Tragopogon turcicus sp. nov. (Asteraceae) from Turkey and its phylogenetic position

Abstract

Tragopogon turcicus Coşkunç., M.Gultepe & Makbul, a new diploid species (2n = 2x = 12), is described and illustrated from Kızıldağ National Park (Isparta), southwest Anatolia. It is morphologically similar to T. oligolepis Hartvig & Strid which is also endemic to Turkey. Diagnostic characters, description, conservation status together with micro‐ and macro‐morphological properties of achenes and pollen grains are given. A phylogenetic analysis based on nrDNA ITS sequence data indicated that T. oligolepis is the sister species of the new taxon.

Taxonomic notes on Tragopogon, and two newly described taxa from Anatolia

“…They reported that achene characteristics were very useful for the separation and identification of different taxa within the genus. Similarly, Dogan et al (2014) and Gültepe at al. (2015b) reported that macro-and micro-morphological characters of the achenes are associated with separation of Turkish Tragopogon.…”

“…), as reported by Wodehouse () and Blackmore (). Suboblate (İnceoğlu and Karamustafa , Gültepe et al ) and oblate‐spheroidal (Blackmore , Dogan et al ) have previously been reported in Tragopogon . As seen in Table , the suboblate and oblate‐spheroidal pollen grains identified in the present study were consistent with previous findings.…”

“…Amplification and sequencing of ITS regions were performed as described by Gültepe et al (). Sequence data of Coşkunçelebi et al (), Dogan et al (), and Gültepe et al () were used in phylogenetic analysis except for T. pterocarpus (Coşkunçelebi and Gültepe 150 KTUB) which was not sequenced before from Turkey. All sequences (32 accessions) were aligned with Bioedit v. 7.0 (Hall ) before being subjected to maximum parsimony (MP) analysis.…”

“…Coşkunçelebi and Gültepe (2012) concluded that 21 species, including doubtful records, are distributed in Turkey. However, the number of Turkish species reaches 23 if two recent papers by Dogan et al (2014) and Gültepe et al (2015b) are considered.…”
