Found in Amazonas state of Venezuela and Brazil in the Cerro Neblina at elevations around 1800 meters as a medium sized, cool, monopodial, pendent growing epiphyte with branching, flexuous, secondary stems arising from the intermediate nodes of the primary stem, tertiary branches arising the from the intermediate nodes of the secondary stems, terete basally, laterally compressed towards the apex stems enveloped basally by scarious sheaths and carrying numerous in the primary and secondary stems, 6 to 8 on the tertiary stems, all along all the stems, distichous, unequal, basal ones smaller, narrowly ovate to lanceolate, narrowly bilobed, emarginate, coriaceous, margin entire leaves that blooms in the fall on a terminal, peduncle .04 to .08" [1 to 2 mm] long, enveloped by 2 imbricating bracts, single flowered inflorescence with shorter than the ovary, ovate, acute, conduplicate, membraneous floral bracts.

"Epidendrum cornurepens belongs to the GROUP Ramosum which is characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the SUBGROUP Repens, which has strictly pendent plants, with small leaves less than 1.36" [3.4 cm] long. The species has long plants, up to 24" [60 cm] long, with an evident primary and secondary stems, and short flowering branches; leaves on the primary and secondary stem are .8 to 1.36" [2.0 to 3.4 cm] long, while those of the flowering branches are .4 to .76" [1.0 to 1.9 cm] long, inflorescence has a single flower, sepals .32 to .36" [8 to 9 mm] long, lip .24 to .26" [6.0 to 6.5 mm] long, triangular narrowly cordate, apex acute, and the column has a pair of falcate, prominent apical wings. It is very similar in vegetative structure and flowers to Epidendrum repens Cogn. which is widely distributed from Mexico to northern Venezuela and the Lesser Antilles, and has smaller leaves and flowers, leaves to !" [2.5 cm] long, sepals .24 to .288" [6.0 to 7.2 mm] long, the lip .12 to .132" [3.0 to 3.3 mm] long, and lacks the evident apical, falcate wings at the apex of the column. Epidendrum brachyrepens Hágsater, endemic to middle Central America and the Larger Antilles, has short stems, no primary stem, leaves are all small and similar, .24 to .48" [6 to 12 mm] long, ovary is arched at the apex, sepals are .3 to .32" [7.5 to 8 mm] long, lip .152 to .2" [3.8 to 5.0 mm] long, and the column lacks any evident wings. Epidendrum strobiliferum Rchb.f., widely distributed throughout the neotropics, has much shorter plants, 8 to 12" [20 to 30 cm] long, smaller flowers, 3 to 5 per inflorescence, sepals -136 to .172" [3.4 to 4.3 mm] long, and the lip has a “Y” shaped callus. Epidendrum luckei Bock is endemic to the lowlands of the Darien and Chocó regions of Panama and Colombia with an inflorescence carrying 3 to 5 flowers, with a tridentate callus on the lip and the anther terminates in a pair of elongate horns."
