duncles axillary, solitary, very short, or almost wanting, bear- 

 ing- many small, rose-coloured, sessile flowers, forming globu- 

 lar heads. Bractes or involucres many, linear, recurved. 

 Calyx, leaflets as long as the corol, hairy, tapering to a rather 

 long, recurved point. Corol having the border slightly mark- 

 ed with ten indentures. Anthers half hid in the tube of the 

 corol. Stif/ma of two round lobes. Capsule globular, villous, 

 size of a marrow-fat pea, two-celled, with two light-coloured 

 seeds in each. 



Obs. There is a variety of the above, if not a distinct spe- 

 cies, with white flowers, in round sessile heads, and having 

 narrower leaves ; in other respects they exactly agree ; both 

 are natives of Bengal and both are now growing luxuriantly in 

 the Botanic garden. Compare them with Ipomoea tamnijblia.
