ResumoBased on results from cladistic analyses of morphology and DNA sequences (the two chlo- roplast genes rbcL and ndhF), the three Australasian families Alseuosmiaceae, Argophyllaceae, and Phelli- naceae are each monophyletic, belong within Asterales, and together form a monophyletic group. Two new rbcL sequences and thirteen new ndhF sequences were obtained. Congruence tests did not reveal any signif- icant incongruence between the two molecular data sets or between the molecular and morphological data. The character evolution of the Alseuosmiaceae-Argophyllaceae-Phellinaceae group is discussed. The Austra- lasian ancestor of this group was probably a woody plant with simple, alternate, serrate leaves and regular, choripetalous, epigynous flowers borne in panicles. All three families should be retained in line with the principle of ease of identification.
