H. litoreum Guss. , FI. Sic. Syn. 2: 468 (1844) combines the 30-60 mm long, linear leaves of some variants of 6 with the small cylindrical capitula of 10, but the involucral bracts are less regularly imbricate, and the outer bracts are often subacute and somewhat longer than in 10. It occurs on coastal cliffs and rocks in S. Italy and the Sicilian archipelago, but not in Sicilia itself.
