Found in Choco' department of Colombia at elevations around 400 meters as a mini-miniature sized, hot growing, caespitose epiphyte with erect, slender ramicauls enveloped by a loose tubular sheath below the middle and another at the base and carrying a single, apical, coriaceous, narrowly linear-elliptical, acute, gradually narrowing below into the base leaf that blooms on 1 to 2, erect, arising through a spathe from a node at the apex of the ramicaul, peduncle 1.2 to 2" [3 to 5 cm] long, rachis 4 to 4.4" [10 to 11 cm] long, erect, loose, distichous, mostly simultaneously many flowered inflorescence with tubular, obtuse, shorter than the pedicel floral bracts and carrying light yellow, glabrous externally, sparsely pusticular within flowers.

"This slender, densely caespitose, little species from a low altitude of the Western Cordillera is distinguished by narrow leaves and shorter ramicauls with loose sheaths. One or two loose, weak, many-flowered racemes far exceed the leaves; the obtuse sepals are sparsely pusticular within; the petals are thick and three-veined; and the type A lip is obtuse, the bar with a glenion."
