72 1 RANUNCULACEiE. 



Estimate of provinces 17. Estimate of comities 50. 



Latitude 50 — 59. Scottish type of distribution. 



A. A. regions. Inferagrarian — Inferarctic zones. 



Descends to the coast level (?), in the Peninsula. 



Ascends to 650 yards, in the Lake province. 



Range of mean annual temperatm'e 52 — 41. 



Native. Rupestral. In the Peninsula, Thames and 

 Severn, extremely local. In Ouse, several localities are 

 recorded ; and as it occm's also on the coasts of South 

 Wales, the type of distribution shows some tendency to be- 

 come British, rather than the Scottish. Its chief prevalence 

 is from North Wales to the East Higlilands ; only few lo- 

 calities being known in the two most northerly provinces. 

 In none of the provinces can it be deemed a common spe- 

 cies. Though foimd also in many places inland, on or 

 among hills, this species seems to have some considerable 

 tendency to the sea coast.
