Scorzonera L., Sp. Pl.: 790. 1753.  


(Green in Hitchcock and Green 1929: 177): Scorzonera humilis   L.


Scorzonera   in this revised sense as a monophyletic genus includes four larger clades, the Scorzonera   s.str. clade (3 spp.), Scorzonera albicaulis   clade (~17 spp.), Podospermum   clade (~20 spp.) and Scorzonera purpurea   clade (2 spp.). In addition, it includes a few, so far somewhat isolated species ( S. rupicola   , S. renzii   , S. angustifolia   ). The genus in this cricumscription still shows considerable variation. Our analysis is insufficient with respect to a revision of the elaborated infrageneric classifications of previous authors. We therefore refer here to the clades of our trees.
