 soil, Ohio and Minn, west to Col. Also an 

 escape from gardens in the east. 



An annual species naturalized from 

 Europe, with a smooth, erect, stout stem, 

 often branched from the base. Leaves 

 obovate and finely toothed. The insignifi-

A perennial spreading by horizontal 

 rootstocks, and an escape from gardens 

 to roadsides and waste places in the east- 

 ern States. Leaves bright light green, 

 linear and almost filiform. The stems 

 thickly clustered and very leafy, ter- 

 minated by a large flower-cluster flat 

 dome-shaped. The insignificant flowers 

 indeterminate in color, but generally greenish dull yel- 

 low, or tan, or russet red ; they are rather ornamental, 

 with crescent-shaped glands. The plant is milky juiced, 

 like all the Euphorbias, and it has become naturalized 

 from Europe. It is poisonous if eaten in any quantity. 

 Fertilized by bees and butterflies. 5-12 inches high. 

 Common everywhere in the east. Found in Campton, 

 N. H., near an old graveyard.
