Generally distributed from Dumfries to Shetland, but 
uncommon m some districts. It is uncommon over the 
greater part of the West Lowlands, and is rather rare in 
the East Lowlands. Is rather common over the Highlands 
generally, though rare locally. A large number of speci- 
mens were examined when this plant and C. trivialis were 
mostly treated as the aggregate C. divauricata (Sm.), so 
that comparatively few localities are given for the segre- 
gates; but since then it is evident that the present species 
is much the commoner of the two, and it is no doubt 
considerably more common than the number of localities 
given would suggest. The East Lowlands and part of the 
West Lowlands must be excepted, as it is certainly uncom- 
mon in these districts. It also seems to be uncommon in 
the Hebrides, being undoubtedly so in those parts of Mull 
and Skye which have been examined. Although it is 
rather common in West Inverness, it is probably more 
common in Mid Perth and the East Highlands in general. 
It is uncommon on the hills, but ascends to 3900 ft. alt. in 
Mid Perth. This species is found on dry banks, sides of 
drains, and damp peaty banks, sometimes on boulders, old 
walls, and rocks, and creeping over Krull. Tamarisci. It 
forms nearly black thin layers in dry situations, though 
green in moist places. Plants are most commonly sterile, 
though perianths are rather common. Fruit, which is 
mature from July to October, is uncommon. Gemmee are
