Here we describe Centaurea hekimhanensis, a new species found in Hekimhan (Turkey, Malatya Province). This Centaurea grows on the stony-gravel mountain slopes of Yamadag and is morphologically similar to C. reuteriana, C. bourgaei, and C. pichleri in terms of their flowering lateral stem at the base of the rosette, but differs regarding the shape of the stem and rosette leaves, and the size of the rosette leaves and median appendages; the achene ornamentation is irregularly sulcate. The chromosome number of the new species is 2n = 20. ; Scientific Investigation Project Coordinator of Selcuk University [15101001] ; We would like to thank the curators of the ANK, GAZI, ISTF, ISTE and KNYA Herbaria for their helpful assistance and Meryem BOZKURT for her assistance in chromosome studies.
