Found in Cusco department of Peru at elevations around 1600 meters as a small to medium sized, cool growing epiphyte with stems giving rise to stems towards the apex of the previous stem, and carrying 4, aggregate towards the apex of each stem, widely elliptic leaves that blooms in the summer on a terminal, drooping, few flowered inflorescence carrying rose purple colored flowers.

"Epidendrum subreniforme C.Schweinf. is part of GROUP Arbuscula SUBGROUP Incomptum characterized by the successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, a short apical inflorescence with fleshy greenish to violet-green flowers with short ovaries, the lip entire to 3-lobed. The species has leaves three times longer than wide, to 1.84" [4.6 cm] long, lip reniform in outline, .48 x 1.04" [12 x 26 mm], lightly contracted on each side, not 3-lobed, base widely obcuneate, apex apiculate. E molinae has widely elliptic leaves half as wide as they are long, the arching-nutant, densely many flowered inflorescence with green flowers, the sepals dorsally lightly tinged with purple, the oblanceolate, 3-veined petals and the wide, 3-lobed lip, the lateral lobes obliquely sub-quadrate, and small mid-lobe transversely rectangular, twice as wide as it is long, short-apiculate. Epidendrum incomptum Rchb.f. has the mid-lobe as long as it is wide, and the lateral lobes of the lip are forward positioned, more or less triangular, so that the base is truncate, not cordate, flowers are dark green and ecallose. Epidendrum platyglossum Rchb.f. has unequal, long, narrow, acute leaves, 2.8 to 4.6" x .52" [7 to 11.5 x 1.4 cm], acute tepals, the lateral sepals prominently aristate, and the deeply cordate lip with the lateral lobes somewhat larger than the mid-lobe which is obcuneate, bilobed and retuse. Epidendrum envigadoënse Hágsater, also found in the same general area, has narrower leaves, fewer flowers, wider, obtuse petals, a clearly 3-lobed lip .7 to ,76" [17.5 to 19 mm] wide, the lateral lobes obliquely elliptic, the midlobe somewhat larger, emarginate, forming two semi-orbicular lobes."
