Root somewhat creeping, with branched fibres. Stem erect, or

 Calyx of four ovate oblong spreading pieces, sub-membranous, ribbed. 

 Stamens numerous, pendulous, with slender capillary filaments, and 

 linear oblong anthers, of two cells, terminating in a point. Germens

This is an extremely variable plant in size, both of the stem and 

 leaves, and is either quite smooth or more or less scattered over with

 ovate, nearly an inch across, and much acuminated at the point. 



** Stamens erect.
