TRICHOCOLEA 259 
in one locality in wet ground on a hillside. It has not 
been found in any of the numerous sheltered glens of that 
province. Is very rare in Fife, and rare near the coast of 
the East Highlands, but becoming frequent in some 
sheltered ravines further inland. In the West Highlands 
it is a frequent species and sometimes common. Is rare in 
the Inner Hebrides, and has not been found in the Outer 
islands. Is rare in the North Highlands, and especially in 
the extreme north. Its distribution in Scotland appears 
rather to follow that of the rainfall than any particular 
preference towards the west side of the country. It is 
quite a frequent species in some of the wetter parts of the 
centre of the country where there is shelter. Its absence 
in the more rainy districts of the East Lowlands may be 
owing to this absence of sheltered ground. Although it 
occasionally is found in marshy ground which is exposed, 
it is most at home on the moist or wet banks of a sheltered 
ravine. It is a low-ground species, though it has been 
found up to 1200 ft. alt.in Mid Perth. Its preference for 
subalpine districts in the Lowlands is doubtless due to the 
agricultural region having too small a rainfall. 
Forms large light-green or cream-coloured cushions, 
frequently 2-3 feet in diameter. Fruit has not been seen.
