Found in Antioquia department of Colombia at elevations around 2050 meters as a miniature sized, cold growing, densely caespitose epiphyte with erect, very slender ramicauls enveloped by a close tubular sheath below the middle and another above the base and carrying a single, apical, erect, coriaceous, narrowly linear-elliptical, acute, gradually narrowing below into the ill-defined petiolate base leaf that blooms in the later spring on 2 to 3, from a node at the apex of the ramicaul, peduncle less than .4" [less than 1 cm] long, rachis to 2.4 to 3.2" [6 to 8 cm] long, erect, crowded disitchous, mostly simultaneously many flowered inflorescence with oblique, subacute, shorter than the ovary floral bracts and carrying light yellow flowers.

"This species is characterized by two or three densely many-flowered racemes that are slightly shorter than, to slightly longer than narrow, linear-elliptical leaves. The dorsal sepal is erect, ovate and subacute, while the longer, acute lateral sepals are antrorse. The petals are thin and faintly single-veined. The lip is ovate and concave with involute sides. The bar is a transverse callus across the base. The apex is acuminate into a sharp point." Luer 2016
