The species can be recognized by its laterally compressed stems, larger leaves, inflated ovary, suborbicular lobes of the midlobe of the lip, non-keeled lip, subglobose calli, prominent, tripartite clinandrium, the central part bifid, papillose column and ovary. It is similar to E. carnevalii, a species endemic to Venezuela, in the central and western section of the Coastal Range, but that has somewhat laterally compressed stems, short leaves, divergent, prominent calli, entire clinandrium. Epidendrum chlorocorymbos Schltr., from the Atlantic Slopes from Mexico to Panama has larger plants and flowers, terete stems, more than 10 flowers, short clinandrium and glabrous column and ovary. Epidendrum littorale Hágsater & Dodson from Ecuador and Colombia, in the coastal plain at the base of the western andean ridge, has terete stems, broad, prominent, crenate midlobe of the lip, with a wide, shallow apical sinus, entire clinandrium and glabrous column and ovary. Epidendrum romanii Hágsater & Dodson, endemic to Ecuador, has terete stems, ascending leaves, entire, obconical clinandrium and glabrous column and ovary." Hagsater etal 2001
