CLASSIFICATION OF AUSTRALIAN GRASSES

Ideas on the classification of grasses are in a constant state of flux. Current work in this field is being conducted in many centres as can be seen from the proceedings the symposia on the classification and evolution of grasses from 1986 onwards (Soderstrom, Hilu, Campbell and Barkworth 1987; Jacobs and Everett 2000; J.T.Columbus et al 2007; Seberg et al. 2010).

The classification presented here is in contrast to those I proposed earlier (Simon 1983, 1991; Simon in Sharp & Simon 2002) with regard to the number of subfamilies recognised and the composition and tribes within the subfamilies. The subfamilies recognised are a reflection of the prevailing consensus of the Grass Phylogeny Working Group recently published in New Phytologist (GPWG II 2011). This classification builds on the first classification of the GPWG published in the Annals of the Missouri Botanical Garden (GPWG 2001).

The sequence of the genera within each subfamily is according to that being followed by the grass volumes for the Flora of Australia, and reflect the relationships between genera, so that closely related genera are near each other.

The taxonomic groupings of genera are arranged in a hierarchy of two ranks:

Subfamily (with suffix -oideae) and Tribe (with suffix -eae). The supertribe and subtribe ranks used in the 1993 classification are not used here, as they do not reflect phylogenetic lineages as currently understood.
