"Epidendrum colanense belongs to the GROUP Andean SUBGROUP Sumacoense, characterized by the monopodial branching habit, cane-like stems, branching sub-apically, the branches shorter than the main stem, leaves coriaceous to sub-coriaceous and fleshy flowers, the lip entire or 3-lobed. The species is recognized by the linear petals, falcate and somewhat expanded at the distal 1/3, the lateral lobes of the lip auriculate, the calli sub-globose and the disc with a semi-circular thickening in front of the calli, column .48" [12 mm] long, with short teeth on each side. Epidendrum pichinchae has linear-lanceolate or linear-oblong petals oblique at the base, the lateral lobes of the lip are obliquely ovate to dolabriform, calli laminar, column .24 to .28" [6 to 7 mm] long, and the apex of the column has a pair of prominent sub-rectangular wings. Epidendrum sumacoënse Hágsater & Dodson has somewhat smaller flowers, sepals .52 to .6" [13 to 15 mm] long, oblanceolate petals with a rounded apex and erose margin, the lateral lobes of the lip obliquely ovate, and the column is .24" [6 mm] long with a pair of very prominent, rounded wings."
