" Epidendrum mormontoyi belongs to the GROUP Andean SUBGROUP Renilabium which is characterized by the tall plants, monopodial habit, generally large, bilobed leaves, racemose inflorescence, entire or 3-lobed lip with a channel at the base of the disc between the calli; but differs in having non-branching stems with a sympodial habit, and acute leaves. The species is recognized by the simple, cane-like stems, arching nutant racemose inflorescence, deeply 3-lobed lip, pale green flowers, suffused with brown around the laminar calli; bicallose, the calli somewhat sigmoid, conspicuously laminar, with a channel at the base of the disc between the calli, turning into a wide, low, fleshy rib, conspicuously liguliform, that runs the length of the lip and ends in a wide mucro in the apical sinus; lateral lobes transversely and asymmetrically pentagonal, external margin minutely papillose; mid-lobe transversely quadrate, apex somewhat bilobed, the lobes rounded. Epidendrum inamoenum Kraenzl. is very similar, though the plants are monopodial and branching, flowers are similarly colored and shaped, but smaller, the sepals are .36 to .4" [9 to 10 mm] long, petals .28 to .32 x .12 to .16" [7 to 8 x 3 to 4 mm], and column .24" [6 mm] long, the lip is proportionately broader than long, and the floral segments apically obtuse. Epidendrum x renipichinchae Hágsater & E.Santiago also has a 3-lobed lip, somewhat larger flowers, sepals .64 to .72" [16 to 18 mm] long, and creamy-yellow, the lateral lobes of the lip are dolabriform, margin minutely erose."
