CHENOPODIUM 419 



Cultivated fields, waste places, manure-heaps, &c. Common and 

 widely distributed. 



Boreau says the three varieties come true from seed. In many cases small 

 distinctions and trifling characters are perpetuated, i. e. the white form of 

 Geranium Robertianiim. 



The varieties mentioned above by no means exhaust the forms grouped 

 under C album. While var. candicans is fairly distinct, the gap between 

 var. paganum and var. viride is bridged over by a series of intermediate 

 forms. Var. candicans itself varies considerably in leaf-cutting ; an entire- 

 leaved form is found. 



C. albmn is found in all the bordering counties.
