"The species is recognized by the white to creamy white flowers, the sepals somewhat dorsally tinged with purple, sepals .44 to .56" [11 to 14 mm]long, with a prominent dorsal awn, petals elliptic, obtuse, -2 to .24" [5 to 6 mm] wide, the lateral lobes of the lip dolabriform, midlobe emarginate with a prominent mucro. Epidendrum suaveolens Ames has greenish white to creamy yellow flowers, the lateral sepals with a low, erose awn, .56 to .64" [14 to 16 mm] long, elliptic to oblong-oblanceolate petals apically rounded and minutely apiculate,.2 to .28" [5 to 7 mm] wide, the lateral lobes of the lip suborbicular, and the midlobe widely and shortly apiculate.
