North limit in Durham and Lancashire. 



Estimate of provinces 11. Estimate of counties 50. 



Latitude 50 — 55. English type of distribution. 



Agrarian region. Inferagraraian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperatiu-e 51 — 47. 



Native. Septal and Sylvestral. Very doubtfiil whether 

 this species is indigenous anjTvhere in Scotland. In the 

 Flora of Moray and Berwick, it is mentioned only as an in-

 locality of Stratheam, on the authority of Dr. Araott, in 

 the Flora Scotica. Frequent in the more southern pro- 

 vinces of England.
