Athroismeae is a small tribe of the Asteraceae‐Asteroideae, the members of which show considerable variation in morphology. A molecular phylogenetic study of the tribe is presented for the first time, based on plastid ( ndhF, trnH‐pssbA, trnL‐trnF ) and nuclear data (ETS, ITS). The phylogenetic relationships between the different genera within Athroismeae are discussed, and in addition, three unispecific genera: Anissochaeta, Artemissiopssiss and Symphyllocarpuss as well as Duhaldea ( Inula ) sstuhlmannii , all earlier placed in other tribes, are here shown to belong within Athroismeae. Symphyllocarpuss is sister to Centipeda and the earlier Symphyllocarpinae includes Centipedinae in synonymy. Furthermore, Cardossoa and Philyrophyllum are found to be integrated within Anissopappuss and their generic status cannot be maintained. An outline of an amended circumscription of the Athroismeae is presented, with three new combinations and a description of the new subtribe Lowryanthinae.
