 in few localities, its decidedly greater prevalence in the 

 northern provinces may warrant its assignment to the Scot- 

 tish, rather than to the British type of distribution. A rare 

 plant of the Highland provinces, where its ascertained 

 western boundary would be marked by a line from Renfrew, 

 through Stirling, Perth, and Moray, into the East of Rossr 

 shire ; so that at present it seems quite unknown in the 

 West-Highland province, where its occurrence may still be 

 expected, however sparingly.
