Kingdom Plantae Family Orchidaceae Tribe Epidendreae | Order Asparagales Subfamily Epidendroideae Subtribe Laeliinae | |
The subgenus Epidendrum subgenus Hormidium of the genus Epidendrum of the Orchidaceae features short pseudobulbs, a creeping growth habit, a very short peduncle, and a lip adnate to the column to its apex. The subgenus was published by Lindley in 1841.
In his 1861 treatise on the Orchidaceae, H. G. Reichenbach included only the five species mentioned by Lindley, after stating that the taxon was a synonym for Epidendrum Aulizeum. Three of Lindley's species are now recognized as synonyms for Prosthechea pygmaea, leaving only two species in Epidendrum subgenus Hormidium (page numbers refer to H. G. Reichenbach 1861):
With these species should be included the members of the "Serpens group":
E. sophronitis Linden & Rchb.f. (1857) was placed in the genus Hormidium by G. Bentham and J. D. Hooker in 1883.
