Native. Uliginal. Regarded as a plant refeiTed to the 

 British type of distribution, this species is very local in the 

 southern counties of England. In this respect, notwith- 

 standing its provincial generality, it inclines towards the 

 Scottish type. But it has probably been rendered artifi- 

 cially much scarcer in England thi'ough the progress of 

 enclosures and drainage of the wastes and bogs, where it 

 may have formerly grown. Perhaps it rises to the super- 

 arctic zone in the West Highlands ; attaining almost 900 

 yai'ds on the Nevis range, where the Calluna fails consi- 

 derably lower than that altitude.
