Found in the lowlands of Papua and New Guinea at elevations of 500 to 1500 meters on casuarina trees along streams and gullies as a small to medium sized, cool to hot growing epiphyte with narrowly fusiform, to 9 noded, purple brown or green stems carrying to 4 suberect, ovate, mostly concave of up side, coriaceous, slightly unequally biloped apically leaves that blooms on a 12" [30 cm] long, axillary, erect, several to many [to 10] flowered, racemose inflorescence with fragrant flowers arising from the nodes near the apex of both newly leafed and leafless canes occuring most often in the fall and winter but a secondary bloom is possible at any time of the year. A slight lessening of water and fertilizer in winter is beneficial for good blooming.
