 at the base. Capsule turbinate, opening by 3 valves, which are 



bipartite at the apex. 



1 S. BEGONi^FOLiA (Blum. 1. c.) stcm herbaceous, hairy; 

 leaves quintuple or septuple-nerved, obliquely cordate at the 

 base, acute, quite entire, ciliated, scabrous above, but beset with 

 small adpressed bristles beneath, those opposite each other 

 unequal in size, one of them almost sessile and heart-shaped ; 

 racemes axillary and terminal, many-flowered ; flowers sessile.

 beset with stiff hairs ; leaves 3-nerved, besides the marginal 

 nervules, oblong, acuminated, auriculately semi-cordate at the

petioles). D. C. prod. S. p. 166.

 apex. Anthers oblong, without auricles. Style filiform, not 

 capitate at the apex. Capsule baccate, 4-celled. Seeds ovate, 



angular? A Brazilian shrub, allied to Tococa, but differs in the 



bladders not being at the apex of the petiore but at the base, 

 apparently in place of stipulas, in the parts of the flowers being 

 quaternary, not quinary, in the calyx being at length bottle- 



unequal in size, one of which is cordate and sessile ; peduncles 

 axillary, few-flowered. ^ . S. Native of Java, on the moun-
