'1 he delicate stems and leaves, with the small bladders (adapted for 

 the capture of minute animals), from which the genus takes its name, are 

 commonly overlooked in the land forms in consequence of their fugacious 

 character. They are described and figured in all our species (except 

 U. capillacea) in Goebel's memoir in 'Ann. Jard. Buitenzorg,' ix. (1891), 

 which was worked out partly from Ceylon material.

Stems submerged, often very long, slender, slightly 

 branched ; 1. all submerged, very numerous, closely placed, 

 apparently in whorls of 4, \\-2\'\n., pinnately cut into 

 numerous filiform very slender pectinate segm. each provided 

 near the base with a small globular-ovoid bladder ; fl. few, 

 on short ped., in erect axillary racemes, peduncle long, pro- 

 vided below the infl. with a whorl of 4-8 sessile, large, oblong- 

 ovoid, acute, spongy floats which support the fl. above the 

 water ; bracts short, no bractlets ; sep. ovate, obtuse, veined ; 

 cor. \ in. diam., spur a little shorter than lower lip, blunt, 

 curved, fruit not seen. 



In rather deep water, tanks, &c. in the dry district ; common. Moon's 

 locality is Jaffna. Fl. throughout the year; yellow. 



Throughout the Tropics of the Old World. 



The plant is omitted in Thw. Enum. The floats are, doubtless, 

 modified leaves or bracts.
