U. barbata, R. Br. Prod. 432 ; A. DC. Prod. viii. 16, from Queensland, Banks and So-

 that I cau identify with it, nor indeed any iu which I can discover the palate to be hairy or 

 bearded as described. 



U. nompressa, R. Br. Prod. 431 ; A. DC. Prod. viii. 15, from Queensland, Banks and

 no specimen is preserved cither in the Banlisian or in Brown's herbarium.

1. U. stellaris, Linn. /. ; A. DC. Prod. viii. 3. Stems floating, 

 brauclied, extending to a considerable length. Submerged leaves root-like, 

 branching into numerous capillary segments interspersed with little globular 

 vesicles. Peduncles slender, 2 to 4 in. long in the Australian specnnens but 

 longer in some Indian ones, bearing at some distance below the raceme a 

 cluster or almost a whorl of 3 to 5 oblong or narrow vesicles each about | iii. 

 long, tapering at both ends, and bearing a few short simple or branched capil- 

 lary segments. Flowers several, vellow, on pedicels of 2 to 6 lines, which 

 are slender at the time of flowering, often thickened under the fruit, and then 

 spreading or reflexcd. Calyx-segments ovate and about 1 Ime long m 

 flower, broad and 2 lines diameter in fruit. Corolla upper lip ovate or 

 rounded, obtuse, lon-er than the calyx, lower lip nearly orbicular, scarcely 

 longer than the upper one, truncate or slightly 3-toothed ; spur turned up- 

 wards under the lower lip and about its length. Capsule nearly as long as 

 the calyx, membranous. Seeds peltate, with an angular margin —Uiiv in
