198 53. SCROPHULARIACEiE. 



Latitude 56 — 59. Highland type of distribution. 



Arctic region. Midarctic zone. 



Descends to 750 yards, in East Highlands. 



Ascends to 900 yards, in same province. 



Range of mean annual temperature 39 — 37. 



Native. Rupestral. The five counties above named are 

 all which are supposed to produce this species ; and al- 

 though none of them can be considered improbable, the 

 records are liable to distrust from uncertainty. The plant 

 is well known to occur in different places in Perth and For- 

 far, and I have collected specimens in both these counties. 

 Ai-gyle and West- Inverness were pubUshed for " V. fruti- 

 culosa ;" but in all likelihood it was the discovery of the 

 present species which led to the reports of V. fruticulosa 

 growing in those two western counties. I am not aware on 

 what personal authority V. saxatilis is repoited in Ander- 

 son's Guide as found on Ben More, in Assynt, Sutherland ; 

 but that habitat vrould seem not at all improbable in itself. 



Veronica, fruticulosa, Linn. 



Area (14) [15 16]. 



Incognit ; Alien. Mr. R. Brown was supposed to have 

 collected this species on Ben Lawers, in Perthshire, where 

 only the very similar V. saxatilis can now be found. The 

 Rev. Dr. Walker was confidently reported to have disco- 

 vered it on Ben Cruachan, in Argyleshire, and to have 

 thence introduced the species into his own garden. Never- 

 theless, I must deem that the true V. fruticulosa never was 

 collected on the Highland mountains. Mr. H. M. Balfour 

 informs me that it has become established on a wall near 

 Edinburgh.
