Found in Sabah, Borneo in hill and lower montane forests at elevations of 800 to 1700 meters as a small to medium sized, warm to cool growing epiphyte with a slender, subterete base, then strongly compressed, slightly fractiflex stems enveloped almost completely by distichous, imbricate, leaf bearing sheaths and each carrying equitant, laterally compressed, narrowly linear, falcate, decurved, obtuse to acute apically, coriaceous, rigid leaves that blooms in the winter, spring and fall on a arising from near the apex of the thin apical leafless stem with internodes, with pendant successively single flowered inflorescence held in fasciles arsing from the internodes.

In habit it is similar to D ventricosum and D macfarlanei of the SECTION Crumenata but has very different flowers. It differs from D smithianum in its longer leaves and in its very distinctive petals and lip. D calceolum has flowers that are large and differently colored.
