Danthonioideae. --The subfamily Danthonioideae has only been recognised as being separate from the Arundinoideae for a relatively short time (GPWG, 2001). A historical perspective on the subfamily (Linder & Barker 2005) shows how the composition of the subfamily has progressed from its early traditional admixture with the arundinoids to the recognition of a separate subfamily on phylogenetic principles based on molecular (Barker et al. 1995) and anatomical (Verboom et al.1994) data.
