TAILIEUCHUNG - A new Scorzonera (Asteraceae) species from South Anatolia, Turkey, and its taxonomic position based on molecular data

Scorzonera zorkunensis Coskuncelebi & (Asteraceae) is described and illustrated from Turkey. It grows on serpentine in alpine steppe vegetation together with several endemic Scorzonera L. species in southern Anatolia at altitudes of 2075-2100 m. It is morphologically similar to S. pisidica ., but it differs in its habit and stem and leaf pubescence. | K. COŞKUNÇELEBİ, S. MAKBUL, M. GÜLTEPE, D. ONAT, M. E. GÜZEL, S.

It grows on serpentine in alpine steppe vegetation together with several endemic Scorzonera L. species in southern Anatolia at altitudes of 2075-2100 m. It is morphologically similar to S. pisidica ., but it differs in its habit and stem and leaf pubescence. Additionally, the size and micromorphological characters of the achenes and some anatomical traits of the leaves, stems, and roots are helpful in distinguishing these closely related taxa. The phylogenetic analyses based on nrDNA ITS sequence data indicate that S. pisidica is a sister species of the new taxon.

Bu yeni tür, bir çok endemik Scorzonera L. taksonu ile beraber alpin steplerdeki serpantin yerlerde yayılış göstermektedir. Yeni tür morfolojik olarak S. pisidica . türüne benzemesine rağmen yaşam alanı, yaprak ve gövde tüylenmesi bakımından ondan kolaylıkla ayrılmaktadır. Ayrıca meyvenin (aken) büyüklüğü ve mikromorfolojisi, kök, gövde ve yaprak anatomik özellikleri bu iki türün .
