The Euro+Med treatment of Senecioneae and the minor Compositae tribes — generic concepts and required new names, with an addendum to Cardueae

Abstract

Asynonymic survey of genera in the Senecioneae accepted for the purposes of the Euro+Med Project is presented, and new combinations that are required in the genera Adenostyles, Doronicum, Senecio and Tephroseris (including a new subspecies), as well as Xanthium in the Heliantheae, are validated. Five validations concerning Cardueae taxa, three in Centaurea, one in Psephellus, and one in Rhaponticum, are appended. A synopsis of accepted genera (including many exotic aliens) in nine minor tribes (Arctoteae, Calenduleae, Eupatorieae, Gundelieae, Helenieae, Heliantheae, Mutisieae, Plucheeae, Vernonieae) completes the generic survey of European and Mediterranean Compositae.
