Sect. b. Eu-Platycentbttm. Capsule dehiscing by an elliptic 

 line round the narrow face ; and also simultaneously by a line on 

 each of the broad faces adjacent to the narrow wings. Not rarely 

 this line is ultimately continued into a complete ellipse on- each 

 of the broad faces, which then, being quite free, fall off as valves. 



This section appears at first sight sharply separable from the 

 Elastic® ; but the first species, B. xanthina, is in fact almost in- 

 termediate between Sect, a and b ; and in this species, too, the 

 narrow face is inclined to split out entirely from below as in 

 B. gigantea.

The foregoing account of the Indian Begonias will be found to 

 differ from that in the ' Flora of British India ' in one point, viz. 

 the statements regarding the dehiscence of the capsule. In the 

 typical species with three cells to the capsule, I describe the " de-
