RADULA Pasi 
the exposed islands. In most districts this species is only 
found on wet rocks in very sheltered ravines, but in West 
Inverness it is also found on trees in similar places. It is 
also not rare in that district on wet rocks on the shore, 
just above tide-mark. It grows in large reddish-brown 
patches without mixture as a rule, though frequently the 
small Lejewnece are to be seen creeping over it. When on 
trees it is of a lighter colour, and is then often in mixture 
with mosses. Perianths are rather rare when the plant is 
on rocks, but they are common when it is on trees, and 
fruit is also then frequent. The months in which mature 
fruit has been found are May, August, and November.
