Found from the central cordillera of Colombia to southwestern Ecuador at elevations of 460 to 2100 meters as a miniature sized, warm to cool growing epiphyte with erect, slender ramicauls enveloped basally by 3 to 7 minutely scabrous, lepanthiform sheaths and carrying a single apical, erect, coriaceous, elliptical, obtuse leaf that is cuneate below into the petiole that blooms in the spring and fall on a fascile of loose, simultaneously 1 to 3 flowered, .4" [1 cm] long, racemose inflorescence arsing from near the apex of the ramicaul.

"Distinguished by the short, few flowered racemes of pale yellow flowers with acute sepals and subacute petals. The lip is thick, arcuate, oblong with erect margins below the middle. The middle third of the disc is filled by a pair of thick, semilunate calli. Most distinctive is a pair of nipple-like calli on the under side of the column." Luer 1997
