OBCHIDS OF MABAGASCAB. 509 



margins. The lip is three-lobed, the middle lobe the shortest and 

 bluntest; the laterals narrowly linear acuminate, minutely pu- 

 bescent. The spur is filiform, slightly dilated before the tip, about 

 as long as the ovary (5 lines). The base of the anther is pro- 

 longed in the form of two short processes, which bear the slender 

 caudicles. The stigmatic lobes are rather long, straight, and 

 blunt, projecting over the entrance to the spur. The gland of 

 the caudicles is minute, circular.
