Found in Colombia, Ecuador and Peru at elevations of 2400 to 2800 meters as a medium sized, cold growing epiphyte with arching to pendent stems carrying aggregate towards the apex, ovate-elliptic, acute leaves that blooms on a terminal, short, few flowered inflorescence.

"Epidendrum cornutum Lindl. is part of GROUP Alpicolum SUBGROUP Alpicolum Characterized by the simple, cane-like stems, long, narrow 1 to 3 spathaceous bracts, fox-tail-like inflorescence and numerous flowers with fleshy lip. The species is larger and proportionately narrower overall that the following comparative species, the lateral sepals are .36 to .42" [9 to 10.5 mm] long, and the midlobe of the lip nearly .16" [4 mm] long. Many other species in this group have the margin of the lateral lobes of the lip erose with the forward corner fimbriate. Epidendrum aenigmaticum is recognized by the small flowers, ochre-orange colored inside, the lateral sepals .72 to .3" [6.8 to 7.5 mm] long, the transversely ovate-elliptic lateral lobes of the lip are upright, with the margin entire, and the midlobe is short and wide. They are similar to E tenquendamae F.Lehm. & Kraenzl. which has narrower linear-lanceolate leaves, the flowers somewhat larger and proportionately narrower, sepals .28 to .32" [7 to 8 mm] long, linear-lanceolate, .24" [6 mm] long petals, and the callus of the lip somewhal shorter."
