stems sparsely hirsute, leaves ovate-oblong cordate or subbastate sinuate irregu- 

 larly angular or sublobate, peduncles short laxly few-fld., sepals elliptic-lanceo- 

 late patently hirsute, corolla very small. Convolvulus lasiospermus, Vis. PI.

MTS. of the S. DECCAN ; Travancore and Nilgherries, Bottler, Wight, &c. DISTRIB. 

 E. Tropical Africa. 



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

 1 in. Peduncles 0-| in. ; bracts | in., linear, subpersistent ; pedicels ^- ~ in. Sepals 

 I in., acute, widened in fruit. Corolla -% in., campanulate, white when dry, Visiani, 

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

 4-seedecl. Seeds velvety. 



30. Z. obscura, Ker in Sot. Reg. t. 239; leaves ovate-cordate, acute 

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



nettrly 'glabrous, corolla middle-sized ochroleucous with a purple base, seeds 

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

. Throughout INDIA and CEYLON, alt. 0-3000 ft.; common. DISTRIB. Malaya, 

 Mascarene Islands, E. Africa. 



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

 Peduncles 1-3 in., often 1-flowered, rarely with so many as 3-flowers; bracts^j- in., 

 lanceolate, subpersistent ; pedicels 5-!^ in. Sepals | in. ; ultimately broader, obtuse, 

 r0j&ed. Corolla f-1 in., tube narrow, mouth wide, glabrous, yellow or white with 

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

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

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

 elaborately described by Hasskarl (PL Jav. Ear. 519). 



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

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

 gemella, Chois. Convolv. Or. 87, and in DC. Prodr. ix. 380, consists of Convolvulus 

 gemellus, Burm. 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 I. obscura. 



31. Z. Stocksii, Clarke- leaves ovate-lanceolate cordate subcaudate 

 shortly hairy on both surfaces, peduncles long laxly 1-3 fid., sepal* lanceolate 

 acuminate, corolla somewhat large, seeds glabrous. 



MALABAR and CONCAN ; Stocks, Law, &c. 



Resembling generally (when dry) /. obscura. Leave* 3| in., deeply cordate, finely 

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

 sparsely hairy. Corolla (very much withered) exceeding 1 in. Capsule nearly i n ., 

 ovoid-oblong, glabrous, 4-valved, 4-seeded. Referred in Herb. Ind. Or. H. f. <f T. 

 possibly to a var. of I. obscura, 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 Burmann's Convolvulus gemelhts. 



32. Z. 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 J)C.
