Winter annual broadleaf
A winter annual weed of agronomic crops found throughout much of the United States. Seedlings have spoon-shaped cotyledons that are notched at the tip. Mature plants have leaves that are alternate and linear in outline. Basal leaves are generally more lobed and have wavier margins than those of stem leaves, which have entire margins and are more linear in outline. Basal and stem leaves are covered with short hairs. Flowers are relatively small and pale yellow in color. The fruits are long, slender pods that are very noticeable at maturity.
