Centaurea ptosimopappa var. elegans Güzel. A New Centaurea L. (Asteraceae) taxa from Turkey with taxonomical notes on sect. Ptosimopappus and with lectotypification

A new variety of Centaurea (Asteraceae) section Ptosimopappus from the Amanus Mountains, South Anatolia was described. The new taxon is considered as a variety of C. ptosimopappa due to shared morphological characters such as sterile and fertile leathery basal rosettes and branched shrub habits. On the other hand, it differs by achene morphology and by involucre, spinule and cauline leave sizes as well as other morphological and anatomical differences. Detailed morphological, carpological and microsculptural analyses were carried out in order to reveal the differences between the variety. Also, Lectotype for C. ptosimopappa var. ptosimopappa based on isotypes of its basionym Ptosimopappus bracteatus was designated
