Found in Costa Rica and Panama in cloud forests at elevations of 400 to 1400 meters as a small to medium sized, warm to cool growing epiphyte with slender, complanate, cylindric pseudobulbs enveloped totally by imbricate, conduplicate leaf bearing sheaths and carrying a single apical, oblong-ellipitic, acute apically, conduplicate into the petiolate base leaf that blooms in the summer and fall on many, basal, 3" [7.5 to 10 cm] long, single flowered inflorescence enveloped by obtuse, apiculate bracts and carrying sweeetly scented flowers.
