346 Dr. Greville's Account of a Collection of 



This fine Bri/um, which I have named after a naturalist daily 

 rising in public estimation (Mr. David Don, Librarian to the 

 Society), has at first sight the aspect of short specimens of 

 B. ventricosum, especially in the character of its fruit ; but the 

 much broader leaves, the very thickened margin, cxcurrent 

 nerve, and quite different kind of innovationary branches, are 

 abundant marks of distinction. I am not aware of any other 

 species with which it is likely to be confounded.
