Native. Glareal and Ericetal. Although generally 

 .spread through Britain, when we test its distribution by 

 provinces, it is apparently absent from so many counties, 

 that the census of 70 would seem too high under existing 

 knowledge ; and, indeed, only 45 counties can yet be 

 named for it on recorded authority, including my own 

 manuscript notes therewith. I have not met with examples 

 quite up to 600 yards, and therefore cite the highest limit 

 from Dr. Dickie, who fixes it at 2000 feet. As far as 

 British specimens are concerned, the "Rosa rubella" 

 would seem to represent a variety of Rosa spinosissima, 

 or to be simply a synonym of the latter.
