In ditches and deep standing pools. 



Perennial. June, July. 



The crown of the root sends out 5 or 6, simple or alternately 

 branched, leafy shoots, about a foot long. Leaves alternate, 

 triply pinnatifid, almost capillary, bearing numerous crested 

 bladders, which float the plant at the flowering season, by means 

 of air formed within them. This air, according to Mr. Hayne, 

 gives place subsequently to water, and the plant sinks, to ripen 

 its seed at the bottom. FL 6 or 8, large, yellow, with an 

 orange-striped palate, and purplish stalks as well as calyx. 



2. U. intermedia. Intermediate Bladderwort. 



Spur conical. Stalk two- or three-flowered. Upper lip of 

 the corolla flat, twice as long as the palate. Leaves with 

 deep, forked, flat segments. Bladders separate from the 

 leaves.
