interposed ; the corolla tubular, 

 straight or curved, with valvate 

 lobes, glabrous or hairy within ; 

 anthers dorsifixed, enclosed or 

 exserted ; the two stigmatiferous 

 branches of the style are papil- 

 lose on their entire surface or 

 at the margin and interior face. 

 The ovary has two cells each 

 enclosing an erect or ascending 

 placenta attached to the partition 

 by a narrow point and bearing 

 an indefinite number of ascending 

 ovules. The fruit is a loculicidal 

 or septicidal capsule, that is 

 finally divided into fourpannelsj 

 and the seeds, peltate, com- 

 pressed or bordered with a 

 cellular wing, enclose a small 



albuminous embryo. They are herbs or shrubs of tropical or 

 subtropical America, with opposite or verticillate leaves, connate 

 stipules, and terminal corymbiform cymes.
