SCAPANIA 263 
to the low ground, hardly ascending above 1000 ft. alt. 
Forms compact light-brown patches, sometimes of consider- 
able extent when on rocks, on banks, on old walls, rocks 
and boulders, and sometimes in gravelly detritus at the 
side of streams in similar situations to S. subalpina. It 
prefers moist and rather shaded localities, and is frequently 
close to the sea-shore when in the West Highlands. It has 
been found on schistose, gneissic, and basaltic rocks, but not 
on limestone. Fruit is common from March to July, and 
also is found in late autumn. Gemme are common.
