Taxon discussion

A Euro-Siberian floristic element reported twice in Greece: on the high-altitude serpentine rocks of Mt. Smolikas ( Lack and Kilian 1991) and on the northern foothills of Mt. Olimbos ( Strid and Franzén 1984). Lack and Kilian (1991) recorded the species as Scorzonera austriaca and noted that the Mt. Smolikas population is somehow intermediate between subsp. Scorzonera austriaca austriaca and subsp. Scorzonera austriaca bupleurifolia (Pouzolz) Bonnier. The Mt. Achladovouno population (Fig. 9 ) is new for the NE region and comes closer to the typical subspecies because of its basal leaves with lamina gradually narrowed into the petiole ( Chater 1976). Nomenclature follows Zaika et al. (2020), who transferred Scorzonera austriaca to Takhtajaniantha , in accordance with carpological, anatomical and molecular phylogenetic evidence.
