Found in the eastern Cordillera of Colombia at elevations of 2,200 to 2,600 meters as a mini-miniature sized, cold growing epiphyte with blackish, slender, erect ramicauls enveloped basally by 2 to 3 loose tubular sheaths and carrying a single, apical, erect, coriaceous, elliptical, subacute to obtuse leaf that is cuneate below into the petiolate base leaf that blooms in the fall on a slender, erect, 2" [5 cm] long, single flowered inflorescence arising from low on the ramicaul, has a bract above the base and a tubular floral bract, all longer than the 1.6" [4 cm] long leaf.
