The leaflets have petioles and are egg-shaped, cordate at the base, with coarsely serrate margins and stipules without petioles. The dark red flowers are arranged in spherical, egg-shaped heads.
To the left: Centaurea scabiosa (Greater Knapweed, Asteraceae): The leaves are pinnate with broad, lanceolate segments. - To the right: Knautia arvensis (Field Scabious): a case of heterophylly: Leaves of more than one type spring from one shoot. The leaves at the stem are opposite, the lower ones have petioles, are of a lanceolate shape, have serrate margins and are often pinnate. The middle and upper leaves are sessile, pinnate with 3 - 6 segments at each side.
