Plants from C. Europe are sometimes regarded as a separate species, C. hispida (L.) Hayek , Fl. Steierm. 1: 478 (1908), and those from N.E. Russia are distinguished as C. septentrionalis (N. Busch) O. E. Schulz in Engler, Natiirl. Pflanzenfam. ed. 2, 17 b: 541 (1936), but the characters separating them from C. petraea are by no means clear.
