Claspleaf Pennycress

A winter annual weed of roadsides, landscapes and occasionally no-tillage agronomic crops. Basal rosette leaves occur on petioles, are without hairs, and are elliptic to oblong in outline. Leaves on the flowering stem have rounded bases that clasp the stem and become progressively smaller toward the top. Flowers occur in the upper portions of the terminal inflorescence and are very small (3 mm long, 1 mm wide) and consist of four white petals with yellow anthers in the center. The fruit closely resembles that of shepherd’s-purse, but is generally more heart shaped, less triangular in outline, and larger than that of shepherd’s-purse.
The stem of field pepperweed comes out of a basal rosette of toothed leaves. The stem is covered in leaves, which are sessile, alternate and arrow-shaped. The entire plant is generally between 20 and 60 cm tall and covered in small hairs
