Two new species ofCentaurea (Compositae, Cardueae) from Turkey

摘要

Two new species of Centaurea collected by R. Ulrich in southern Anatolia are described, mapped and illustrated. C. ulrichiorum is apparently very isolated and cannot be assigned to any of the known sections; molecular data place it in a clade comprising, e.g., the sections Jacea and Acrolophus. C. werneri is a member of C. sect. Acrolophus with affinities to species of the Balkans.
