Calyx-leaves two, small, ovate, equal, permanent. Cor. rin-

 Stam. short, with small, cohering anthers. Germen glo- 

 bose. Stijle capillary, the length of the calyx. Stigma 

 2-lipped. Caps, globose, of 1 cell. Seeds numerous, small, 

 on a large, globular, central receptacle. 



Aquatic herbs, floating, in all our species, by means of blad- 

 ders attached to their stems or leaves, which latter are 

 finely divided. Fl. raised on a central stalk, above the 

 water; in ours racemose, yellow. New Holland abounds 

 with simple-leaved, fixed species, whosejlowers, as well as 

 those of many tropical Utricidaricc, are most generally blue.
