A new species of Neurachne (Poaceae) from Western Australia

Neurachne annularis T.Macfarlane is described and illustrated with photographs and a distribution map. The new species forms Triodia-like hummocks and grows on and around banded ironstone ranges in the Yilgarn region of Western Australia where it is often dominant in the understorey. The species has the C₃ photosynthetic pathway and is diploid with n = 9, one of three species with that combination in a genus now of seven species. It is morphologically closest to N. tenuifolia S.T.Blake, from ranges in Central Australia.
