Native. Agrestal. The estimate of 60 counties may be 

 rather too high ; that of 50 would likely be too low. The 

 provincial estimate includes the West Lowland province, 

 for which I am not aware of any positive authority. Nei- 

 ther have I any authority for this species in the Lake pro- 

 vince, except through the union of the Isle of Man to that 

 province. Said by Gardiner, in his Flora of Forfarshire, 

 to be frequent in that county ; and the Edinburgh bota- 

 nists attach the sign of frequency to the name in their 

 Catalogue. Rare about Berwick. Omitted from the 

 Floras of Glasgow, Aberdeen, Moray, and others more 

 northerly than these three ; as also from all my own local 

 lists of species observed in the Highland provinces.
