GYMNOMITRIUM ALPINUM ((ottsche) Schifin. 
Sarc. alpinus Gottsche 
A rare species, but frequent in the granite districts, 
especially on the west side of the country, and on some of 
these hills it is rather common. It occurs also on porphy- 
ritic and schistose rocks, though much less frequently, and 
rarely in any quantity. In the West Lowlands it descends 
to about 1200 ft. alt., and to sea-level in one locality in the 
West Highlands, but is rarely seen below 1400 ft. alt. It 
ascends to 3500 ft. alt. in the East Highlands and to 4300 
ft. on Ben Nevis, but is seldom seen above 2500 ft. alt. on 
the western side of the country. 
It grows in compact, or more generally loose, tufts of a 
dark-brown colour on rather dry rocks and boulders. Male 
and female plants are common, both sometimes occurring 
in the same tuft, but fruit has not been found. 
Carrington’s Nardia Funckii var. robustior, described in 
his Brit. Hep., p. 19, is Gymn. alpinum, as Sim’s specimen 
shows; but it is probably also in part Mars. sparsifolia 
and M. Sullivanti, both of which Sim also collected at the 
same time, and which are also labelled Nardia Funckii in 
his Herbarium.
