Taxonomic notes:
This species has often been mistaken tor its nearest ally N. hexarrhena F. Muell. which differs in its leaves being 3-7 cm long, 0.8-1.8 cm broad; spikes quite thick, very woolly, up to 13 cm long, 1-1.5 cm diam.; ovary tomentose all over, with concealed glands at the top. A wider range of material shows that the difference between N. bracteosa and N. elliptica cannot be maintained as it seems to be due to age and seasonal growth.
