tropical America. The corolla is always rcilucetl to one petal, (lie 

 anterior one. The androceum also generally consists of only one 

 fertile st mien ; but the number of ovules in one cell is more than 

 two. In CalUsthene (flg. 132-184), the capsular fruit has a thick 

 columella, which persists after the fall of the valves. In Qualea, 

 the columella is wanting or scarcely developed. The ovary cells are 

 often incomplete ; the ovules, disposed obliquely in two rows at the 

 back of the placentas, are incompletely anatropous or almost ortho- 

 tropous, and already surmounted by a wing-shaped dilatation still 

 more manifest in the seeds. The posterior spur is sometimes reduced 

 to a very small size.
