Abstract
Tragopogon porrifolius occurs in Turkey with 3 taxonomically confused subspecies: T. porrifolius subsp. eriospermus, T. porrifolius subsp. longirostris, and T. porrifolius subsp. abbreviatus. In the present paper, T. porrifolius subsp. abbreviatus endemic to Turkey is raised at specific level based on morphological and molecular analysis. After detailed assessment of original herbarium specimens and literature studies, we found that this name is not typified yet. Thus, a lectotype is provided together with an emended diagnosis; synonym, distribution map, and conservation status for the first time. Additionally, a preliminary phylogenetic position of this little-known taxon is given on several newly sequenced data.
Highlights
Tragopogon L. (Asteraceae) includes about 150 species native to Eurasia and known as salsify worldwide (Bremer, 1994; Soltis et al, 2004) and 22 species (25 taxa) in Turkey (Coşkunçelebi et al, 2017)
Further comparisons based on several morphological features that are important for the genus Tragopogon (Blanca and Diaz De La Guardia, 1997; Sukhorukov and Nilova, 2015) revealed that these samples distinctly differ from T. porrifolius subsp. longirostris (=T. longirostris var. longirostris) and T. porrifolius subsp. eriospermus (Ten.) Greuter (=T. porrifolius var. brachyphyllus Boiss)
T. abbreviatus was firstly described as a variety of T. longirostris based on specimens of Boissier, Bourgeau, Calvert, and Koch collected from different parts of Turkey
Summary
Tragopogon L. (Asteraceae) includes about 150 species native to Eurasia and known as salsify worldwide (Bremer, 1994; Soltis et al, 2004) and 22 species (25 taxa) in Turkey (Coşkunçelebi et al, 2017). Abbreviatus, he reported that it differs from T. longirostris var. Later Coşkunçelebi et al (2017) reported that T. dshimilensis is an accepted taxon endemic to Turkey due to differences in During a taxonomic revision of the Turkish Tragopogon, the authors collected several specimens keying out T. longirostris var. Further comparisons based on several morphological features that are important for the genus Tragopogon (Blanca and Diaz De La Guardia, 1997; Sukhorukov and Nilova, 2015) revealed that these samples distinctly differ from T. porrifolius subsp. Brachyphyllus Boiss.) were treated as separate species by Matthews (1975) in the Flora of Turkey, Coşkunçelebi and Gültepe (2012) T. longirostris and T. porrifolius (=T. porrifolius var. brachyphyllus Boiss.) were treated as separate species by Matthews (1975) in the Flora of Turkey, Coşkunçelebi and Gültepe (2012)
