'''Orchidaceae''', also called the '''Orchid family''', is the largest family of the flowering plants (Angiospermae). <ref> [http://hypertextbook.com/facts/2003/BiancaNicoletti.shtml Number of orchids] </ref> <ref> [http://www.kew.org/scihort/orchids/whystudy.html Orchid Fact File, Royal Botanic gardens, Kew] </ref> This family is comprised of about 1,000 genera and more than 15,000 species. They are botanically considered herbs, since they do not produce wood.

The greatest diversity of orchid species occurs in tropical areas, notably in mountainous areas, due to the effect of reproductive isolation of plant species caused by the mountains. Islands generally provide favorable conditions for speciation but unless they are large enough to have a variety of climates, they tend to have just a few endemic species. Such unusually large islands include Borneo, New Guinea, and Madagascar, all of which exhibit a wealth of different species, many unique to their respective island. Due to these factors, the main areas noted for having a large number of orchid species include the islands of Southeast Asia, the mountainous areas of Ecuador and Colombia and the Atlantic Jungle along the Brazilian coastal mountains, where more than fifteen hundred species have been cataloged.<ref Name="Pabst"><span style="font-variant:small-caps">Pabst G, Dungs F</span> (1975) ''Orchidaceae Brasilienses'' vol. 1, Brucke-Verlag Kurt Schmersow, Hildesheim.
