SPHENOLOBUS 169 
the Lowlands. It is rare in the East Highlands, except in 
the granite districts of Aberdeen and Kincardine, and at 
the western boundary of this province. Is frequent on the 
granite and schistose rocks of the West Highlands. Is very 
rare in the Inner Hebrides, and has not been found in the 
Outer islands. Is rare in West Ross, and appears to be so 
throughout the North Highlands. It has not been found 
in Orkney or Shetland. ‘This species descends to sea-level 
in the West Highlands, but is uncommon below 800-1000 
ft. alt. It ascends to 3000 ft. alt. in Mid Perth, but is very 
rare at that altitude. It is most common between 1000 ft. 
and 2000 ft. alt., but one of its favourite localities is in old 
birch coppices, which are frequently seen near the foot of 
highland glens, at from 500-1000 ft. alt. In such places it 
is frequently common on the stems of the trees; also not 
rarely on isolated birch-trees on the hillside. Although 
occurring on such trees and more rarely on firs, the most 
general habitat of the species is on boulders and rocks in 
partial shade. Perianths are common, and fruit, which is 
mature from April to August and October, is frequent.
