[Overview]
An annual 10–60 cm tall, found on the banks of rice paddies and in ditches.
The stems and leaves bear short stiff hairs and are rough to the touch.
The leaves are simple and opposite, lanceolate to elliptic-lanceolate, 3–10 cm long and 0.5–2.5 cm wide, with serrated margins.
The flower heads are borne in the leaf axils and at the stem tips; white ray florets are arranged in two rows around the edge, and the central tubular florets are also white.
The fruit is an achene, with wings on the edge and a wart-like projection only in the center of the side.
