"Epidendrum thermophilum GROUP Secundum SUBGROUP Secundum Characterized as a subgroup by the bicallose lip with a central, narrow, long, wavy keel, the column is apically high and the anther is generally decumbent. The species is characterized by the very stout, tall plants with firm, coriaceous, purple marked leaves, and reddish-purple, non-resupinate flowers with three-lobed, fimbriate lip with two yellow calli and a laminar keel running down the middle. The only other species with this combination of features is Epidendrum flexuosum G.

All the other species with non-resupinate flowers in the GROUP Secundum SUBGROUP Secundum have a complex, tubercu­late callus." Hagsater etal 1993
