Introduced. Annual and winter annual. Propagates by seeds. Time of bloom: May to August. Seed-time: June to September.

Range: Maine, New York, and Ontario, to the Northwest Territory, California, and Texas. Habitat: Grain and clover fields, waste places.

Similar to the native plant, but has pinnatifid root-leaves, the stem-leaves are fewer and more slender, and the white petals of the flowers are very minute, sometimes entirely lacking. The rounded and notched pods have a minute wing-margin at the top, slightly more pronounced than in the preceding species. (Fig. 122.)

Means of control the same as for Shepherd's Purse.
