162 46. PYROLACE^-. 



Range of mean annual temperature 47 — 40. 



Native. Sylvestral, Rupestral. A local species. I have 

 seen it in Cumberland, Perth, Forfar, Aberdeen. The Rev. 

 G. Gordon reports it from Banff, Moray, Ross. On old 

 authority it was recorded in Argyle, Dumfries, Northum- 

 berland, York ; and the two latter have been confirmed by 

 Dr. Johnston, who is said to have found the species on 

 Yevering Bell, one of the Cheviot hills, and by the Rev. 

 George Finder, who lately discovered it near Sedbergh. 

 It is recorded also for Sussex, in the New Botanist's Guide, 

 on such good authority as that of Mr. Borrer; but the 

 county itself appears so unlikely, for a species otherwise 

 quite boreal and montane, that I hesitate to rely upon the 

 record. I think it rises to a higher elevation than above 

 indicated, and probably into the midarctic zone.

Native. Sylvestral. A very scarce plant in Scotland ; 

 recorded from the seven counties tibove named. Its occur- 

 rence in Forfarshire is recorded solely by G. Don, who 

 indicates the vague and probably false habitat of " sum- 

 mits of the Clova Mountains." Mr. Borrer recorded it
