Sumatra: Padangsche Benedenlanden, GoenoengTalamau, north-vvest 

 slope, 2050 m., epiphytic in forest. (H. A. B. BuNNEMEljER n. 788, May 

 1617); west slope, 2700 m. (H. A. B. BiiNNEMElJER n. 856, May 1917). 



Pfitzer w^ould place this in his subgenus Aphanosfelidiiim. It is appa- 

 rently near D.glossorhynchiini SCHLTR., but with much larger flov^ers, broadly 

 ovate bracts, an erose lip with a relatively broader midlobe. 



In n. 788 the column was nearly entire, whereas in n. 856, the flowers 

 of which had already set fruit, it was provided with a tooth on each side 

 of the clinandrium. 



In the form of the lip the species much resembles D. cor nu tu m BL, 



The flowers are said to be light green or green.
