Extract

The weedy annual and perennial members of Euphorbia are widespread in the United States, occurring in every state. In at least nineteen states E. esula is considered serious enough to be declared noxious by law (PMA, 1946). In other states, to date, the members of this group occupy the position of a minor nuisance, to be controlled in the general clean-up of other weeds. E. corollata is noxious in Idaho and Wyoming; E. lucida in Idaho and South Dakota.
