Klaseopsis and Archiserratula —two new genera segregated from Serratula (Compositae, Cardueae)

Serratula chinensis and S. forrestii , both endemic to China, have been shown to be phylogenetically separated from all other species of Serratula and from each other in a previous molecular analysis, and are placed in the newly described genera Klaseopsis and Archiserratula , respectively. Full descriptions including illustrations are presented.
