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 of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acianthera
''Acianthera'' is a genus of orchids native to the tropical parts of the Western Hemisphere, especially Brazil.de Melo, M. C., Borba, E. L., & Paiva, E. A. S. (2010)Morphological and histological characterization of the osmophores and nectaries of four species of ''Acianthera'' (Orchidaceae: Pleurothallidinae).''Plant Systematics and Evolution'' 286(3-4), 141-51. It was first described in 1842 but was not widely recognized until recently. Most of the species were formerly placed under ''Pleurothallis'' subgenus ''Acianthera''. This splitting is a result of recent DNA sequencing.
