"Epidendrum adolfomorenoi belongs to the GROUP Diothonea SUBGROUP Diothonea, characterized by the branching habit, the leaves linear-lanceolate to lanceolate, bilobed at the apex, the arching-nutant, racemose inflorescence, the membranaceous or rarely fleshy flowers, the lip entire to 3-lobed with an erose margin, ecallose, without or with 1 to 10 thin, smooth to erose keels, and the column united to the lip ranging from totally to obliquely united to free. The species is recognized by the thin stems .08" [2 mm] thick, the linear leaves, the .8 to 1.6" [2 to 4 cm] long inflorescence, the 4 to 6 creamy-white flowers striped with violet, the column, .24 to .4" [6 to 10 mm] long is arching strongly upwards beyond the middle, thick, with a pair of truncate wings at the apex, the lateral sepals .38 to .44" [9.5 to 11 mm] long, connate at the base, petals connate with the dorsal sepals, the lip widely ovate with 5 smooth keels on the disc. Epidendrum cryptotropis Hágsater, Collantes & E.Santiago has very similar flowers in color and size, but the column is .2" [5 mm] long, slightly arched downwards, the lip is entire, sub-pandurate, flat in natural position, and the petals are spreading, oblong, straight. Epidendrum cochabambanum Dodson & R.Vásquez has smaller flowers, the sepals free, .16 to .28" [4 to 7 mm] long, the lip transversely elliptic with the apex 4-lobed, and the column has a deltoid, ventral slit .16" [4 mm] long. Epidendrum gastrochilum Kraenzlin has an .1 to .14" [2.5 to 3.5 mm] long inflorescence, 3 to 5, greenish brown flowers, free sepals .44 to .6" [11 to 15 mm] long, and the lip ovate-orbicular with 6, laminar, erose keels."
