From the Namib around the world: biogeography of the Inuleae–Plucheinae (Asteraceae)
Abstract Aim We investigated the historical biogeography of the Inuleae–Plucheinae (Asteraceae), a group of arid‐adapted plants with partly unresolved generic circumscriptions, in order to understand its origin and spatiotemporal evolutionary history in relation to the Cenozoic climate shifts.

Main conclusions The origin of the Plucheinae is estimated to the Namib region, with early speciations and radiations concurring with the timing of aridification of southern Africa, following the increase in strength of the Antarctic Circumpolar Current and subsequent formation of the Benguela Upwelling at c . 11.8 Ma. The current biogeographical distribution of the Plucheinae is best explained by several Neogene long‐distance dispersal events from tropical Africa.
