Phylogeny and phylogeography of Zieria (Rutaceae)

Abstract

Zieria (Anthophyta: Rutaceae) is a predominately Australian genus of shrubs and small trees, consisting of 59 Australian species and one species endemic to New Caledonia. Although there has been considerable taxonomic revision of this genus in recent decades, largely based on morphology, a comprehensive molecular phylogenetic study that would include as many currently-recognised taxa as possible was clearly needed. Using five chloroplast markers (rpl32–trnL, trnL–F, trnQ–5'rps16, trnS–G and 3'trnV– ndhC) and two nuclear DNA markers (ITS and ETS) this study undertook phylogenetic analyses in order to understand relationships, evolutionary processes and taxonomic issues in Zieria, and to inter..
