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] |
Echinosepala
''Echinosepala'' is a proposed genus of orchids comprising the subgenera ''Silenia'' and ''Satyria'' of the genus ''Myoxanthus''. There is little reason to resist this change, thus ''Echinosepala'' is widely accepted. The genus contains 8 species. The genus was formerly known as ''Echinella'' Pridgeon & M.W.Chase, but as this latter also refers to an algae genus, it has been changed to ''Echinosepala''.

Flora Of Panama
Panama is a country located in Central America, bordering both the Caribbean Sea and the Pacific Ocean, between Colombia and Costa Rica. Panama is located on the narrow and low Isthmus of Panama. This S-shaped isthmus is situated between 7° and 10° north latitude and 77° and 83° west longitude. Panama encompasses approximately . It is long, and between wide. Geology The geology of Panama is extremely complicated. The land was formed by interactions of several tectonic plates over the past 10 million years. Elevation The dominant feature of Panama's landform is the central spine of mountains and hills that forms the continental divide. The divide does not form part of the great mountain chains of North America, and only near the Colombian border are there highlands related to the Andean system of South America. The spine that forms the divide is the highly eroded arch of an uplift from the sea bottom, in which peaks were formed by volcanic intrusions. The western p ...
