Broad-scale phylogenetic analyses of the angiosperms and of the Asteridae have failed to confidently resolve relationships among the major lineages of the campanulid Asteridae (i.e., the euasterid II of APG II, 2003). To address this problem we assembled presently available sequences for a core set of 50 taxa, representing the diver- sity of the four largest lineages (Apiales, Aquifoliales, Asterales, Dipsacales) as well as the smaller “unplaced” groups (e.g., Bruniaceae, Paracryphiaceae, Columelliaceae). We constructed four data matrices for phylogenetic analysis: a chloroplast coding matrix (atpB, matK, ndhF, rbcL), a chloroplast non-coding matrix (rps16 intron, trnT-F region, trnV-atpE IGS), a combined chloroplast dataset (all seven chloroplast regions), and a combined genome matrix (seven chloroplast regions plus 18S and 26S rDNA). Bayesian analyses of these datasets using mixed substitution models produced often well-resolved and supported trees.

A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Previous attempts to resolve relationships among the primary lineages of Campanulidae (e.g. Apiales, Asterales, Dipsacales) have mostly been unconvincing, and the placement of a number of smaller groups (e.g. Bruniaceae, Columelliaceae, Escalloniaceae) remains uncertain. Here we build on a recent analysis of an incomplete data set that was assembled from the literature for a set of 50 campanulid taxa. To this data set we first added newly generated DNA sequence data for the same set of genes and taxa. Second, we sequenced three additional cpDNA coding regions (ca. 8,000 bp) for the same set of 50 campanulid taxa. Finally, we assembled the most comprehensive sample of cam- panulid diversity to date, including ca. 17,000 bp of cpDNA for 122 campanulid taxa and five outgroups. Simply filling in missing data in the 50-taxon data set (rendering it 94% complete) resulted in a topology that was similar to earlier studies, but with little additional resolution or confidence.

  • Good Grief, What's Happening to Goodenia? Kelly A. Shepherd1
    39 Phylogenetic placement and biogeographic history of the Australian Annonaceae Tanya Scharaschkin Earth, Environment and Biological Sciences School, Science and Engineering Faculty, Queensland University of Technology, George St, Brisbane, QLD 4001 Email: [email protected] The Annonaceae is a tropical flowering plant family consisting of c. 250 genera and approximately 2,500 species. Forty-eight species were described in a taxonomic revision of the Annonaceae in Australia, with a large number of species, and some genera, considered to be Australian endemics. The monophyly and taxonomic placement of all Australian Annonaceae are investigated using a comprehensive sampling of both Australian and non-Australian representatives from the same or closely-related genera. The results are used to evaluate biogeographic scenarios for a Gondwanan and/or Malesian origin for the Australian Annonaceae. The phylogenetic placement of the Australian taxa is consistent with studies on individual genera. The high level of species endemism seen in Australian Annonaceae is indicative of speciation subsequent to arrival from Asia, due to one or more dispersal or range extension events.

These include species with nearly radially symmetric flowers to several forms of zygomorphy, including bilabiate flowers among species of Goodenia and the enigmatic Detailed Programs fan‐flowers exemplified by, but not limited to, Scaevola. We aim to reconstruct the evolution of flower shape in the larger clade of this family (Core Goodeniaceae) to address Custom Schedule several questions: 1) How many times have fan‐flowers evolved? 2) Do some clades exhibit greater floral shape lability? 3) Do the dorsal petals evolve at a higher rate than the lateral Sessions or ventral petals? and 4) To what degree, if any, does floral shape influence diversification rate across the Core Goodeniaceae? Our highly resolved, densely sampled phylogenies for the clade provide the necessary historical structure. For the comparative floral data, we have Date/Time developed a geometric morphometric method to quantitatively characterize flower shape based on our field‐collected and crowdsourced images.
