BY E. D. MERRILL. 531 



A species strongly marked by its unusually large starainate 

 flowers, the sepals being about 2 cm in diameter, and its 

 large obtriangular capsules which are gTadually narrowed 

 from the rounded outer corners of the wings to the cuneate 

 base, two of the wings being larger than the other one but 

 with the same general shape. The capsule proper is subor- 

 bicular in outline, apparently dehiscing close to the wings, 

 the wings being extended both below and above it. The apex 

 of the entire fruit is somewhat reentrant-truncate, not straight 

 across the top. The torus bearing the stamens is about 5 

 mm long.
