Denizen. Glareal. In the British Flora, this is marked 

 as a species " naturalized by the agency of man ;" in the 

 Manual of British Botany, it is given as a genuine native. 

 I find it recorded from the counties of Devon, Dorset, 

 Sussex, Kent, Surrey (Mr. Ellis, ms.), Hertford, Suffolk, 

 Norfolk, Cambridge, Glamorgan, York and Northumber- 

 land. Devon stands upon the uncorroborated authority 

 of Polwhele. The Report, by Webb and Coleman, leaves 

 Hertford in an equally unsatisfactory condition. In Gla- 

 morganshire, Mr. E. Forstersaw "Medicago falcata, floribus 

 purpureis," which was probably some mistake about M. 

 sativa. A locality, " near Hovingham," is recorded.in the 

 Yorkshire Flora ; and another, " on ballast hills," &c., in 

 that of Northumberland and Durham. The species may 

 be native in Norfolk, Suffolk, and some other eastern 

 counties, south and west of those two.

Native. Agrestal, &c. Even this plant, so profusely 

 abundant in England, is apparently not general in its distri- 

 bution ; being wholly omitted fi*om the lists of species 

 ascertained in the three groups of the North Isles, and 

 equally so from my own notes of those observed in Suther-
