Abstract
Although the Australasian grass genus Austrostipa is species rich, abundant and ecologically significant, the subgeneric classification of its 62 species has not been comprehensively tested with molecular data. We used three molecular markers from 51 species to determine a phylogeny of the genus and found strong support for the following seven of the existing subgenera: Falcatae, Austrostipa, Aulax, Lobatae, Bambusina, Lancea and Longiaristatae. The molecular data do not support Tuberculatae and Eremophilae, which could be combined with subgenus Austrostipa. The data are equivocal or insufficient regarding monophyly of Ceres, Arbuscula, Petaurista and Lanterna. Data from the nuclear internal..
