Club 26 ; 124. 1899, Much like L. ruderale and L. virgiiiicum. Basal leaves pinnately lobed or pinnatifid. Pods obovate-orbicular to ovate, sometimes broader than long, slightly wing-margined above, about i" in diameter; tlowering pedicels ascending, forming narrow racemes, or in fruit spreading; petals small or wanting; seeds nearly wingless; cotyledons incumbent. In dry soil, Maine and Ontario to British Co- lumbia, Virginia, Texas and Nevada. Naturalized in Europe and native also of Asia. May-Aug. Has been confused with the Asiatic L. apetalum Willd. and with L. medium Greene. Lepidium neglectum Thellung, differing by slightly longer capsules with more distinctly winged seeds, is widely distributed within the range of the preceding species and is also natural- ized in Europe ; but it does not appear to be spe- cifically distinct. 6.
