Fruit and Seed. The ovary is syncarpous, quite free from 

 the receptacle, and one-celled with three to five parietal pla- 

 centas denoting as many carpels. The ovules are numerous, 

 rarely few, pendulous, anatropous with a superior micropyle, 

 and ventral raphe, and arranged in one to numerous series 

 on the placentas. The funicle sometimes attains considerable 

 length, and usually becomes widened or dilated at the apex 

 forming a cup-shaped aril. The fruit is baccate or capsular, 

 indehiscent or dehiscing loculicidally, and usually containing 

 a large number of seeds. The latter are ovate or oval, much 

 compressed, rarely oblong, or much thickened, covered with a 

 fleshy or pulpy aril. The testa is leathery or often greatly 

 thickened, crustaceous, black and pitted or indented so deeply 

 in some cases that it forms small pointed processes projecting 

 into the endosperm. The latter is fleshy and scanty or 

 copious. The embryo is of large size, embedded in the endo-
