Found in Mexico, Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica as a medium sized, cool to cold growing, epiphytic species from montane forests at elevations of 1200 to 2600 meters with clustered, ovoid to ovoid-ellipsoid, compressed, ancipitous pseudobulbs enveloped basally by several, imbricate, distichous, membraneous, leaf-bearing sheaths carrying 2 to 3 apical, coriaceous, erect spreading, linear-ligulate , acute, leaves that blooms in the fall and winter with an erect to pendulous, to 4 3/4" to 20" [12 to 50 cm] long, raceme with 3 to 4 scarious bracts and triangular, scarious floral bracts that is shorter than the leaves arising on a mature pseudobulb with 4 to 10, fragrant, non-resupinate, long-lasting flowers.

They require cool to cold temperatures, even watering and fertilizer while in active growth, a fine grade medium and medium shade. This species inflorescence has a tendency to droop if not supported so tie it up to a stake in the medium so the flowers will be better presented.
