W. Med. — In several of the drains and ditches in the marsh at Freshwater 

 Gate, hut never seen by me in flower. Ditches in the marsh at Easton, plenti- 

 fully, Fl. Vect. .'!.' 



I have observed that the stems float about in the water unconnected by any 

 root or visible means of communication with the soil, a fact since confirmed by 

 the Bev. W. H. Coleman, who supposes that the extremities of the branches 

 detach themselves in early spring, and continue increasing in length through the 

 summer, as they are at first not above an inch or two in length and without 

 bladders. 



2. U. minor, L. Lesser Bladderwort. " Spur obtuse keeled 

 deflexed much shorter than the corolla, the upper lip of which is 

 notched and as long as the palate, lower lip obovate nearly flat, leaves 

 subtripartite, the segments linear dichotomous glabrous, vesicles 

 attached chiefly to the leaves."— Br. Fl. p. 327. E. B. t. 254.
