266 18. GERANIACE,«. 



Descends to the coast level, in the Peninsula. 



Ascends to 200 yards, in the Lake province. 



Range of mean annual temperature 51 — 46. 



Native. Rupestral and Viatical. Excepting Lowe's list 

 of Orkney plants, I am not aware of any recorded authority 

 for the occurrence of this species more northward than the 

 county of Ross. It may be that 60 counties would have 

 been a nearer estimate ; though, if called on to specify 

 those from which it is probably quite absent, I should have 

 difficulty in selecting the dozen which have been deducted 

 fiom the whole number, in the estimate given above. Ac- 

 cording to the ' London Catalogue ' it is mentioned in four- 

 fifths of the local Floras. 



239. Geranium Robertianum, Linn. 

 239,b. Geranium purpureum, Forst. 



Area, general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Orkney and Sutherland. 



Estimate of provinces 18. Estimate of counties 81. 



Latitude 50 — 60. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 500 or 550 yards, in the East Highlands. 



Range of mean annual temperature 52 — 41. 



Native. Viatical and Rupestral. Almost equally abun- 

 dant as G. molle, in the two lower agrarian zones ; and 

 probably less rare than the latter in the upper agrarian 

 zone. As it is not recorded by Mr. Edmondston, I do not 

 venture to include Shetland in the county estimate ; and 

 yet its occun-ence up to the extreme limit of the agrarian 

 region, in the East Highland province, might justify the
