Sepals 3, oval or obovate, petaloid, imbricated in aestiva- 

 tion, persistent. Petals 3, hypogynous, alternate with the 

 sepals and similar to them, but more or less unguiculate, 

 with the base of the lamina auriculate on each side, imbri- 

 cated in aestivation, spreading, persistent. Stamens 6, shorter 

 than the floral envelopes and inserted opposite them, hypo- 

 gynous : filaments subulate : anthers oval or oblong, the 

 cells opening extrorsely lengthwise. Pistils 3, sometimes 

 2 or 4, sessile : ovary ovoid-oblong, one-celled : style short, 

 subulate : stigma terminal, depressed. Ovules usually 3, 

 and inserted one on the ventral suture, one on the dorsal, 

 and the third on some part of the wall of the cell near one 

 or the other suture, anatropous, pendulous. 



Fruit (one or two carpels ripening) indehiscent, coria- 

 ceous, pointed with the persistent style, 1-3-seeded. Seeds 

 pendulous, ovoid or globose ; the crustaceous testa cristate- 

 ribbed or echinate-roughened by the projecting ends of the 

 innumerable cells of which it is composed ; a mamillseforrn 

 portion at the hilum separates at maturity in the form of a 

 minute cap (doubtless serving to facilitate the protrusion of 

 the radicle in germination) : inner integument thin and 

 membranaceous. Albumen farinaceous, filling the cavity of
