1774–1775). He worked with Claude Billard de Bélisard on the Palais Bourbon and the Hôtel de Lassay, and then succeeded him in about 1780. In 1782 he revised Bélisard's plan for the Place du Palais Bourbon.

René Paul Raymond Capuron
René Paul Raymond Capuron (20 October 1921 – 24 August 1971) was a French botanist. Capuron was responsible for an extensive amount of work on the tree flora of Madagascar. Several tree taxa with the specific epithet of ''capuronii'' honor his name, examples being '' Podocarpus capuronii'' and '' Schizolaena capuronii''. Works Highlights of his work include: *''M. arillata'' — a new species of ''Mauloutchia'', formed from the collection of ''Myristicaceae'' specimens. *''Takhtajania perrieri'' — the only extant representative of the family '' Winteraceae''. Capuron was the first to rediscover the plant, following its last sighting by Henri Perrier de la Bathie, back in 1909.

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Madagascar
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] |
Canellales Genera
Canellales is the botanical name for an order of flowering plants, one of the four orders of the magnoliids. It is recognized by the most recent classification of flowering plants, the APG IV system. It is defined to contain two families: Canellaceae and Winteraceae, which comprise 136 species of fragrant trees and shrubs. The Canellaceae are found in tropical America and Africa, and the Winteraceae are part of the Antarctic flora (found in diverse parts of the southern hemisphere). Although the order was defined based on phylogenetic studies, a number of possible synapomorphies have been suggested, relating to the pollen tube, the seeds, the thickness of the integument, and other aspects of the morphology. Until 1999, these two families were not considered to be closely related. Instead the Winteraceae were considered to be a primitive family (due to the structure of the xylem and carpel, a structure which now seems to be derived from xylem and carpels more typical of the a ...

Monotypic Magnoliid Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Australasian Realm
The Australasian realm is a biogeographic realm that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccan islands (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas. The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian r ...
