It has been stated by several authors that 2. syloestris ¢ is a plant 
of Northern Europe, and R. Friesii of the South. It would be 
perhaps more correct ‘to say that the two varieties have Baste ern and 
Western proclivities gee in Europe, but nesitver are these

The locality is not beyond a suspicion of introduction, but it is prob-

other places, though likely to be a scarce plant in this country. From 
abroad there are specimens of /. sylvestris in the herbarium of the 
British Museum from Thuringia, Wallroth; Denmark, Trimen ;
