Found in Norte de Santander department of Colombia at elevations around 2150 meters as a mini-miniature to miniature sized, cold growing, densely ascending-caespitose epiphyte with slender, erect ramicauls enveloped by a loose tubular sheath below the middle and 1 to 2 others below and carrying a single, apical, erect, coriaceous, elliptical, subacute, cuneate below into the petiolate base leaf that blooms in the later spring on an erect, arising from a node at the apex of the ramicaul, peduncle .6" [1.5 cm] long, erect, strict, rachis 1 to 1.2" [2.5 to 3 cm] long, successively few, several flowered inflorescence with oblique, acute, shorter than the ovary floral bracts.

"This very small, caespitose species is distinguished by elliptical, petiolate leaves only slightly exceeded by a strict, successively several-flowered raceme. The broadly obtuse sepals appear subcircular, the dorsal sepal, light green, and the lateral sepals, light purple. The ovate, singleveined petals are inserted obliquely to appear as a pair of wings protruding from behind the column. The type A lip is distinguished by a small, orbicular callus on the dorsum."
