174 THE DISTRIBUTION OF HEPATIC IN SCOTLAND 
ANASTREPTA (Lindb.) Schiffn. 
ANASTREPTA ORCADENSIS (Hook.) Schiffn. 
Jung. orcadensis Hook. 
Generally distributed over the Highlands in the 
mountainous districts, with the exception of North Perth, 
where it is apparently absent, or at least very rare. It is 
very rare in the Lowlands and in Fife. Is rather common 
in the East Highlands, especially towards its western 
boundary, where it is sometimes quite common. It is 
common, and often very common, on the hills of the West 
Highlands, and is rather common in the North Highlands. 
It has not been found in Shetland or the Outer Hebrides, 
though it doubtless occurs on the hills of the latter district 
at least; but the want of suitable localities in the exposed 
islands must cause it to be rare. This species is most 
common on the hills from about 1500-2500 ft. alt., but it 
occasionally occurs in quantity in subalpine woods from 
800-1200 ft. alt. in the East Highlands, especially towards 
its western boundary, while it is rather common in several 
parts of the West Highlands from sea-level on moist shady 
banks and among long heather. It also sometimes is found 
among Sphagnum. When on the hills its usual localities 
are steep grassy banks, rock ledges, and stony ground 
among Myrtillus, etc. It ascends to 3200 ft. alt. in Mid 
Perth and to 3700 ft. alt. on Ben Nevis. It forms pale- 
green or reddish-brown erect tufts, and is very frequently 
in mixture, especially with Buzz. tricrenata, which it much 
resembles when growing. Perianths have not been seen ; 
male plants are uncommon. Gemme are common.
