LOPHOCOLEA Dum. 
LOPHOCOLEA BIDENTATA (L.) Dui. 
Generally distributed from Dumfries to Shetland. This 
species and L. cuspidata are found in much greater 
quantity in the Lowlands than in the Highlands; they are 
the only generally distributed species of which this can be 
said, with the possible exception of Conocephalum conicwm. 
The present plant usually occurs in a sterile state, and 
frequently only as scattered stems among mosses. As it 
cannot usually be distinguished with certainty from JL. 
cuspidata in the absence of inflorescence, its distribution is 
less accurately known than in the latter species. It is, how- 
ever, common on walls, etc., in the region of cultivation in 
the Lowlands, and is frequent in the lower subalpine 
region. It is common in the low-lying parts of the East 
Highlands, and is rather common, but much less so, in the 
West Highlands. It appears to be frequent in the North 
Highlands, and less so in Orkney and Shetland. This 
species is uncommon on the Southern Uplands, where it 
ascends to 2100 ft. alt. It is rare on the hills in the 
Highlands, and has not been found above 2000 ft. alt. 
It frequently forms large tufts on walls in the Lowlands 
and part of the East Highlands, but usually occurs only as 
thin patches or scattered stems in the West and North 
Highlands. Perianths are rare, and fruit, which matures 
in April and May, is very rare.
