With the present study, we aim to contribute to the taxonomy of Tragopogon porrifolius L. (Asteraceae) in Turkey. This taxa is mainly distributed in Mediterranean regions of Europe including Turkey, however it is also growing in other parts of northern Europe. Plant samples using in the present study were collected during the field trip between 2014 and 2016 in Turkey and identified by using all relevant literatures. The plants are 24–92 (–120) cm in height, sometimes branched in upper parts and leaves are somewhat grass like. According to recent literatures, this complex consists of five subspecies excluding subsp. abbreviatus (Boiss.) Coskunc. & M. Gultepe endemic to Turkey, but present findings shows that subsp. eriospermus (Ten.) Greuter (T. porrifolius) should be distinct species rather than as subspecies and subsp. longirostris (Sch.Bip.) Greuter (T. longirostris Sch.Bip.) should be treated under the T. coelesyriacus Boiss. due to priority of fundamental principle in botanical nomenclature. Furthermore subsp. abbreviatus regarded as a synonym of subsp. longirostris according to several online taxonomic database and literatures, should be distinct subspecies of T. coelesyriacus. Thus it was combined as T. coelesyriacus subsp. abbreviatus (Boiss. ex Coskunc. & M. Gultepe) Coskunc. & M. Gultepe in the present paper.
