A large climber : leaves 3|-6 in. by 2-4 in., petioles 1-3 in. ; peduncles 2-6 in. 

 with small deciduous linear bracts at origin of pedicels, whicb are from 1-2 in, long. 

 Sepals f in., refiexed but not enlarging in fruit. Corolla white, 2| in. long, mouth 

 2 in. across. Capsule | in diam. 



This is a very distinct species, much nearer to I. petaloidea (with which it 

 agrees in having thickened pedicels and of which it has exactly the calyx) than to 

 I. cymosa. It is however easily distinguished from I. petaloidea by its leaves, which 

 are quite like those of I. cymosa, and by its glabrous corolla. 



49. Ipomoea carnora Br.

Pahang : Ridley ! 



56 b. Ipomoea gracillima Prain ; glabrous, leaves pedately lobed, 

 lobes narrow, spathulate sub-sinuate, peduncles 1-7 fld., filiform 

 elongated, sepals ovate obtuse, corolla small purple, seeds velvety with 

 a few long hairs at tip. I palmata var ? gracillima. Coll. 8f Hemsl., 

 Journ. Linn. Soc, xxviii., 97. 



Upper Burma : Meiktila, Collett ! 



A slender climber ; leaves 1-2 in. diam. petioles 1 in. ; peduncles much larger 

 than leaves (2-4 in.) ; sepals ^ in., corolla |-| in ; capsule f in. 



Yery closely resembles I. palmata in appearance but is easily distinguished by 

 its much longer peduncles, its flowers less than half the size, and its very different 

 seeds.

Lepistemon Wallichii (Convolvulus cephalanthus Wall. Cat. n. 1402 ; Ipomoea 

 Wallichii Steud.) scarcely diifers from Lepistemon flavescens (Ipomoea flavescens 

 Steud.) as has been already pointed out by Choisy {DO. Prodr. ix, 34S.) Choisy, 

 however, has not seen his way to formally uniting the two plants even when 

 monographing the natural order ; on this account, and also because the geographi- 

 cal areas of the two forms did not then seem to overlap, Mr. Clarke has kept up the 

 distinctive name and position of the Indian one ; he has however, pointed out how 

 closely they are related, and how nearly both are allied to still another form from
