英文摘要: Illiciaceae and Schisandraceae, together with other members of Austrobaileyales have been identified as one of the earliest diverging lineages of angiosperms, within the ANITA grade The specialized Illiciaceae and Schisandraceae comprise a clade defined by apomorphic characters including pollen grains with three or six colpate apertures. In both these families, pollen apertures and exine sculpture were found to be very informative when considered in the context of recent understanding of evolutionary patterns In the current study, pollen grains of 21 taxa from Illicraceae and Schisandraceae were investigated. These data, together with palynological data for taxa previously studied, were mapped into recent molecular phylogenetic trees to re-evaluate the existing classification and phylogenetic relationships in the two families Palynological data were found to be relatively congruent with recent molecular phylogenies, while traditional delimitations of infra-generic taxa were somewhat conflicting and did not reflect phylogeny and evolution The evolution of pollen morphology in the two families, together with other members of Austrobaileyales, is discussed in comparison with the molecular phylogenies (C) 2009 Elsevier GmbH.
