grows more copiously on clayslate than on limestone ; so 

 much so, that on a hill at the entrance of the Vale of Llan- 

 goUin, where these formations unite, their junction may 

 be traced by its abundance on the former, and almost total 

 absence on the limestone." On the contrary, Mr. C. Con- 

 way reports that, in Monmouthshire, this plant is abundant 

 on the limestone. In my own neighbourhood, in Svurey, 

 it prevails on sand, sandy peat, and even sandy clays; 

 while it shuns the tracts where the London clay comes 

 near the surface, with overlaying gravel or loam ; but I am 

 not clear that the undulated character of the surface in the 

 former, as compared with the level and less shaded latter 

 tracts, may not have its share of influence.

Alien. This species has become so well established in 

 some places in the Southern provinces, as to be deemed 

 " undoubtedly wild ;" but I must concur with the authors 

 of our descriptive Floras and Catalogues of British plants, 

 in holding it to be an introduced species.
