Found in Java and northern Borneo in lower montane forests at elevations around 1300 to 1900 meters as a cool growing epiphyte with numerous, grey, somewhat flattened roots that blooms in the winter on a bristley, 1.6 to 2" [3 to 5 cm] long, successively single flowered inflorescence carrying 6 to 15 mostly yellow but some with green flowers
CAUTION I have no way of verifying this determination so please use with caution. The second closeup photo is most likely wrong as it was submitted from New Caledonia.
