This fine species appears to attain its fullest development on the
Grampian range ; although it is found in Scandinavia, and on the higher
peaks of the Pyrenees, Switzerland, the Tyrol, and eastward to Salzburg and
Carinthia, we have not seen any specimens to equal those of native growth.

H a b .— With the typical form on Ben Nevis and Ben Macdhui (Hooker) ! !
This form is described as the type by Zetterstedt, because as he says,
it is the common form in Scandinavia and assumed to be therefore more
typical. There does not seem any reason to disturb Hooker’s original
arrangement, although it is certain the variety more frequently bears fruit,
while the type is richer in male inflorescence.
