Corolla (yellow ?) upper lip entire, lower with 1 broad lobe and 2 lateral 
narrow ones 6. U. pygmcea. 
Flowers yellow, several in a raceme. 
Pedicels very short, erect in fruit, not winged. Spur descending . . . 7. U. chrysantha. 
Pedicels as long as the calyx, reflexed, and more or less winged in fruit. 
Spur descending 8. TJ. bifida.

Calyx-segments rather acute 9. 17. cyanea. 
Flowers small, purple. Calyx-segments very obtuse. Flowers distant, 
on very short pedicels. Scapes 1 to 4in 10. V . lateriflora. 
Bracts produced below their insertion into a small free appendage. Flowers 
purple (or deep blue?). 
Pedicels opposite, in 1,2 or 3 pairs or in whorls of three. Corolla lower 
lip large, semicircular. Scapes erect, slender. Bracts opposite or in 
whorls of three. Spur shorter than the large semicircular lower lip. 
Upper lip entire or shortly 2-lobed 11. U. dichotoma. 
Flowers racemose, alternate as well as the bracts. (Flowers blue?). 
Pedicels as long as or longer than the calyx. Lower lip 2-lobed. 
Flowers £in. long or more. Spur longer than the lower lip . . . . 12. U. biloba. 
Flower scarcely 2 lines long. Spur shorter than the lower lip . . . 13. U. limosa.

1. U. stellaris (whorl of vesicles star-like), Linn, f.; A. DC. Prod. viii. 
8; Benth. FI. Austr. iv. 525. Stems floating, branched, extending to a con- 
siderable length. Submerged leaves root-like, branching into numerous capillary 
segments interspersed with little globular vesicles. Peduncles slender, 2 to 4in. 
long in the Australian specimens but longer in some Indian ones, bearing at 
some distance below the raceme a cluster or almost a whorl of 8 to 5 oblong or 
narrow vesicles each about iin. long, tapering at both ends, and bearing a few 
short simple or branched capillary segments. Flowers several, yellow, on 
pedicels of 2 to 6 lines, which are slender at the time of flowering, often 
thickened under the fruit, and then spreading or reflected. Calyx-segments 
ovate and about 1 line long in flower, broad and 2 lines diameter in fruit. 
Corolla upper lip ovate or rounded, obtuse, longer than the calyx, lower lip 
nearly orbicular, scarcely longer than the upper one, truncate or slightly 
3-toothed ; spur turned upwards under the lower lip and about its length. 
Capsule nearly as long as the calyx, membranous. Seeds peltate with an 
angular margin. — Oliv. in Journ. Linn. Soc. iii. 174; F. v. M. Fragm. vi. 161 ;

Hab.: Canon’s Creek, T. Gulliver. 
Common in tropical Asia, extending also into tropical Africa. 
2. U. flexuosa (flexuose), Void. ; Oliv. in Journ. Linn. Soc. iii. 175 ; Benth. 
FI. Austr. iv. 525. Submerged floating stems extending sometimes to several 
feet. Leaves all submerged and root-like, branching into numerous capillary 
segments, interspersed with little globular vesicles or utricles. Peduncles 
usually 3 to 6in. long, without vesicles, bearing a raceme of 3 to 6 yellow 
flowers. Pedicels erect and slender at the time of flowering, usually reflexed 
and thickened upwards when in fruit. Corolla fully 5 lines across, the upper lip
