An aquatic herb, submerged all but the inflorescence. Stolons stout, much 

 branched and often very long. Leaves l|-3 in. lung, usually in whorls of 

 4 ; segments filiform, pectinate, each pinna usually bearing at its base a 

 small subglobose bladder which becomes black by age. Racemes erect, 

 3-8-flowered ; peduncles up to 9 in. long, rather stout, naked or with a 

 few small scales, but with no whorl of floats, the whorl of leaves however 

 at the base of the peduncles has often its rhachis more or less inflated 

 and thus acts as a float ; bracts small, ovate ; pedicels £-§ in. long, 

 deflexed in fruit. Calyx §-g in. long ; lobes subequal, ovate, obtuse or 

 subacute, somewhat enlarged in fruit. Corolla yellow, |-| in. across; 

 spur nearly as long as the lower lip. conical, acute. Capsule subglobose, 

 ^ in. long. Seeds as in U. stellaris but rather larger.
