Found in Ecuador in cloud forests at elevations of 1800 to 2700 meters as a miniature sized, cool to cold growing epiphyte with slender ramicauls enveloped basally by 2 to 3 loose, tubular sheaths and carrying a single, apical, erect, coriaceous, long-petiolate, elliptical, obtuse leaf that is cuneate below into the slender petiole that blooms in the late winter and early spring on an erect then almost horizontal, congested, simultaneously several-flowered, racemose, 8" [20 cm] long inflorescence arising from low on the ramicaul with 3 to 4 evenly spaced, tubular bracts and, thin, oblique, acute, cucullate floral bracts.
