 stems sparsely liirsute, leaves ovate-oblong cordate or subhastate sinuate irregu-

Stems, annual, twining. Leaves 1-2 in., scabrous or sparsely hirsute; petiole 

 1 J in. Pedtmcles 0-J in. ; bracts J in., linear, subperaistent ; pedicels ^-^ in. Sepals 

 J in., acute, 'widened in fruit. Corolla ^-^ in., campanulate, white when dry, Visiani, 

 probably yellow when fresh. Capsule J in. and upwards, ovoid, glabrous, usually 

 4-seeded. Seeds velvety. 



30. X. obscura, Ker in Sot. JReg. t. 239 ; leaves ovate-cordate acute 

 entire nearly glabrous, peduncles long laxly 1-3-fld., sepals ovate subacute 

 nearly glabrous, coroUa middle-sized ochroleucous with a purple base, seeds 

 velvety. Chois. Convolv. Or. 82, and in DC. Prodr. ix. 370, some syn. excl. ;

 Mascarene Islands, E. Africa. 



Stems twining, hairy or nearly glabrous. Leaves 1-2J in. ; petiole 1-2 in. 

 Fedv/ncles 1-3 in., often 1-flowered, rarely with so many as 3-flowers ; bracts ^ in., 

 lanceolate, subpersistent ; pedicels \-l^ in. Sepals J in. ; ultimately broader, obtuse, 

 reflexed. Corolla f-1 in., tnbe narrow, mouth wide, glabrous, yellow or white with 

 the plaits yellowish, always with the purple spot at the base. Anthers never twisted. 

 Capsule :J-J in., ovoid, subacute, glabrous, 2-valved, 2-seeded, normally 4-seeded. 

 Seeds densely softly brown-velvety ; therefore the Indian species is not the /. obscwra 

 elaborately described by Hasskarl (PI. Jav. Bar. 519). 



Vak. gemella ; adult leaves closely hairy on both surfaces. Convolvulus gemellus. 

 Wall. Cat. 1383 type sheet, not of Vahl. — Bengal; Wallich, &c., frequent. — Ipomsea 

 gemeUa, Chois. Convolv. Or. 87, and in DC. Prod/r. ix. 380, consists of Convolvulus 

 gemellus, Bwrm. Fl. Ind. 46, t. 21, fig. 1 (a Javan plant) and the totally different 

 C. affinis. Wall., from E. Bengal and Burma ; so far as any Malabar examples are 

 supposed to be /. gemella, they are perhaps L obscura. 



31. I. Stocksii, Clarke; leaves ovate-lanceolate cordate subcaudate 

 shortly hairy on both surfaces, peduncles long laxly 1-3 fld., sepals lanceolate 

 acuminate, corolla somewhat large, seeds glabrous. 



Malabar and Concan ; Slocks, Law, &c. 



Resembling generally (when dry) /. obscwra. Leaves 3g in., deeply cordate, finely 

 acuminate. Pedicels often 1-^ in. Sepals J in., in flower sublinear, in fruit lanceolate, 

 sparsely hairy. CoroUa (very much withered) exceeding 1 in. Capsule nearly J in., 

 ovoid-oblong, glabrous, 4-valved, 4-seeded. — Eeferred in Herb. Ind. Or. H. f. ^ T. 

 possibly to a var. of /. obsoura, which the large flowers and glabrous seeds will not 

 admit. From the unusually narrow sepals it may be the Malabar plant which 

 Willdenow (and Choisy) have placed with Surmann's Convolvulus gemellus. 



32. X. sibirica, Pers. Syn. i. 183; nearly glabrous, leaves triangular-lan- 

 ceolate cordate entire or undulate, peduncles shorter than the petioles 1-4-fld., 

 sepals ovate mucronate, corolla small white, seeds glabrous. Chois. in DC.
