1 RANUNCDLACEiE. 87 



1500 feet ; but have no certain recollection of seeing it 

 equally high elsewhere. That altitude raises it almost into 

 the arctic region, so that there seems no cHmatic cause to 

 prevent its occun-ence in the West and North Highlands. 



19. Ranunculus acris, Linn. 



Area, general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Shetland, Orkney, Hebrides. 



Estimate of provinces 18. Estimate of counties 82. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagi-aiian — Superarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 1300 yards, in the East Highlands.

Native. Pascual. Truly one of the most universally 

 distributed among om* native species ; ranging from the ex- 

 treme south to the extreme north, from the coast to the 

 summits of nearly the highest hills. I obseiTed it at 1200 

 yards, or upwards, on the Nevis range, and almost to the 

 summit of Ben Lawers, which is near 4000 feet in height.
