The grass is growing to 500 - 600 mm high with a central stalk from which there are 10 - 60 mm racemes. The upper leaves are relatively short 70 mm long by 5 mm wide. The length of the inflorescence is about 150 mm. This grass grows on the transition from a wet Melaleuca woodland to drier Open Eucalyptus forest. As it was very windy on the day I couldn't easily take a photo in the field. Perhaps a Urachloa sp.
