"Epidendrum orbiculatum belongs to the Cupreum Subgroup of the GROUP Megalospathum SUBGROUP Cupreum, recognized by the wide, single, semiovate spathe, the erect stems with 3 to 5 coriaceous leaves, and resupinate flowers; the ventral surface of the column with a cavity accessed through a long narrow slit. The species has a sub-orbicular lip, somewhat wider than long, the margin entire. The two following species have been generally confused with it. Epidendrum kymatochilum Hágsater & Dodson from the border between Ecuador and Peru is recognized by the cuneate, flabellate, lip, with a pair of incipient, basal hemi-circular lobes, their margin undulate. Epidendrum cupreum F.C.Lehm. & Kraenzl. has smaller flowers, the sepals .4" [10 mm] long, and the lip ecallose; this species is distributed along the eastern slope of the Andes from southern Colombia to southern Ecuador."
