304 THE DISTRIBUTION OF HEPATIC IN SCOTLAND 
COLUROLEJEUNEA (Spruce) Schiffn. 
COLUROLEJEUNEA CALYPTRIFOLIA (Hook.) Schiffn. 
One of the rarer species of the Lejewnew group, and 
almost confined to moist, sheltered ravines on the west 
coast of the Highlands. It also, though more rarely, occurs 
a few miles from the coast in ravines at the side of inland 
lochs which are only slightly above sea-level, as in the case 
of Loch Lomond. Like most of our Lejewnew, it is a small 
species, and lable to be overlooked by those unfamiliar with 
the appearance of this group in the field; but it is without 
doubt rare, and is often absent from ravines which seem 
favourable for its requirements. It has been found from 
Arran to Skye and West Ross, but only in small quantity. 
Though nearly always occurring on wet rocks in very 
sheltered ground, it has also been found on conifers, but not 
on deciduous trees. This species commonly grows un- 
mixed in very small lght-green patches directly on the 
rock, but is occasionally found on Frullania Tamarisei 
and Radula aquilegia, accompanied by other small 
Lejeunee. Perianths are usually present, but fruit, mature 
April to June, appears to be rare. It has been found on 
schistose, gneissic, and granite rocks.
