"Epidendrum sarcostalix belongs to the GROUP Andean SUBGROUP Cernuum, characterized by the monopodial habit, cane-like stems with subapical branches which are considerably shorter than the main stem, coriaceous to sub-coriaceous leaves, and fleshy flowers, the lip entire or 3-lobed. The species is recognized by the ovate-elliptic leaves 1.4" to 2.2" x .8 to 1! [3.5 to 5 x 2 to 2.5 cm], large flowers, sepals .6 to .68" [15 to 17 mm] long, convex, widely ovate-cordiform lip with minute calli. Epidendrum sumapacense Hágsater & E. Santiago is vegetatively very similar, but the lip is sub-reniform, with small lobes, very prominent calli and 3, low keels on the disc. Epidendrum orgyale Lindl. has oblong leaves 1.12" to 2" x .4 to .48" [2.8 to 5 x 1-1.2 cm], non-resupinate flowers with a elongate ovary, sepals .48 to .56" [12 to 14 mm] long, and the lip widely cordiform and the margin serrulate."
