Found only in Costa Rica in montane rainforests at elavations of 1100 to 2000 meters as a warm to cool growing epiphyte with cylindric, narrow, smooth, compressed speudobulbs enveloped basally by 3 to 7, oblong-lanceolate, foliaceous sheaths and carryinga single, apical, erect, linear-elliptic, conduplicate towards the base, thin, asymmetric, attenuate leaf that blooms in the fall through spring on a lateral, racemose to few branched panicle, 4 ot 12" [10 to 30 cm] long, successively flowered inflorescence.
