Petals red or reddish, elliptic-oblanceolate, ca. 1.2 cm × 1.5 mm; claw glabrous; limb apex obtuse-rounded. Stamens exserted, ca. 1.4 cm. Ovules 4. Style exserted. Capsule not seen. Fl. Jun--Aug.

In FRPS, Acanthophyllum spinosum (Desfontaines) C. A. Meyer was treated as a synonym of A. pungens . However, the present account follows Schiman-Czeika (in Rechinger, Fl. Iran. 163: 285–286. 1988) in treating A. spinosum (including A. fontanesii Boissier) as a separate species restricted to Afghanistan and Iran.
