Native. Sylvestral. There can be no doubt about the 

 occurrence of this species northward into Fife, and south- 

 ward into Hants. But the localities of Methven Wood, in 

 Perth, and the Isle of Arran, are assigned, by different ob- 

 servers, one while to E. grandiflora, one while to E. ensi- 

 folia. This circumstance tends to strengthen the suspicion 

 intimated in treating the preceding species, that some con- 

 fusion or mis-naming of the plants has occurred. On 

 looking to the line of nos. which indicate the " Area " of 

 the present species, it appears to be scattered too irregu- 

 larly for reference to any one of our six types very strictly 

 understood.
