Found in Antioquia department of Colombia at elevations of 1600 to 1900 meters as a miniature sized, cool growing epiphyte with erect, slender ramicauls enveloped basally by 2 to 3 thin, ribbed, imbricating sheaths and carrying a single, apical, erecft, coriaceous, elliptical-obovate, subacute, narrows below gradually into the cuneate, petiolate base leaf and blooms in the fall on a strict, congested, to 18" [to 45 cm] long including the 2.4 to 3.2" [6 to 8 cm] long peduncle, successively many flowered inflorescence arising from low on the ramicaul with a bract below the middle and loose, oblique, as long as the ovary floral bracts.

"The inflorescence is very densely flowered, producing a compact cylinder of many flowers at the apex of a very tall, slender raceme. The raceme remains in flower for a long period of time as the lower flowers slowly faade, those above mature. The simple sepals and petals may be either purple or yellow, while the round lip is usually red." Luer 1990
