Native. Ericetal, Sylvestral. A rare plant in the pro- 

 vince of Ouse, and counties adjacent thereto; and yet from 

 its abundance on the mountains and moors, and in many 

 woods, it may properly be pronounced a very common 

 British species, although becoming scarce in the east or 

 south-east of England. It endures the exposure of the 

 higher mountain summits, above 1000 or 1200 yards, better 

 than any other shrub except the Salix herbacea ; though 

 usually it is very dwarf and depressed in such situations.
