Probably a var. of L. setosa ; it differs in the capitate inflorescence and spreading 

 almost hispid backs of the sepals. 



11. L. setosa, Roxb. Hort. Seng. 13, and in Fl. Ind. i. 490, and ed. 

 Carey 8f Wall. ii. 80 ; leaves ovate-cordate acute or subobtuse sparsely hirsute 

 on both, surfaces, peduncles long, corymbs dense, bracts ^-^ in. ovate obtuse 

 adpressedly strigose persistent, sepals ovate or elliptic longer than the bracts 

 densely adpressedly strigose. Wight Ic. t. 1360. Convolvulus setosus, Watt.

A large climber; branches adpressedly strigose. Leaves 3-5 in., in age sometimes 

 nearly .glabrous ; petiole 1-3 in. Peduncles 2-8 in., stout, adpressedly strigose; 

 bracts coriaceous, very obtuse, at length deciduous ; corymbs 1-4 in. diam., dense, 

 but not capitate, branches thick. Sepals ovate, inner elliptic, very coriaceous, some- 

 what enlarged in fruit. Corolla 1^-2 in., densely setose without, rose-coloured. 

 Stam&ns included. Berry much more succulent than in L. strigosa, ovoid, subacute, 

 red, usually 4-2-seeded.

VAR. obovata ; leaves large 6 by 5 in. obovate obtuse or emarginate, fruit of L. 

 setosa. Convolvulus obovatus, Wall. Cat. 1381. Nepal ; Wallich. Eeduced to L. 

 elliptica by Choisy (DC. Prodr. ix. 330, under Argyreia), from which it is certain that 

 the true Convolvulus obovatus, now in the Wallichian herbarium, was not detected by 

 Choisy among Wallich's collections, which were placed loose in his hands. Several 

 species not found by Choisy appear to have been afterwards identified correctly by 

 Kippist, the Librarian of the Linnsean Society, in arranging the herbarium. 



12. Zi. atropurpurea, Clarke-, leaves elliptic-lanceolate cordate sparsely 

 hirsute on both surfaces, heads dense subsessile, bracts large oblong-lanceolate 

 persistent. Convolvulus atropurpureus, Wall. Cat. 1345, and Fl. Ind. ed. Carey

 lanceolate, herbaceous, softly hairy, lax in fruit. Corolla 1^ in., tubular- campanulate,
