HARPALEJEUNEA 315 
the side of low-lying inland lochs. In some parts of the 
coast of West Inverness it is rather common, though less 
so than Harpalejeunea ovata. ‘This species is only found 
in well-sheltered places, and is therefore rare in the Hebrides. 
It appears to be absent in the extreme north, though it 
may probably be found on the west coast of Sutherland. 
The localities given in books for this species in the East 
Highlands should be transferred to Cololejewnea calearea. 
It grows on rocks and trees—birch, hazel, oak, and ash— 
in ravines and moist woods, most commonly in schistose 
districts, but is also found on gneiss, granite, and basalt. 
It is frequently associated with Harpalejewnea ovata, and 
more rarely forms unmixed patches than that species does, 
especially when on trees. On rocks it is sometimes seen 
as closely applied scattered stems. Female bracts are 
frequent, but perianths very rare; male bracts are common, 
though well-developed antheridia are uncommon. Fruit 
has not been observed.
