Fruit and Seed. Ovary of one to four carpels with as many 

 cells, but a three-celled condition is rare. Ovules pendulous, 

 anatropous, and solitary in each carpel. Fruit small and 

 nut-like or baccate, compressed, ribbed, angled, or winged, 

 one- to three-celled, indehiscent, or breaking up into as many 

 cocci as there are carpels. The testa is thin and mem- 

 branous, enclosing a copious layer of fleshy endosperm. The 

 embryo is somewhat cylindrical, straight, and almost equal 

 to the endosperm in length. The radicle is elongated and 

 stout, the cotyledons proportionately very short and blunt, as 

 in Hippuris vulgaris. In Gunnera scabra and other species 

 the embryo is minute, obcordate, and embedded in endosperm 

 close to the upper end of the seed. In Loudonia the seeds 

 are comparatively very large.
