Gahnia aspera




Gahnia, which grows 15-65 cm tall, has long, grass-like leaves with sharp, saw-edged margins. The attractive flower spike is dark brown to black, and after flowering bears shiny, dark, red-brown seeds.

This sedge is a widespread plant in the direr parts of rainforest, open forest and woodland. It is found on the coast, tablelands, western slopes and plains of New South Wales and also in Queensland, Malaysia, Indonesia and Polynesia.


  • The seeds are pounded to produce flour.
