GYMNOMITRIUM CONCINNATUM (Lightf.) Corda 
Very rare in the Lowlands, having been found only in 
small quantity on the Kells range of hills in Kirkcudbright, 
where it descends to 1500 ft. alt. and at the head of 
Moftatdale. It has not been found in the East Lowlands, 
but, occurring as it does on the Moffat side of the boundary 
range between the Solway watershed and that of the 
Tweed, it is to be expected that it also will be found on the 
latter. It is common on the higher hills over all the 
Highlands, descending to 1300 ft. alt. in the eastern district 
and to 1100 ft. in the western, and to nearly sea-level in 
Unst, Shetland. It ascends to the summit of Ben Nevis 
at 4400 ft. alt. It has not been found in the Inner 
Hebrides, as the higher hills, at least all those examined, 
are practically devoid of vegetation towards their summits. 
In the Outer Hebrides, it has only been found near the 
summit of one of the highest hills. It grows in compact 
brownish-yellow to white patches on soil and rocks. When 
at a considerable altitude it usually is found on the former, 
and occasionally even at rather low elevation. Fruit is 
common from June to August, but large sterile patches 
are frequently to be seen. 
Upon the rocks on the Highland mountains, frequent 
(Lightf. cf. Fl. Scot., p. 786).
