CHENOPODIUM 417 



Native. Glareal, agrestal. Sandy cornfields and heathy ground. 

 Locally abundant, and although absent from large areas of the 

 Clays and Chalk, yet too widely distributed to need the mention 

 of localities. A. or B. March-September. 

 First recorded in Russell's Newbw-y Catalogue, 1839. 



Var. BIENNIS (Renter, in Compt. Rend. Soc. Hall. (1853-4) 20, 

 as a species), Syme, I.e., t. 1175, is found more usually in untilled 

 ground where the plant is undisturbed. I have seen it on Boar s 

 Hill, near Padworth, at Snelsmore, and at Sunninghill. I am in- 

 clined to think with the Rev. E. F. Linton that this species has 

 become more frequent owing to the culture of soils, and that S. aunuus 

 may have been evolved from the original biennial plant.
