Found in Panama, Costa Rica and Nicaragua as a medium sized, hot growing epiphyte in deciduous forests of seasonally dry lowlands at elevations of 100 to 800 meters on trees overhanging slow moving rivers, streams and rills with small pyriform, sulcate, pseudobulbs enveloped by basal bracts with a single, coriaceous, ribbed, gradually narrowing below into the elongate, channeled petiolate base, elliptic leaf that blooms in the fall on a basal, 10" [25 cm] long, pendant, racemose, 2 flowered inflorescence arising on a mature pseudobulb with several, inflated basal sheaths carrying small fragrant Vicks vapo rub scented flowers for the genus.
