Abstract
A phylogeny of Dianella is presented based on Bayesian and maximum parsimony analyses of a combined molecular data set using three chloroplast markers (trnQUUG–5'rps16, 3'rps16–5'trnK(UUU) and rpl14–rps8–infA–rpl36) and two nuclear markers (ITS and ETS). Accessions included most Dianella species, including all species from Australia, the centre of diversity for the genus, and related outgroup genera Eccremis, Stypandra, Thelionema and Herpolirion. The phylogeny showed Stypandra sister to Herpolirion + Thelionema, and confirmed the monophyly of Dianella. Within Dianella, a number of clades were resolved that revealed biogeographic relationships. Accessions from south-western Australia (extend..
