 being found in the provinces of the Peninsula and Severn 

 (neighbourhood of Bristol ; IMr. Thwaites), and also in 

 that of IVEersey, there would seem a presumption in favom' 

 of its occurrence on the coast both of South and of North 

 Wales. The county of Forfar is supported by two wit- 

 nesses for different localities, George Don and JMr. A. 

 Kerr ; and were it not so far beyond the northern limit of 

 the species in Britain, as otherwise known, that county 

 might have passed here unchallenged. The want of good 

 local Floras for Scotland, planned and written under any 

 views of science higher than those entertained by the 

 mere botanical collector, is a great inconvenience to the 

 botanical geographer. Between Northumberland and 

 Moray, we have only Floras and Catalogues indited for the
