CEPHALOZIA 203 
Islands up to Shetland, and ascends to 3800 ft. alt. on Ben 
Nevis, and to at least 3500 ft. alt. in Mid Perth. It 
becomes, however, less frequent towards the higher parts of 
the hills. I have seen some hundreds of specimens, and 
from all the counties, so that its special distribution is not 
given. 
This species grows in any moist position and on all our 
geological formations. It is one of the common plants of 
peat-mosses, and occurs frequently also on stumps and 
decaying logs. Fruit is usually present in spring, except 
in very wet ground. It is mature from February to June 
and July. Gemme are rare. 
CEPHALOZIA LAMMERSIANA (LHiiben.) Spruce 
Widely distributed from Dumfries to Shetland, but 
uncommon. It is rare in the Lowlands and in at least some 
parts of both East and West Highlands, but its distribution 
apart from C. bicuspidata is imperfectly known. The 
author has found it to be uncommon in most of the districts 
which he has examined, though on the other hand in the 
most minutely searched district of Moidart he has found it 
to be frequent. Comparatively few specimens of the plant 
have been sent him from the various parts of Scotland, and 
the probability is that the plant is generally uncommon if 
not rare. 
It prefers wetter ground than C. bicuspidata, and is 
usually found at the side of ditches and runnels, in marshy 
ground, and the wetter parts of peat-mosses. It nearly 
always grows unmixed. Though usually on the low ground, 
it ascends a considerable distance up the hills, but rarely 
above 2000 ft. alt. It occurs on a wet rock on Ben Nevis 
at 3600 ft. alt. Perianths are common, but fruit is rather 
uncommon.
