  • Description: <jats:p> Triodia bunicola (S.W.L.Jacobs) Lazarides and T. scariosa N.T.Burb. (Poaceae: Chloridoideae) were analysed to test their status as different species. Thirty-one morphological characters were scored for multivariate analysis for both species. Nuclear (ITS) and chloroplast (rpl32–trnL) DNA data were analysed cladistically for 18 species of Triodia, with a focus on species from southern Australia to look at broader geographic patterns. Cladistic analysis and morphological ordination analysis indicated that T. bunicola should be regarded as a synonym of T. scariosa. DNA evidence also suggests that there is geographic partitioning for southern Australian species of Triodia. </jats:p>
