The species is recognized by the slightly falcate, 3-veined petals, the 3-lobed lip, the mid-lobe transversely rectangular with a very wide apical sinus, minutely apiculate, bilobed, the lobes rounded, column arched in the middle. Epidendrum oreonastes Rchb.f. 1878 has straight, linear-oblanceolate, single veined petals; the mid-lobe of the lip is entire and apically truncate, column straight. Epidendrum exaltatum Kraenzl. has shorter inflorescences, smaller flowers with sepals .4" [10 mm] long, straight, 3-veined petals, and the mid-lobe of the lip is rectangular, truncate and minutely apiculate."
