 in gravel-pits, and about hedges and road-sides, it may 

 pass muster with the natives.

Native. Pascual, &c. As fai" north as Breaston, in the 

 south of Derbyshire, whence I have a specimen, from Dr. 

 Howitt, collected by Mr. Davidson. Recorded in the Bo- 

 tanist's Guide, as found by Mrs. Wharton, near Siggles- 

 thorne, on the east coast of Yorkshire. We are told that 

 " this plant grew between the Glass houses and Dent's 

 Hole, Newcastle," in the time of Lawson. Mr. Embleton 

 intimates to me that it has occurred (to whom ?) near 

 Leitholm, in Berwickshire. I hesitate to give the northern 

 range beyond Derbyshire, until confirmed.
