TAXONOMY AND PHYLOGENY OF THE TRIBE INULEAE (ASTERACEAE)

The interrelationships of the tribe Inuleae s. str. have been analysed with a computerized parsimony program (Hennig 86), using the Arctotideae as functional outgroup. The results are illustrated with a cladogram and a strict consensus tree. A detailed character discussion is presented. Descriptions of all genera are supplied with brief notes on distribution, references to chemical investigations, and chromosome numbers. Lists of recognized species are also presented in connection to each genus, respectively. 21 new combinations are made, one new genus, Xerolekia A. ANDERB., is described, Mollera is reduced to a synonym of Calostephane, and the genus Duhaldea is resuscitated. Anisopappus was found to be a paraphyletic basal group in the tribe. The paleate genera Asteriscus, Nauplius, Ighermia, Buphthalmum, and Xerolekia form one monophyletic group, Inula and other, similar genera were found to constitute the ancestral complex of the Pulicaria group.
