Abstract
Dipsacus sylvestris Huds., wild teasel, is an introduced weed of pastures, abandoned fields and roadsides occurring in widely-spaced but very dense patches in southern Ontario, Quebec, northeastern U.S.A., and northwestern U.S.A. Original research and information from other studies are incorporated into a summary of the biology of this fugitive plant species.
