The subgenus Hormidium of the genus Epidendrum of family 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.[1]

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.[2] 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):
- E. miserum Lindl. 1841 (p. 346)
- E. serpens Lindl. 1845 (p. 346)
With these species should be included the members of the "Serpens group":[3]
- E. carmelense Hágsater & Dodson 1993
- E. garayi Løjtnant 1977
- E. ilinazae Hágsater & Dodson 1999
- E. moronense Dodson & Hágsater 1989
- E. oxapampense Hágsater 1999
- E. pachacutequianum Hágsater & Collantes 2006
- E. platyphylloserpens Hágsater 2001
E. sophronitis Linden & Rchb.f. (1857) was placed in the genus Hormidium by G. Bentham and J. D. Hooker in 1883.[4]
