Analyses of DNA sequences from four genes and morphological data show that the members of the tropical forest tree family Icacinaceae do not have a common origin. Expand
The phylogenetic utility of chloroplast and nuclear DNA markers and the phylogeny of the Rubiaceae tribe Spermacoceae.
IT was, despite often raised cautions of its utility at higher taxonomic levels, shown to provide the highest number of parsimony informative characters, and in partitioned Bayesian analyses it yielded the fewest trees in the 95% credible set. Expand
Phylogeny of the Herbaceous Tribe Spermacoceae (Rubiaceae) Based on Plastid DNA Data1
This study is the first to address phylogenetic relationships within Spermacoceae from a tribal perspective and provides a phylogenetic hypothesis with broad sampling across the major lineages of Spermcoceae that can be used to guide future species-level and generic studies. Expand
The family Pennantiaceae and its relationships to Apiales
This thesis deals with evolutionary relationships within the asterids, a group of plants comprising about one-third of all flowering plants, and identifies two new families: Pennantiaceae and Stemonuraceae, which were formerly included in Icacinaceae. Expand
The wood anatomy of the polyphyletic Icacinaceae s.l., and their relationships within asterids
Maximum parsimony and Bayesian analyses using molecular data and combined anatomical-molecular data show that Icacinaceae s.str. Expand
Phylogeny of Hedyotis L. (Rubiaceae Spermacoceae) : Redefining a complex Asian-Pacific assemblage
Bayesian phylogenetic analyses of Hedyotis are presented using plastid and nuclear sequence data to resolve monophyletic lineages, to test former taxonomic hypotheses, and to revise the taxa within a well-supported evolutionary framework. Expand
Phyllopentas flava (Rubiaceae), a New Morphologically Heterodistylous and Functionally Dioecious Species from Madagascar
This plant is restricted to the Itremo region in southeastern Madagascar and is distinct morphologically from the other species of the genus by its pubescent, narrowly ovate to narrowly elliptic leaves, grey-whitish and thickly hairy midribs and secondary veins on the lower surfaces of leaves, and functionally dioecious and heterodistylous flowers. Expand
The systematics of Knoxieae (Rubiaceae)—molecular data and their taxonomic consequences
A molecular phylogeny of the Knoxieae group is presented and the morphological support for the resulting groups and the taxonomic consequences of the phylogeny are discussed. Expand
Evolution of the Australasian families Alseuosmiaceae, Argophyllaceae, and Phellinaceae
Based 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-Expand
