Avithin with stigmatio papillte. In the inner 

 angle of each cell is inserted a descendent ana- 

 tropous ovule, with exterior and superior micro- 

 pyle, capped by an obturator. The fruit is 

 capsular, dehiscing in three bi-valve and mono- 

 spermous shells ; and the cxarillate seed contains 

 under its coats an abxmdant fleshy albumen at 

 the centre of which is an embryo
