Jung. Muelleri Nees 
Widely distributed from Dumfries to Shetland, but 
generally uncommon. Is rare in both East and West 
Lowlands, Fife, and in the low-lying districts near the 
coast in the East Highlands. Is rather common in Central 
Scotland on the mountainous districts of Perth. Is fre- 
quent in some parts of the West and North Highlands. Is 
also frequent in parts of the Inner Hebrides, but has not 
yet been found in the Outer islands. It is rare in Orkney 
and Shetland. The part of Scotland where it is in greatest 
quantity is on the mountains of Mid Perth, where it ascends 
to 3400 ft. alt. It has not been found on any of the hills 
of the West Highlands, being confined to ravines and wet 
rocky banks on the low ground. Perhaps this may be due 
to its preference for soils which contain lime, as the hills 
on the west coast are mostly devoid of this. This species 
is rarely seen below 1000 ft. alt. in the Lowlands, but, as in 
the case of some other subalpine species, it is also found on 
moist ground in sand-dunes on the shore. 
It grows usually in rather large tufts, sometimes in large 
spreading masses, of generally a pale-green colour, among 
wet rocks, rock ledges, and sides of streams, especially of 
ravines. Sterile perianths are usually present; male plants 
are also common ; fruit is uncommon except on the hills.
