Native. Sylvestral, Septal. This plant is found in 

 almost all the counties of the first 13 or 14 provmces. 

 In Scotland it becomes one of the rarer plants ; and I am 

 not yet aware of any locality northward of the Clyde and 

 Forth, in which its genuine nativity is free from doubt or 

 question. It occurs as far north as Moray, where it is 

 marked as doubtfully indigenous, by the Rev. George 

 Gordon. In the Flora of Aberdeen, it finds place only 

 as an introduced plant. In that of Forfar, it is given 

 as "naturalised in various places." There remain two 

 localities, "Inchmahone, in the Loch of Monteith," and 

 Cleish woods, both in the East Highland province, and 

 both being places to be suspected ; moreover, neither of 

 them resting on sufficient authority, when the question is 

 not one of nomenclature, but one of nativity.
