"E. microglossum Schltr. belongs to the GROUP Mancum SUBGROUP Maancum which is characterized by the sympodial habit, few-leaved stems, racemose inflorescence with 1 to 2 ancipitose, long, spathaceous bracts with parallel sides, and Mancum Subgroup which has non-resupinate, flowers, and a generally reduced, fleshy lip. The species can be recognized by the laterally compressed stems, lax-flowered inflorescence, flexuose rachis, spatulate petals, 3-lobed lip, the lobes semi-orbicular to transversely semi-elliptic, calli elongate with a thick mid-keel slightly longer, and the ovary incurved. Epidendrum microglossoides Hágsater & Dodson has terete stems, a straight rachis, single veined petals, margin dentate, lateral lobes of the lip bilobed, apex of the midlobe 3-lobed. Epidendrum microtum (Lindl.) Hágsater & L. Sánchez has longer, wider leaves, 2.4 to 6.28" x .72 to 1.4" [6 to 15.7 x 1.8 to 3.5 cm], the lobes of the lip are unequal, the lateral lobes very short, elliptic to sub-triangular, falcate, entire, the midlobe trapezoid, margin undulate. Epidendrum brachyglossum Lindl. has linear petals, the midlobe of the lip much reduced, transversely rectangular, entire. Epidendrum mancum Lindl. has wider, ovate-elliptic leaves, .52 to 2.08" [1.3 to 2.7 cm] wide, lip reduced, entire, sub-quadrate, the apex rounded." Hagsater etal 2009
