Found in Cundinamarca and Santander departments of Colombia in upper elevation cloud forests at elevations of 2300 to 2400 meters as a small to medium sized, cold growing epiphyte with caespitose, broadly oval, ancipitous, slightly compressed pseudobulbs enveloped basally by 4 to 6, distichous, uppermost floiaceous sheaths carrying 2, apical, elliptic, shortly acuminate, conduplicate below into the base leaves that blooms in the later spring on an axillary, basall from the axils of the uppermost sheaths, arching to arcuate, loosely flexous, racemose, 6 to 10" [15 25 cm] long, 3 to 10 flowered inflorescence with appressed, scale like, shorter than the ovary floral bracts and carrying stellate to slightly campanulate flowers

CAUTION Often cited [Kew for one] as a natural hybrid and synomonous with O x adrianae but Stig Dalstrom, Guido Deburghgraeve and Carlos Uribe have concluded the same as Rolfe that this is a valid species and not a natural hybrid
