Celebes: Goenoeng Pasangmalambe. (Exp. L. van Vuuren, 

 Rachmat n. 963, type, December 1913). Goenoeng Toemongah. 

 (Exp. L. van Vuuren, Rachmat n. 968, December 1913). 



This is near D. lanci/olium Rich., which is apparently a 

 common plant in Celebes, but, I think, speciflcally distinct. The 

 leaves are recurved above she base, the flowers larger with a 

 longer mentum, a mucb narrower lip with the midiobe much 

 more projecting. 



The material was rather scanty and the tlowers not in a 

 very good condition, so that it is possible that the description of 

 the keels on the lip is not wholly correct. 



The flower of n. 968 I examined had been injured by an 

 insect; it seems to differ slightly from n. 963. 



According to a note the flowers of n. 963 are red, those of 

 n. 968 light red.
