Found in Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Panama, the Windward Islands, Trinidad & Tobago, Fr Guiana, Surinam and Brazil in very wet and pluvial forests at elevations 50 to 1200 meters as a large sized, hot to cool growing epiphyte with a vine like stem carrying elliptic, coriaceous, acuminate leaves tht blooms in the winter on an axillary, .2 to .6" [.5 to 1.5 cm] long, 5 to 8 flowered inflorescence with triangular-ovate floral bracts.
