Native. Sylvestral, &c. The name of this present spe- 

 cies has been so fiequently given to specimens of P. media 

 and P. minor, that comparatively few of the recorded lo- 

 calities can be relied upon as certainly correct. In addition 

 to the counties mentioned above, it is probable that those 

 of Lancastei', York, Durham, Northumberland, and per- 

 haps Benvick, may be trusted. But those of Devon, 

 Sussex, Oxford, Gloucester, Worcester, Salop, Stafford, 

 Westmoreland, Cumberland, Lanark, Edinburgh, Aber- 

 deen, Orkney, and Shetland, are all of them to be dis- 

 trusted ; and, probably, most of them are erroneously 

 recorded for P. rotundifolia. I have only once met with it 

 at a considerable elevation, namely, in Glen Clova, Forfar- 

 shire ; and the altitude there has been estimated, from no 

 very precise data, at 800 yards.
