Found in Risaralda department of Colombia at elevations around 2400 meters as a small sized, cold growing, caespitose epiphyte with erect, slender ramicauls enveloped by a tubular sheath below the middle and 1 to 2 others below and at the base and carrying a single, apical, erect, coriaceous, narrowly linear-elliptical, acute, cuneate below into the petiolate base leaf that blooms in the later spring on a single, arising through a spathe from a node at the apex of the ramicaul, peduncle .8 to 1.2" [2 to 3 cm] long, rachis 3.6 to 4.4" [9 to 11 cm] long, erect, strict, distichous, mostly simultaneously many flowered inflorescence with tubular, obtuse, shorter than the ovary floral bracts and carrying glabrous flowers with a red-purple dorsal sepal and green lateral sepals and a green central apparatus.

"This slender species is distinguished by narrowly elliptical leaves with petioles nearly as long as the blade. A single, much longer raceme bears small, nutant flowers with an elliptical, red-purple dorsal sepal overlying a pair of smaller, green, connivent lateral sepals. The petals are single-veined, and the lip is type A with an obtuse apex and a round callus in the center of the dorsum." Luer & Escobar 2016
