 style about as long as the nut, stigmas 3, very long, capillary. 



Moist region ; in wet places up to 3000 ft. ; rather common. Fl.

Very abundant in the Mahaweli River in Dumbara, where it is largely

I follow Trimen in regarding this as distinct from Roxburgh's C. 

 tegetum, though failing to find any valid characters by which to sepa- 

 rate it.
