country. It is frequent on the hills, and ascends to 3200 ft. 
‘in Mid Perth and to at least 2500 ft. alt. in the West 
Highlands. It is found on all formations. It is equally 
common on trees and rocks in the moist and sheltered parts 
of the Highlands, but in the drier and exposed districts 
it is mostly confined to rocks. This species is commonly 
sterile, but perianths are frequent, and fruit is not rare 
when on trees, being usually mature in August and 
September, but extending from June to October. 
The var. cornwhica is confined to rocks near the shore of 
the Atlantic coast. The var. robusta, at least when well 
marked, is also confined to the west side of the country, and 
usually to rocks near the shore,
