<i>Scorzonera ahmet‐duranii</i> sp. nov. (Asteraceae) from southwest Anatolia, and its phylogenetic position

Abstract

Scorzonera ahmet‐duranii S. Makbul &amp; Coskuncelebi sp. nov. (Asteraceae) is described and illustrated as a new species endemic to Turkey. It is morphologically similar to S. semicana DC., but differs by its rootstock, deeply undulating basal leaves and glabrous achenes. Additionally, the size and micro‐morphological properties of achenes and some anatomical traits of the leaf and stem are helpful in distinguishing these closely related taxa. A phylogenetic analysis based on nrDNA ITS sequence data showed that S. semicana is the sister species of the new taxon presented in this study.
