Description and photo (pages 95-96) and line drawing of seed and husks (Fig. 20e page 94) in G.M. Cunningham, WE Mulham, PL Milthorpe and J H Leigh (1981 and later printings) Plants of Western New South Wales. The description of the flowerhead 'becoming fluffy and grey, gradually turning black at maturity' is incorrect.
