Found in the Philippines in shaded areas at elevations of 300 to 900 meters as a small sized, hot to warm growing epiphyte in shade with oval pseudoobulbs carrying a single lanceolate leaf that blooms in the fall and winter on a basal, arching, many [50] flowered inflorescence that arises with a new growth.

CAUTION This species, D propinquum and D ecallosum are all very similar and I cannot separate them as there are no good drawings to go by, so please use with caution the determination above. I await better references.
