The species is characterized by the epiphytic, pendulous, sympodial habit, the stem with a homoblastic pseudobulb, terete, constituted by 3 internodes, green, smooth, brilliant, the leaves lanceolate, mucronate, the lip deeply 3-lobed, with 2 prominent calli, upright, and with 3 prominent thickened ribs, the lateral ones in front of the calli, smaller than the mid-rib. Epidendrum pachydiscum Hágsater, described from Cusco Province, is overall very similar, though it has erect stems, the lip is ecallose, and the lateral lobes of the lip are much wider.
