Orchid
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 of the ... [...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 ...

Aa (plant)
''Aa'' is a genus of plants of the family Orchidaceae. Species in this genus can be found growing terrestrially in cold habitats near the snowline in the Andes and also in Costa Rica; they are usually found close to small streams. The elongated inflorescence grows from a basal rosette of leaves, terminating in a small white non-resupinate flower. This lip is fringed and hood-shaped. The flower gives off a pungent smell that attracts flies. This genus has often been included in the orchid genus '' Altensteinia''. The first scientific description of a species of this genus was made in 1815 by Karl Sigismund Kunth, naming it first ''Ophrys paleacea'' Kunth (1806)., and later ''Altensteinia paleacea''. In 1854 Heinrich Gustav Reichenbach separated ''Aa'' from ''Altensteinia'', to include two species ''Aa argyrolepis'' and ''Aa paleacea''. The genus name apparently was rendered by the author to always appear first in alphabetical listings. Another - disputed - explanation, is that H ...

Plants Described In 1920
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Flora Of Colombia
The Flora of Colombia is characterized by over 28,000 species of green plants. National Flower of Colombia The national flower of Colombia is the orchid ''Cattleya trianae'' which was named after the Colombian naturalist José Jerónimo Triana. The orchid was selected by botanist Emilio Robledo, in representation of the Colombian Academy of History to determine the most representative flowering plant of Colombia. He described it as one of the most beautiful flowers in the world and selected ''Cattleya trianae'' as National symbol. National Tree of Colombia The national tree of Colombia is the palm ''Ceroxylon quindiuense'' (Quindío wax palm) which was named after the Colombian Department of Quindío where is located the Cocora valley, the only habitat of this restricted range species. The Quindío wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as a protected species in Colombia. ''C.quindiuens ...
