Descends to about 200 yards, in the North Highlands. 



Ascends to 1100 yards, in the East Highlands. 



Range of mean annual temperature 43 — 36. 



Native. Uliginal. Seldom so low as the agi-arian re- 

 gion ; but reported by Dr. Dickie, at 1000 feet in Aber- 

 deenshire ; and the name occurs in my note-book among 

 those of plants seen between 350 and 970 feet in Suther- 

 land. The locahty of " Cleghorn and Boniton woods," in 

 Lanarkshire, may be the lowest in respect of climate, if not 

 in respect of absolute elevation also ; and that locality 

 might probably waiTant an additional degi'ee or two above 

 the assigned temperature of 43. It is worthy of note that 

 this arctic species should hitherto not have been observed 

 in the North Isles.
