Estimate of provinces 18. Estimate of counties 82. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagrarian — Inferarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 600 or 650 yards, in East Highlands. 



Range of mean annual temperature 51 — 41. 



Native. Sylvestral, &c. For reasons nearly similar to 

 those mentioned under the head of ' Rubus fruticosus,' I 

 find myself compelled to group a long series of forms (va-

Native. Septal, &c. Again I am compelled to give the 

 distribution of a group of the Sweet-briar Roses, which 

 many botanists name and describe as five or six species ; 

 and which, could this have been accomplished, I should
