Celebes: Goenoeng Balapioe. (Exp. L. van Vuuren 1013, 

 Rachmat, liv. pi. cuit, in Hort. Bog. sub n. 132). 



Allied to B. unguiculatuni Rchb. f. but a more robust plant 

 with broader leaves, proportionally much shorter inflorescences, 

 larger tlowers, a différent lip and the column foot with a 

 large cal lus. 



It is perhaps still more closely allied to B. oligoblepharon 

 Schltr. from Celebes. This, however, lias according to the descrip- 

 tion narrower leaves, longer racemes, a ciliate lip. Moreover the 

 columnfoot in B. balapiuense bears a conspicuous callus, which is not 

 mentioned in Schlechter's description.
