Lepidium campestre A. A. Reznicek

An introduced Eurasian species, now quite widespread in the state. Roadsides, railroads, sandy fields, sandy and gravelly shores, and other disturbed sites, sometimes spreading into dry forests. First collected in the state in 1892 in Ingham Co., but very soon afterwards collected at several places across the state.

Distinctive in its dense pubescence and sagittate-clasping leaves, yet surprisingly often other species of the genus and even plants of other genera are misidentified as L. campestre. The unique fruit is somewhat oblong (rather than round as in the other species), and inflated in the middle (rather than flat), though still bordered with a distinct flat wing; furthermore, it is covered with minute pale papillae.
