HIERACIUM DOVRENSE. Fr. 



Stated by Pries (Symb. Hier., p. 129) to have been found in 

 Scotland, but not known by British botanists to exist there. 



HIERACIUM RIGIDUM. llartm. 



Said to occur in Scotland by Pries ; but the plant he supposed 

 to be that is, according to Mr. Backhouse, a form of H. co- 

 rymbosum. 



XANTHIUM SPINOSUM. Linn. 



Dr. H. Bull and Mr. G. S. Wintle have both sent me this 

 plant from Hereford, where it appeared in abundance on ground 

 on which mud from the streets of the town had been laid. It 

 is too tender to have any chance of becoming permanently natural- 

 ized in Britain. Dr. Bull informs me that it has also occurred in 

 Wales.
