Epidendrum trilobochilum Hágsater & Dodson has a very similar shaped lip but shorter stems, smaller flowers, sepals ,52 to .64" [13 to 16 mm] long, and the mid-lobe of the lip wider than long. Epidendrum fruticetorum Schltr. has sepals .6 [15 mm] long, and the lip 3- lobed, with the mid-lobe oblong, acuminate, .24 x .148" [6 x 3.75 mm]. Epidendrum klotzscheanum Rchb.f. has more numerous leaves, up to 12, an arching, densely many-flowered inflorescence, the lip clearly 3- lobed, the lateral lobes obovate, mid-lobe rectangular, about twice as long as wide" Hagsater etal 2001
