SCAPANIA PURPURASCENS (Hook.) Tayl. 
Generally distributed from Dumfries to Shetland, and 
common except in the low-lying districts of the Lowlands 
and the agricultural region of the East Highlands. In the 
West Lowlands it is frequent, and it is locally common in 
subalpine districts. In the East Lowlands it is uncommon 
in the low ground, frequent in some subalpine districts, and 
common in the Upper Tweed valley. It is frequent in 
Fife and the low ground of the East Highlands, and is 
common oyer all the hilly districts of the Highland pro- 
vinces and on the islands, being one of the commonest 
species by the sides of streams and on wet rocks. The 
most frequent form in the Lowlands, and also frequent over 
the Highlands, is the var. ambigua De Not, an intermediate 
plant between the type and S. wndulata, and which in 
many cases might be placed equally to one or the other. 
The var. speciosa Nees is not rare. S. purpwrascens forms 
small tufts on wet rocks, most often by the side of streams, 
or covers considerable spaces on wet rocks and rocky banks
