Descends to 500 yards, in the East Highlands. 



Ascends to 1400 yards, in the same province (G. Dickie). 



Range of mean annual temperature 41 — 33. 



Native. Rupestral and Pascual. Frequent on the 

 Highland mountains ; and constituting, in some places, a 

 considerable portion of the gieen sward ; like the Bellis or 

 Prunella in our dry pastures of England. In Shetland, it 

 must be below 500 yards. It is worthy of note, that this 

 plant, which can flourish below 600 yai'ds, on the Grampian 

 mountains, should not occur at all on those of Wales or 

 England. It is, however, only among lofty hills that the 

 plant grows at its lower elevations, with the exception of 

 Shetland, where the summer temperature is doubtless low, 

 with reference to the mean of the year, which is made so 

 high as 48° of Fahrenheit, by recent observations taken 

 hourly.
