A New Subfamily of the Asteraceae

The Asteraceae are generally divided into two large subfamilies, the Cichorioideae (syn. Lactucoideae; tribes Mutisieae, Cardueae, Lactuceae, Vernonieae, Liabeae, Arctoteae) and the Asteroideae (Inuleae, Astereae, Anthemideae, Senecioneae, Calenduleae, Heliantheae, Eupatorieae). Recent phylogenetic analyses based on morphological and chloroplast DNA data show that the Mutisieae-Barnadesiinae are the sister group to the rest of the family. The Mutisieae-Barnadesiinae are here excluded from the Mutisieae and elevated to the new subfamily Barnadesioidae
