Flower Size .08" [2 mm]

Found in Risaralda department of Colombia at elevations around 2400 meters as a mini-miniature sized, cold growing, densely caespitose epiphyte with erect, slender ramicauls enveloped by a tubular sheath at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, subacute, gradually narrowing below into the base leaf that blooms in the later spring on a single, from a node at the apex of the ramicaul, peduncle .08" [2 cm], rachis to 1.6 to 2.4" [4 to 6 cm] long, erect, flexuous, distichous, mostly simultaneously many flowered inflorescence with oblique, acute, just shorter to as long as the ovary floral bracts and carrying flowers with yellow-green sepals, tan petals and a purple lip.

"This little, caespitose species is characterized by ramicauls shorter than elliptical leaves; an erect, delicate, flexuous, successively many-flowered raceme far exceeding the leaves; broad, yellow-green, minutely papillose, or cobble-stoned sepals; thin, single-veined petals; and a subquadrate lip with a large, low callus surrounded with a moat-like cavity within the margin."
