238 THE DISTRIBUTION OF HEPATICZ IN SCOTLAND 
LEPIDOZIA REPTANS (L.) Dum. 
This species, though one of the most generally distri- 
buted from Dumfries to Shetland, is rare or absent in 
several districts. It is uncommon in the low-lying parts of 
the West Lowlands, and has not been observed on the 
lower ground on the Tinto and Elvanfoot or Leadhills 
districts of the Upper Clyde valley, but it is frequent 
in some of the other subalpine districts, and ascends to 
1900 ft. alt. Its distribution seems greatly dependent on 
the presence of peat or decaying vegetable matter. It is 
also uncommon in several parts of the East Lowlands, 
especially in the Upper Tweed valley. It is frequent 
throughout the East Highlands, except near the coast, 
and is common in the West Highlands, but is rather un- 
common on the less sheltered Hebrides. Is common in 
West Ross, and frequent throughout the North Highlands. 
It appears to be uncommon in Orkney and Shetland, 
though found in several parts of the latter. The species 
is rare on the hills, though it has been found to 3200 ft. alt. 
in Mid Perth. In the West Highlands it has not been 
found above 1000 ft. alt. 
Grows in thin green layers, more rarely in compact 
cushions, and frequently creeping as scattered stems 
among other species, on banks, stumps, about the roots 
of trees, and occasionally on tree stems. Perianths are 
frequent; and fruit, mature from April to August, is 
not rare.
