Native. Sylvestral, &c. Abimdant in many places in 

 the southern provinces ; scarce or local in the northern 

 provinces of England ; and though Dr. Robert Graham

 of Edinburgh and Fife, by other botanists, this was done 

 under a scarcely veiled distrust. The Catalogue of the 

 Edinburgh Botanical Society gives the species as very rare 

 and doubtfully native in their circuit.
