bulbil condition). Thirdly, I have got Air. C. Fitch to make a draw- 

 ing, herewith appended, of the stolons, bulbils and culm base 



from the ample Kew material. My old pictures in the ' Linnean 

 Journal,' v. 21, t. 2, figs. 17, 18, are entirely diagrammatic ; t. 18, 

 seen by comparing with Mr. Fitch's figure, shews the common state 

 of C. Jeminicus ; t. 17 represents perhaps rather G. usitatus 

 Burchell ; but I observe that a specimen in this herbarium from 

 Uganda (said to be C. vestitus Hochst. in ' Flora,' 1845, p. 755), 

 which I formerly referred to G. Jeminicus, is perhaps G. usitatus 

 Burchell. Except in the delicacy of the stolons, I still do not quite 

 understand how C. Jeminicus differs in its manner of growth from 

 some of its neighbours.
