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

Abstract

Tragopogon L. (Asteraceae) includes several cryptic species that are geographically widespread and morphologically similar. Here, we describe two new native species from eastern Anatolia. Through both morphological and molecular data, we present diagnostic characteristics, descriptions, pollen grains and micro‐ and macro‐morphological properties of achenes, as well as the conservation status of the newly described species. Current morphological and molecular results support treating T. reticulatus Boiss. & Huet and the two newly described taxa under the section Profundisulcati Kuthath. Molecular phylogentic reconstructions based on ITS data show that T. longirostris Sch. Bip. is a distinct species rather than a subspecies of T. porrifolius L. (T. porrifolius subsp. longirostris (Sch. Bip.) Greuter) and that ligule colour is not a taxonomically important trait at the subrageneric level.

Tragopogon abbreviatus (Asteraceae): a little-known species inferred from morphological and molecular analysis

“…longirostris from T. porrifolius as previously suggested by Greuter (2003). Gültepe et al (2016) also made similar taxonomical comment about T. longirostris var. longirostris.…”

“…Coşkunç and M.Gultepe) contrary to Greuter (2003). Besides Gültepe et al (2016) reported, contrary to Greuter (2003), that T. porrifolius and T. longirostris should be treated as separate species based on molecular data. Correspondingly, the aim of the present study is to identify the authentic material of the name T. longirostris var.…”

“…Amplification and sequence of nrDNA ITS regions were carried out according to Gültepe et al (2010). Phylogenetic analyses were performed on the ITS data set consisting of 87 accessions (Table 1), of which 15 were newly generated sequences, 72 sequences were obtained from GenBank and 10 were used as an outgroup provided from Gültepe et al (2016). For each taxon, multiple samples were used whenever possible to observe the infra-specific DNA sequence variation and construct a robust phylogenetical analysis.…”

“…Meanwhile the related literature (Behçet, 2001;Doğan and Akaydın, 2004;Özgökçe et al, 2005;Sutorý, 2005;Akan et al, 2008;Karabacak and Behçet, 2009;Dirmenci et al, 2010;Eker and Babaç, 2010;Yıldırım et al, 2011;Yıldız et al, 2011;İlçim et al, 2013;Vitek et al, 2014;Yıldırırm, 2014;Doğan et. al., 2015;Tekşen and Karaman, 2015;Fırat and Yıldız, 2016;Gültepe et al, 2016;Fırat, 2017a,b;Pınar, 2017) concerning the endemic plant taxa of Van Lake basin were also traced, and an endemic plant list with 259 taxa was created. Collection localities are given in Table 1.…”

Contribution to the taxonomy of little known Tragopogon species endemic to Turkey

“…1977), a sectional classification was not proposed in the Turkish Tragopogon account by Matthews (1975). However, Gültepe et al (2016) suggested that Turkish Tragopogon species should be treated under eight sections according to Borisova's (1964) system. Following Borisova (1964), T. olympicus should be treated under Tragopogon sect.…”
