BEGONIACEtE.

the male plant is known. If rightly referred to the B. luxurians, 

 briefly characterized by Scheidweiler, it is a smoother form of that 

 species, the leaves, &c, not being hispid. Some of the numerous 

 leaflets, moreover, are bisected or trisected. The (male) flowers are 

 small, and crowded in a compound corymbose panicle, which is very 

 long-peduncled.

Hab. Near Rio Janeiro. 



A large and coarse species, apparently not uncommon near Rio 

 Janeiro, where it was gathered by Pohl, and by Gardner (No. 608). 

 I refer our plant to this species from the appropriateness of the name 

 to the ramentaceous petioles; the work in which B. ramentacea is 

 figured not being within my reach.
