A conspectus of Scorzonera s.l. in Turkey

Abstract

A comprehensive taxonomic study based on comparative morphology of Scorzonera , here maintained in its wide sense, is presented for the territory of Turkey. Tis study has produced several changes of classifcation at sectional and species ranks. An updated list of Scorzonera taxa occurring in Turkey, along with their infrageneric classifcation, is provided. A new section, S. sect. Anatolia Makbul & Coskunç., is described. Chromosome numbers, threat categories, and distribution maps are given for 6 endemic taxa (S. boissieri, S. karabelensis, S. longiana , S. sandrasica , S. ulrichii, and S. zorkunensis) placed in or transferred to the newly described section. A revised identifcation key to all Scorzonera species in Turkey is presented.
