Ipomoea. pentandria monogyxia. 501 



Stigma three-Iobed ; lobes round. Capsules smooth, three- 

 celled, with two smooth, black seeds in each. 



Obs. This, and I. ccerulea (probably I. hederacea of Jac- 

 quin,) are exactly the same in the inflorescence, germ, stigma 

 and capsules ; but they differ specifically. This being- peren- 

 nial, and having the leaves constantly without any tendency 

 to be lobate, whereas that is annual, with three-lobed leaves. 

 I may farther add, that plants raised from seed received from 

 the Honourable Charles Greville, in London, under the name 

 Convolvulus hederaceus, differ only in the colour of the flow- 

 ers from my I. camlea,'u\ which it is blue, and in this, heder- 

 acea, white. 



7. I. ccerulea. K6n. Mss. 



Annual, twining, hairy. Leaves cordate, three-lobed, 

 downy. Peduncles from two to three-flowered, margins of the 

 corol sub-entire. Stigmas three-lobed. Capsules three- celled. 



Beng. Neel-kwlim. 



It is common during- the rains inmost parts of India. 



Stems and branches twining-, annual, round, hairy, from six 

 to twelve feet long, as thick as a crow's quill. Leaves alter- 

 nate, petioled, broad-cordate, three-lobed, downy ; from two 

 to four inches long, acute, &c. almost as in Dillenius's figures 

 of Convolvulus Nil. Peduncles axillary, length of the peti- 

 oles, round, hairy, from two to three-flowered. Bractes and 

 leaflets of the calyx linear. Flowers large, of a beautiful 

 light, but bright blue. Stigma sub-globular, large, glandu- 

 lar, three-lobed. Capsule much shorter than the calyx, smooth, 

 three-celled, with two seeds in each. 



I have often reared this species in my garden, on account 

 of the great beauty of its large flowers, and do not find it to 

 vary. 



The seeds of this plant are sold in the native apothecaries' 

 shops in Calcutta, under the name Kala dana, and used as a 

 purgative. I have heard them much praised as an effectual, 

 quick-operating, safe cathartic. The dose is from thirty to
