Classification, origin, and diversification of the New Zealand hebes (Scrophulariaceae)
The New Zealand hebes (Scrophulariaceae) are members of a large Southern Hemisphere clade nested within Veronica. Analysis of ITS and rbcL sequences suggests that the New Zealand species are derived… Expand

The phylogeny of the Asteridae sensu lato based on chloroplast ndhF gene sequences.
A phylogenetic study of Asteridae sensu lato was conducted based on chloroplast ndhF gene sequences for 116 ingroup and 13 outgroup species. Prior molecular studies based on rbcL sequences identified… Expand

Classification, origins, and patterns of diversification in New ZealandCarmichaelinae (Fabaceae).
Analysis of ITS sequences provides support for a clade that includes Carmichaelia, Clianthus, Montigena, and Swainsona. We provide a node-based definition and recommend that this clade be called… Expand

Evolution and biogeography of Pleurophyllum (Astereae, Asteraceae), a small genus of megaherbs endemic to the subantarctic islands.
PREMISE OF THE STUDY The abundance of fossils in Antarctica suggests this continent was a center of diversification and a corridor for migration for many austral plant groups until the late Tertiary… Expand

Patterns of diversification in New Zealand Stylidiaceae.
Phylogenetic analysis of ITS and rbcL sequences show that New Zealand Stylidiaceae fall into two distinct lineages differing in species richness. Each lineage represents a unique dispersal event to… Expand

Systematics and ecology of the Australasian genus Empodisma (Restionaceae) and description of a new species from peatlands in northern New Zealand
Abstract The genus Empodisma comprises two species that are ecologically important in wetland habitats. Empodisma gracillimum is restricted to south-western Australia, whereas Empodisma minus is… Expand
