A herb which grows over 1 or 2 years. It has spreading stems and irregular branching. The plant is covered with bristly hairs. These are fattened at their bases. There are hooked prickles at the tips of the leaves. The lower leaves are sword shaped and can have a few teeth. They narrow into the leaf stalk. The upper leaves are smaller and do not have leaf stalks. They clasp the stem at the base. The flower heads often occur singly. The flowers are yellow.
