 rarely l by | in., very variable ; petiole 0- in. Peduncles -l in. ; bracts small,' 

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

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

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

1. P. grandiflora, Wall. Cat. 1324, and in Roxb. Fl. Ind. ed. Carey $ 

 Wall. ii. 41 ; shoots minutely pubescent, leaves ovate deeply cordate acuminate, 

 racemes minutely bracted, sepals all much enlarged in fruit, 3 more than the 

 others 1 by nearly \ in. obtuse. Chois. Convolv. Or. 108, and in DC. Prodr.

TEMPERATE NEPAL and SIKKIM, alt. 5-8000 ft. ; Wattich, Griffith, J. D. H., &c. 



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. 

 Peduncles 3-4 in.; racemes 2-3 in., 4-12-fld. ; bracts in., linear; pedicels in. 

 Sepals ^ in., linear-oblong, puberulous. Corolla mauve; tube -1 in., linear; liml- 

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

 in the small swollen base of the corolla-tube. Style linear, stigma subg'lobose. 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 Journ. Sot. 1873, 136; nearh 

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

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



TEMPERATE SIKKIM, alt. 5-6000 ft. ; on rocks by the Darjeeling road, not un- 

 frequent, Kurz. 



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

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

 often petioled; bracteoles 2, minute. Corolla (dry) nearly as of P. grandiflora, bu: 

 "steel-blue," Kurz $ King. Capsule not ripe ; 3 larger sepals in fruit membranes 

 5-nerved ; 2 smaller similar, but less. This differs from P. grandiflora in thi 

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

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

 specific. 



3. P. spectabilis, Kurz in Trimen Journ. Bot. 1873, 136, and For. /' 

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

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

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