Estimate of provinces 3. Estimate of counties 10. 



Latitude 56 — 59. Highland tj-pe of distribution. 



Ai'ctic region. Midarctic — Superarctic zones. 



Descends to 550 yards, in North Highlands. 



Ascends to 1400 yards, in East Highlands. 



Range of mean annual temperature 39 — 32. 



Native. Eupestral, Glareal. Frequent on the rocky 

 and gravelly summits of the Higliland mountains, de- 

 scending to 700 or 650 yards in the East Highlands, and 

 stni lower on Ben Hope in the North Highlands. It thus 

 passes slightly and rarely within the limits of the infer- 

 arctic zone. Professor Dickie thinks that he saw it, in a 

 baiTen state, at the very summit of Ben-na-muic-dhu, 

 nearly 50 yards higher than the altitude above given ; and 

 I found it rather above 1400 yards on the same hill 

 myself.

 highest parts of Ben Lawers," found by George Don, ac- 

 cording to Hooker's Flora Scotica. But this most un- 

 likely habitat ajipears to have been made only by an error
