The genus Scorzonera L. (Asteraceae), with about 160 species belonging to the subtribe Scorzonerinae Dumort. of the tribe Cichorieae, is widespread in the more arid regions of Eurasia and northern Africa (Bremer and Anderberg, 1994;Nazarova, 1997).After the genus Scorzonera s.str. was revised by Chamberlain (1975) for the Flora of Turkey, many new species have been recorded from Turkey. The classification of the genus has been highly controversial (Nazarova, 1997;Mavrodiev et al., 2004), and because of this different taxonomic treatments have been used in the floras. Starting with De Candolle (1805), frequently Scorzonera species with a conspicuous cylindric carpopodium were placed under a separate genus,
Morphological measurements and micromorphological photographs were done with a Leica S6D microscope. Herbarium specimens were photographed with a Canon
The new species, Tragopogon anatolicus A.Duran, B.Doğan & Coşkunç. sp. nov. (Asteraceae) is described and illustrated from Cilo Mt. (Hakkari), south-east Anatolia, Turkey. Tragopogon anatolicus is a local endemic, most similar to T. buphthalmoides (DC.) Boiss. Diagnostic morphological characters of these two closely related taxa are discussed. A phylogenetic analysis based on nrDNA ITS sequence data indicated that T. buphthalmoides is the sister species of the new taxon. Ecology, biogeography and conservation status of the new species are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
