Parana.] oi. coNVOLTULACEiE. (C. B. Clarke.) 221 



Throughout India and Cetlon, very common ; rare in very damp regions, — 

 DiSTHiB. The tropical and subtropical area of the glohe. 



Perennial; annual branches numerous, wiry, often prostrate. Leaves j-1 in., 

 rarely IJ by | in., very variable ; petiole 0-^ in. Pedimcles ^1| in. ; bracts small, 

 linear, hairy, persistent ; pedicels 0-^ in. Capsule ^ in., globose, 4-valved. — The 

 commonest Indian form is the type with leaves ^-^ in., oblong or elliptic, moderately 

 silky with white or fulvous hairs. E. linifolms (E. angustifoUus, Boxb.), has linear 

 leaves often 1 in. long. E. hirsutm, has thick leaves and is more or less densely 

 hirsute -ypith fulvous or rufescent hairs.

 flower small, narrow ; in fruit all or 3 much enlarged, scarious, nerved. Corolla 

 campanulate or funnel-shaped, wide- or narrow-mouthed ; limb 5-plaited, sub- 

 entire or lobed. Stamens subincluded, filaments filiform or shortly linear. 

 Ovary 2-celled, 4^ovuled ; style long or short, entire with a simple or 2-lobed 

 stigma, or 2-fld with capitate stigmas. Capsule globose oblong or obconic, 

 membranous, indehiscent or 2-valved, 1-seeded. Seed glabrous; cotyledons

An extensive, rather slender, glabrous or pubescent climber. Leaves 5 by 2| in., 

 young villous beneath, old glabrous or puberulous on both surfaces ; petiole 3 in. 

 FeduTicles 3-4 in.; racemes 2-3 in., 4-12-fld. ; bracts \ in., linear; pedicels j- in. 

 Sepals ^ in., linear-oblong, puberulous. Corolla mUuve ; tube f-l in., linear ; limb 

 funnel-shaped, subentire. If in. diam., glabrous. Stamens and pistil \-\ in., included 

 in the small swollen base of the corolla^tube. Style linear, stigma subglobose. Cap- 

 sule ^ in., subglobose, rather longer than broad; 3 larger fruiting sepals subpal- 

 mately 7-9-nerved ; 2 smaller, 1 by | in. 



2. P. stenoloba, Kurz in- Trimen Jowm. Bot. 1873, 136; nearly 

 glabrous, leaves ovate slightly cordate caudate-acuminate, racemes long-bracted, 

 sepals all much enlarged in fruit, 3 more than the others 1 by ^ in. 



Tempeeate Slkkim, alt. 5-6000 ft. ; on rocks by the Daijeeling road, not un- 

 frequent, Kurz. 



Nearly allied to P. grandijlora. Leaves very shallowly cordate, caudate, glabrous 

 or minutely hairy above. Bracts 1-1^ in., ovate-lanceolate, or lanceolate caudate, 

 often petioled ; bracteoles 2, minute. Corolla (dry) nearly as of P. grandijlora, but 

 " steel-blue," Kitrz ^ King. Capsule not ripe ; 3 larger sepals in fruit membranous, 

 6-nerved; 2 smaller similar, but | less. — This differs from P. grandiflora in the 

 shallowly cordate leaves, the remarkable bracts, the colour of the flowers and the 

 exceedingly narrow fruit-sepals; but in Gen. PI. ii. 876 it is considered con- 

 specific. 



3. P. spectabills, Kurz in Trimen Joum. Bot. 1873, 136, and For. Fl. 

 ii. 221 ; fulvous-tomentose, leaves subcordate ovate-oblong, racemes sub- 

 ebracteate, 3 sepals greatly enlarged in fruit 1 J by J in. 2 altogether suppressed, 

 P. speciosa, Benth. in Gen. PI. ii. 876.
