with Scapania gracilis (Beeby); Saxa Vord, Unst, with 
Blepharostoma trichophyllwm (Lillie). 
PLEUROCLADA Spruce 
PLEUROCLADA ALBESCENS (Hook.) Spruce 
This alpine species is confined to some of the higher 
mountains in the Highlands. It has been found in widely 
separated districts, but is too rare to admit of any special 
preference for either side of the country, though it appears 
to be rather more frequent towards the eastern side. It 
grows on moist soil where snow lingers through part of 
the summer, and has not been found below 3000 ft. alt. 
It reaches to about 4800 ft. alt. in Ben Nevis. 
The var. islandica is rarer than the typical plant, and is 
found at lower levels, descending to below 2000 ft. alt. in 
one locality.
