February 16, 1939. (Herb. Arn. Arb.; U.S. Nat. Herb. 1776073;

It would appear that Cunuria glabra is allied to C. 
Spruceana. Croizat (in Bull. Torr. Bot. Club 57 (1940) 
289) cited Pinkus 236 as representing Cunuria Spruce- 
ana. He pointed out, however, that the specimens ‘‘have 
slightly larger leaf blades which are truncate or fairly 
cordate at the base and larger capsules to 6 cm. long.”’ 
When sufficient material is amassed, it is at once evi- 
dent that Cunuria glabra is distinct from C. Spruceana. 
Besides the size and shape of the leaves, there are impor- 
tant differences in the texture and margin; in Cunuria 
glabra the leaves are extremely thick, coriaceous and 
very conspicuously marginate. The floral bracts are rela- 
tively large in Cunuria glabra, the flowers are extraordi- 
narily large, and the petioles are very thick and rigid.
