208 CI. OONVOLVULACB^. (C. B. Clarke.) [^Ipomcea . 



Annual, twining. Leaves 3 by 2 in. ; petiole 2 in. Pediincles J-lf in. ; braets 

 linear, deciduous ; pedicels |-1 in., racemose or subumbellate. Sepals | in., glabrous. 

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

 twisted. Ca/psvie \-^ in., ovoid, glabrous, 2-celled, 2-Talved, 4-2-seeded. Seeds 

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

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

 lected by Pallas. 



33. X. poranoides, Clarhe ; glabrous, leaves ovate-lanceolate cordate 

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

 persistent, sepals ovate obtuse unequal, corolla small white. 



SiKKiM and British Bhotan ; alt. 3-5000 ft., frequent, Clarke. 



Scandent, twining. Leaves 3 by 2 in. ; petiole li in. Fedimdes 1-3 in. ; bracts 

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

 5 in., subcampanulate, glabrous, white, often yellowish near the base. Anthers never 

 twisted. Capsule J in., subglobose, smooth, 2-ceIled, 2-4-valved, normally 4-6eeded. 

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

 confounded with any other Ipomisa ; but it has probably been passed for Pora/na 

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

 flowers in lax cymes. 



34. X. cynanclxifolia, Clarhe; 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, Wcdl. Cat. 1399. 



StKKiM and Bhotah ; alt. 2-5000 ft., frequent, Clarke. — Distkib. Burma. 



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

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

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

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

 stigma small, of 2 subsessile globes. Capside \-^ in., subglobose, 2-celled, usually 

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

 with /. eriocarpa, from his never having seen WaUich's specimens. 7. cynanohifoUd 

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



35. X. G-Ienieii, 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 J in., shallowly cordate, gradually nar- 

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

 Peduncles J-J in. Sepals |— J in., obscurely muricate. Corolla f in., tube ^— J in. 

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

 distinct. 



36. X. denticulata, Choig. in DC. Prodr. ix. 379, not of B. Br.; 



glabrous, leaves ovate-cordate acute entire denticulate angular or somewhat 

 lobed, peduncles short 1-3-fld., pedicels long, sepals elliptic suddenly acute, 

 corolla IJ in. purple. Benth. Fl. Austral, iv. 421. I. subdentata, Miq. Fl.
