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

 Rachmat n. 4S0, August 1913). 



This is the fourth species of the section Osyricera recorded 

 from Celebes. By its very thick deflexed spikes it is nearer to 

 B. mirabile Hall. f. from Bornéo than to the other species from 

 Celebes. The two short appendages at the base of the column 

 are very remarkable. 



Description from a scanty herbarium spécimen and an in- 

 florescence preserved in alcohol. 



The colour of the flowers is unknown.
