Found in Rondonia state of Brazil in Amazonian rain forest at elevations of 100 to 300 meters as a medium sized, hot growing epiphyte with clustered fusiform pseudobulbs that are enveloped basally by several deciduous leaf sheaths and carries 5 to 10, plicate, arched, oblanceolate leaves that blooms in the late spring and early summer on a basal, erect to suberect, several flowered, racemose inflorescence arising basally on a new pseudobulb lead.

This species needs a winter rest and enjoys moderate shade, even watering and fertilizing through its growth period
