Found in southern Ecuador to northern Peru in wet montane forests and elfin forests at elevations around 1700 to 1950 meters as a medium sized, cool growing epiphyte with ellipsoid, striate pseudobulbs carrying a single, apical, plicate, stiff coriaceous, lanceolate, acute leaf with a terete petiole that blooms in the winter and very early spring on a basal, erect, 4" [10 cm] long, loosely 8 to 10 flowered, racemose inflorescence enveloped basally by close, loose, sub-inflated, clear brown bracts and longer than the ovaries floral bracts . This species is distinguished from others by the unlobed, elliptic labellum and the low, oblong callus that is dentate apically and extended in the front with 5 verrucose ribs.
