(Mrs. EusseU, &c.), Hereford (Mr. A. T. Wilmott). Al- 

 though these localities are all on the western side of 

 England, I do not refer the distribution of the si^ecies to 

 the Atlantic tj'pe, because the area as a whole is rather 

 midland than strictly western.

Native. Sylvestral, Eupestral. This species has a dis- 

 tribution very similar with that of C. clandestina, except 

 by its reappearance in two of the northern provinces of 

 England. It occurs in Somerset, Wilts, Gloucester, He- 

 reford, Nottingham, and York. The county of Derby 

 requires verification, but is not improbable ; it rests on 

 the authority of Mr. Salt, in Mr. Winch's manuscripts. 

 Mr, Withers estimates the altitude of stations in wlaich 

 this species grows, at 50 yards in Somerset, and at 100 

 yards in Monmouthshire.
