Lectotype.

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

Note.

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.
