Found in the Molucca and Lesser Sunda Islands of Indonesia as a medium sized, perennial, herbaceous, cool to warm growing epiphyte at elevations of 900 to 2000 meters with narrowly oblong, tridentate apically, deep green with pale green tesselate leaves occuring in pockets of humus on steep cliff faces with moderate shade with mist and condensation supplying water even in the dry seasons. It blooms in the winter and spring on an erect, purple, pubescent, 12 to 15" [30 to 37.5 cm] long, single flowered inflorescence with an ovate, subacute bract.
