List Of Orchidaceae Genera
This is a list of genera in the orchid family (Orchidaceae), originally according tThe Families of Flowering Plants- L. Watson and M. J. Dallwitz. This list is adapted regularly with the changes published in the ''Orchid Research Newsletter'' which is published twice a year by the Royal Botanic Gardens, Kew. The most up to date list of accepted; genera, natural nothogenera, species and natural nothospecies with their synonyms can be found on the World Checklist of Selected Plants FamilieSearch Pagepublished by the Royal Botanic Gardens, Kew. This list is reflected on Wikispecies Species:Orchidaceae, Orchidaceae and the new eMonocot websitOrchidaceae Juss. This Taxonomy (biology), taxonomy undergoes constant change, mainly through evidence from DNA study. Orchids were traditionally defined by morphological similarity (structure of their flowers and other parts). However, recent changes to nomenclature have been driven primarily by DNA studies and also by re-examination of herbarium ...

Eulophiinae Genera
Eulophiinae is an orchid subtribe in the tribe Cymbidieae. It comprises 270 species divided into nine genera, with the genus ''Eulophia'' comprising 60% of these species.

Sarah Drake
Sarah Anne Drake (1803–1857) was an English botanical illustrator who worked for John Lindley and collaborated with Augusta Innes Withers, Nathaniel Wallich and others. Biography Sarah Anne Drake was born in Skeyton, England on 24 July 1803, the same area of Norfolk as the London University botanist John Lindley and went to school with Lindley's sister Anne. John Lindley had a particular interest in the illustration of orchids and would eventually invite Sarah Drake to become an illustrator with him and study a variety of plants. As a young woman, she went to Paris, where she probably studied painting as was expected of young women of the day. In 1830 "Ducky" (as she became known) moved into the Lindley home at Acton Green in London. She appears to have had a number of roles in the Lindley home, including that of governess, but eventually took up botanical art, gradually taking over from Lindley the illustration of his botanical publications. She created illustrations for his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thouars
Thouars () is a commune in the Deux-Sèvres department in western France. On 1 January 2019, the former communes Mauzé-Thouarsais, Missé and Sainte-Radegonde were merged into Thouars. It is on the River Thouet. Its inhabitants are known as ''Thouarsais''. The Toarcian stage of the Jurassic takes its name from the town. History Although there is evidence of human habitation here 5,000 years ago, it is only in the seventh century that the town appears in the historical record. In the 760s, Thouars found itself in Aquitaine, the most robust fortress in the entire region according to contemporary chroniclers. This was a violent decade as Duke Waïfre, struggling to preserve the independence of Aquitaine, fought against the expansionist ambitions of the French King, Pepin the Short. In 762, accompanied by his son, the future Charlemagne, appeared outside Thouars. He destroyed the Gallo-Roman town and torched the castle. In the ninth century the first of a line of viscou ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchidaceae
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
