Native tansy mustard or pinnate tansy mustard: (p. 153, Weeds of the Midwest; pp. 206-207, Weeds of the Great Plains; not in Weeds of the Northeast)
- very closely resembles flixweed, but is a native species
- but siliques are shorter (0.5-1.0") and are held out away from and parallel to flowering stem
- leaves are more ruffly
- also can be a weed problem, but not as bad as flixweed
