Sumatra: Agam, Boekit Batoe Banting. (A. V. Theunissen, cuit, in Hort. 

 E. Jacobson, Fort de Kock, sub n. 112S; W. Groeneveldt, cuit, sub n. 

 1166). 



This is the first species of the section Dialeipanthe recorded from 

 Sumatra. The flowers resemble tliose of B. Stella Ridl., B. attemiatum 

 ROLFE, B. piigiunifornie J. J. S. etc., but the lip has distinct side lobes like 

 in B. ampkbracteatum T. et B. The petals are much shorter than broad. 



The same or a nearly allied species occurs on the Mentawei-islands, 

 where it was collected by captain J. F. K. Hansen; I did not see flowers.
