RaADULA COMPLANATA (L.) Dum. 
Generally distributed on the mainland and the more 
sheltered islands, being frequent in most counties and 
common in some. It is rather uncommon in the agricultural 
regions of the Lowlands, and rare in the subalpine region, but 
it is present in most shady glens and moist deciduous woods. 
In woods on drier ground and on isolated trees in exposed 
ground it is absent or very rare. This applies also to Fife 
and to the regions of small rainfall in the East Highlands. 
In the more central and wetter districts of the province it 
is common in the low-lying districts. Throughout the low 
parts of the West Highlands it is generally common, 
and it is frequent in the sheltered parts of the Inner 
Hebrides. In the exposed Outer Hebrides it is rare. It 
becomes less common in the North Highlands, is rare in 
Orkney, and has not been found in Shetland. As its 
principal habitat is on trees, it is generally only to be found
