SACCOGYNA 201 
found to the east of these districts. It is very common 
over all the West Highlands and in the Inner and Outer 
Hebrides; also common in West Ross and probably on the 
west coast of Sutherland. It is rare on the north coast, 
and has not been found to the east of Tongue. It 
approaches the east coast in Ross-shire, but has not been 
found in the east of Sutherland or in Caithness. It has 
been found in several places in Orkney and Shetland, 
where it appears to be rather common. There are other 
instances of Atlantic species being found in these islands 
though apparently absent from the well-searched Caithness. 
This species is confined to the low ground, and grows 
in large, spreading, pale-green or yellowish patches on wet 
rocks, also creeping over mosses on moist banks, and some- 
times erect in moss tufts. In the West Highlands and 
islands it is found in exposed as well as shady places, but 
when at any distance from the coast it only occurs in very 
sheltered ground, and chiefly in ravines. Sterile female 
inflorescence is frequent; no male inflorescence or fruit 
has been seen by the author in Scotland.
