Observations of growth habit and habitats and statistical analysis of detailed morphological measurements on specimens of Agrostis billardierei R. Br. and some closely related taxa has resulted in a re-evaluation of the rank and status of some of them.New combinations are made for Agrostis billardierei var.robusta Vickery, A. billardierei var.collicola D. Morris, A. billardierei var.filifolia Vickery and A. aemula var.setifolia Vickery.The new names for these taxa are A. robusta, A. collicola, A. punicea war.filifolia and A. punicea var.punicea respectively.Agrostis billardierei var.tenuiseta D. Morris is confirmed as a good taxon.
