Abstract
The Australasian region contains a significant proportion of worldwide Poa diversity, but the evolutionary relationships of taxa from this region are incompletely understood. Most Australasian species have been placed in a monophyletic Poa subgenus, Poa supersection Homalopoa section Brizoides clade, but with limited resolution of relationships. In this study, phylogenetic relationships were reconstructed for Australasian Poa, using three plastid (rbcL and matK genes and the rpl32-trnL intergenic spacer) and two nuclear [internal/external transcribed spacer (ITS/ETS)] markers. Seventy-five Poa spp. were represented (including 42 Australian, nine New Guinean, nine New Zealand and three Austra..
