Found in Colombia and Ecuador at elevations of 3000 to 3600 meters as a medium sized, cold growing terrestrial with caespitose, ovoid pseudobulbs enveloped basally by 5 to 7 distichous sheaths and carrying 1 to 2, apical, erect, linear-elliptic to obovate, acute, conduplicate below into the subpetiolate base leaves that blooms in the fall on an axillary, erect to slightly arching, to 4' [120 cm] long, paniculate, with widely spaced, 2" [5 cm] long, 8 flowered side branches, many flowered inflorescence with adpressed, scale-like bracts.
