with the leaves cut into capillary segments and often furnished with . 

 minute bladders. Fls. solitary or racemose on the scape, bracteate 

 and often 2-bracteolate. Calyx 2-partite, lobes entire or nearly so, 

 often accrescent. Seeds ellipsoid or obovoid, scrobiculate or glochi- 

 diate, rarely reticulate or comose. 



Clarke states that some of the small scapose species with evanescent radical 

 leaves on very short creeping branches maj' possiblj' sometimes grow in running- 

 water and produce elongate branched stems, longer linear leaves and reduced, 

 leaves with bladders. 



The bladders of many, if not all the species which bear them, are adapted for the 

 capture and digestion of minute aqiiatic animals. Bladders or recepts adapted tor 

 the capture of animalcula? are also found in the place of the leaves or on the under- 

 side of the leaves in many land forms. 

 I. Aquatic with elongate stems and very numerous multifid 

 leaves. Pedicels stout in fruit. Capsule globose :— 

 Large floating vesicles '8" long round base of scape. Fruiting 



sepals "3-'i" long. Fls. yellow 1. sfellaris. 



As above, but flowers white purple-streaked .... var. infiexa. 

 Large vesicles not present, but very numerous bladders. Fls. 



yellow. Fruiting sepals •2-"27" 2. ftexiiosa. 



II. Semi-aquatic with sparse filiform leaves and minute bladder- 

 bearing branches. Scape slender 2-3-fld. :— 

 Fls. yellow. Pedicels slender. Capsule globose . . .3. exoleta, 

 III. Leaves simple at base of scape, obsolete at time of flowering. 

 Erect or twining :—

1. U. stellaris, L.f. 



A beautiful little aquatic with the stems floating for several feet, 

 many capillary leaves and racemes of yellow-lipped flowers surrounded 

 towards base by a whorl of large floating narrowly-ellipsoid vesicles 

 •7-"9" long. Bladders on the leaf segments very minute. Eacemes 

 flexuose 2'5-4'''. Fls. -25". Fruiting sepals •3-"4" long, decurrent 

 into the short often deflexed •1-25 pedicel. 



Purneah ! Said to be found throughout India and therefore probably also in 

 other districts. Fl., Fr. c.s. 



A verj' distinct species. Leaves 1-2" flaccid when removed from the water about 

 5-fid from the base, each segment cut into capillary lobes. The floating vesicles 

 appear to be modified leaf rhachises and end in capillary leaf-lobes ; thej^ support 

 the inflorescence above the water. Sepals ovate glabrous "22" in flower. Lower 

 lip of corolla with a projecting transverse j-ellow lamella and rounded yellow 

 labellum with brown strijies at the margin, upper lip with concave base thickened 

 round the edge and yellow margin with brown lines, spur obtuse green with brown 

 lines. 



A variety inflexa, Clarke, with white and violet striped corolla is said to be common. 



2. U. flexuosa, Valil. 



Somewhat similar to the last in inflorescence but ^vithout the large 

 floating vesicles at base of peduncle. Short lateral branches of stem
