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

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 toTurkey is raised at specific level based on morphological and molecular analysis. After detailed assessment of original herbariumspecimens and literature studies, we found that this name is not typified yet. Thus, a lectotype is provided together with an emendeddiagnosis; synonym, distribution map, and conservation status for the first time. Additionally, a preliminary phylogenetic position ofthis little-known taxon is given on several newly sequenced data.
