Found in Costa Rica at elevations of 800 to 1800 meters in open woods and pastures on trunks and main branches as a warm to cool growing epiphyte with ovate, laterally compressed, ancipitous pseudobulbs partially enveloped basally by several pairs of distichous, imbricate leaf-bearing sheaths and carrying a single, apical, erect, oblong-lanceolate leaf that is conduplicate below into an elongate, petiole-like base that blooms in the fall and winter on an axillary, 10 to 36" [20 to 90 cm] long, shortly paniculate, several to many flowered inflorescence with each branch carrying 2 to 4 flowers.

Often cited as a synonym of O obryzatum but differs in the much larger flower with a large, round to sheild shaped, lip base and in the calli.
