208 ci. CONVOLYULACEJ]. (C. B. Clarke.) [Ipomcea . 



Annual, twining. Leaves 3 by 2 in.; petiole 2 in. Peduncles ^- H in-; bracts 

 linear, deciduous ; pedicels ^1 in., racemose or subumbellate. Sepals \ in., glabrous. 

 Corolla f in., campanulate, glabrous, often yellowish near the base. Anthers never 

 twisted. Capsule %-^ in., ovoid, glabrous, 2-celled, 2-valved, 4-2-seeded. Seeds 

 ellipsoid, glabrous. The Indian specimen is rather more developed, both in leaf 

 and cyme, than the original Linnaean type, but is identical with the specimens col- 

 lected by Pallas. 



33. I. poranoides, Clarke ; glabrous, leaves ovate-lanceolate cordate 

 caudate entire, cymes peduncled many-flowerd lax, bracts ovate mucronate 

 persistent, sepals ovate obtuse unequal, corolla small white. 



SIKKIM and BEITISH BHOTAN ; alt. 3-5000 ft., frequent, Clarke. 



Scandent, twining. Leaves 3 by 2 in. ; petiole 1^ in. Peduncles 1-3 in. ; bracts 

 ^-f in., at the divisions of the divaricate cyme. Sepals \-^ in., glabrous. Corolla 

 f in., sub campanulate, glabrous, white, often yellowish near the base. Anthers never 

 twisted. Capsule \ in., subglobose, smooth, 2-celled, 2-4-valved, normally 4-seeded. 

 Seeds glabrous. By the prominent persistent bracts, this species is not likely to be 

 confounded with any other Ipom&a; but it has probably been passed for Parana 

 racemosa, which it somewhat resembles in its scandent habit and numerous white 

 flowers in lax cymes. 



34. I. cynanchifolia, Clarke; hairy, leaves ovate-lanceolate cordate 

 acuminate entire, peduncles 0, pedicels racemose or subfasciculate, bracts 

 caducous, sepals lanceolate elongate, corolla small rose, capsule glabrous. 

 Convolvulus cynanchifolius, Wall. Cat'. 1399. 



SIKKIM and BHOTAN ; alt. 2-5000 ft., frequent, Clarke. DISTRIB. Burma. 



Scandent, twining. Leaves 3 by 1^- in., more or less hairy; petiole 1-2. Pedicels 

 5- in., rigid, fascicled, or forming a raceme 1-2 in., recurved in fruit. Sepals ^ \ in., 

 hirsute, blackish green, widening in fruit. Corolla ^-f in., campanulate, glabrous, 

 with a dark spot at the base. Anthers never twisted. Ovary 2-celled, 4-ovuled ; 

 stigma small, of 2 subsessile globes. Capsule 5-5 in., subglobose, 2-celled, usually 

 4-seeded. Seeds glabrous. Eegarded by Choisy (in DC. Prodr. ix. 366) as identical 

 with /. criocarpa, from his never having seen Wallich's specimens. /. cynanchifolia 

 is very near /. calcina, Benth, but the sepals (even in fruit) are not cordate. 



35. I. Grlenieii, Thwaites in litt. ; glabrous, leaves subcordate elongate- 

 oblong entire, peduncles 1-fld. ebracteate, sepals ovate subacute, corolla middle- 

 sized subcampanulate. 



CEYLON ; Thwaites. 



Creeping, hardly twining. Leaves 2 by ^ in., shallowly cordate, gradually nar- 

 rowed from the very base to the apex, not acuminate, undulate ; petiole 1 in. 

 Peduncles -5 in. Sepals ^- in., obscurely muricate. Corolla f in., tube %~ in. 

 broad. Described from a fragment which flowered at Kew in 1871 ; it appears very 

 distinct.
