Ambrosia bidentata is an annual herb up to 100 cm (40 inches) tall. Leaves have only a few lobes compared to the complexly divided leaves of some related species, sometimes no lobes at all. Flower heads are small and inconspicuous, as the plant is wind-pollinated. The heads develop into spiny burs as the seeds ripen.[3]
