Native. Viatical. Distrusted in its few Scottish locali- 

 ties, and consequently the nos. which indicate the pro- 

 vinces of Scotland are enclosed in the line devoted to the 

 area of this species. The Edinburgh Society's Catalogue 

 includes it with the doubtfully native plants of the Forth 

 district. Dr. Johnston considers it introduced at Berwick- 

 on-Tweed. And in reporting a locality in Wigtonshire, 

 Professor R. Graham wrote, " This is a scarce plant in 

 Scotland, and it may be doubted whether it is ever met 

 with there, except when it has been introduced." Still, it 

 is by no means a very unlikely plant to be truly indigenous 

 in the West Lowland province.
