Abstract

Centaurea cadmea Boiss. subsp. pontica Wagenitz ex Y.B. Köse & Ocak (Asteraceae), a new subspecies occuring in north Anatolia, Turkey, is described and illustrated. The new subspecies grows in rocky places in the Zonguldak province. It is closely related to C. cadmea subsp. cadmea , but differs in its involucrum, achen, appendage and radiant flowers. Diagnostic morphological characters are discussed and notes are presented on ecology and conservation status. In addition, the pollen characteristics of both subspecies have been examined by SEM.
