''Coilostylis'' is a genus of orchids. It was split off from the "supergenus" ''
Epidendrum'' in 2004 although the Kew currently does not recognize this genus. This genus features pseudobulbs, large bracts around the flowers, and flowers that are typically
resupinate
Resupination is derived from the Latin word ''resupinus'', meaning "bent back
with the face upward" or "on the back". "Resupination" is the noun form of the adjective "resupine" which means "being upside-down, supine or facing upward".

keikes.

) Withner & P.A.Harding, formerly ''E. viviparum'', has fusiform pseudobulbs bearing two leaves, membranacious bracts as long as the ovary, and unfringed lateral lobes of the lip. This species was named for its habit of producing many keikeis. A photo of a plant, with a flowering keikei, can be found at

Acceptance
Although the existence of the taxon ''Coilostylis'' is hard to deny, there remains some debate about its rank: is this a genus, subgenus, section, or subsection? A brief summary of recent thought (since the publication of ''The Debatable Epidendrums'') is provided.
In January, 2005, The Royal Botanic Gardens, Kew, published ''Orchid Research Newsletter'' Number 45, announcing that Volume 4 of ''Genera Orchidacearum'' was being sent to the printers. This ''Newsletter'' listed the new assignment of species to ''Coilostylis''. (This reference can be found at

As recently as December 2007, The RHS Orchid Hybrid Registration Authority was still calling ''Coilostylis vivipara'' by the name "''Epidendrum viviparum'' Lindl.
