ORDER ERICACEAE. 



690. Erica Tetralix, L. (Cross-leaved Heath). Native. 

 British type. Range 1-2. Common on the damper moors ; 

 ascending from the shore-level at Meathop and Foulshaw as 

 high up as Pteris, but, like E. cinerea, falling far short of the 

 Calluna. The highest place where I have noted it is 500 

 yards over Gatescarth Pass. Mr. Watson saw it at 550 yards. 

 Mr. Bailey found in Borrowdale, in June 1865, a monstrosity 

 with free petals. 



692. Erica cinerea, L. (Fine-leaved Heath). Native. 

 British type. Range 1-2. Common on the drier hills ; 

 ascending to 550 yards on Great Gable. 



695. Calluna vulgaris, Salisb. (Ling). Native. British 

 type. Range 1-3. Everywhere the common heather of the 

 moors ; ascending from the shore peat-mosses at Meathop to 

 900-1000 yards on Skiddaw. 



699. Andromeda polifolia, L. Native. Intermediate type. 

 Range 1.
