Latitude 50 — 58. British type of distribution. 



A. A. regions. Inferagrariau — Inferarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 700 or 750 yards, in the East Highlands. 



Range of mean annual temperature 52 — 40. 



Native. Ericetal. Though frequent in Britain, this is 

 considerably less so than the Ulex europaeus or Spartium 

 Scoparium ; while it ascends higher than those allied 

 shrubs, on the northern mountains. I observed it on the 

 moors of Aberdeenshire, as high as 2000 feet in several 

 places ; the highest spot marked for it in my note-book, 

 being 2200 feet, on the hills near Castletown.

Native. Glareal. Here again I feel at a loss whether 

 to estimate the county census at 80, or at 75. The apparent 

 absence of the species from the North Isles, would bring 

 the estimate down to 79; those three groups being reckoned 

 as three counties. But if it grows in all the counties of the 

 main land, the estimate would still be nearer to 80 than to 

 75. Were not the earlier pages of the volume printed oflF, 

 before this remark is penned, I should be now tempted to 

 introduce a middle estimate, of 78, between those two
