Gahnia aspera

Gahnia aspera known as the rough saw-sedge or round sawsedge is a tussock forming perennial plant, often seen in moist situations. The long strap like leaves grow to 80 cm long. Originally described by botanist Robert Brown as Lampocarya aspera in his 1810 work Prodromus Florae Novae Hollandiae, it was placed in its current genus by German botanist Curt Polycarp Joachim Sprengel in 1825. Its specific name aspera is the Latin adjective asper "rough". Gahnia aspera grows as a strappy tussock 50–100 cm (20–39 in) high by 50–150 cm (20–59 in) across, with leaves to 80 cm (31 in) long. The underside of the leaves and leaf edges are sharp and can easily cut human skin. The creamy flowers grow in spikes from the centre of the plant and appear from October to January. They are followed by shiny red or red-brown round nuts, which measure 4.5 to 6.0 mm long, 2.5 to 4.0 mm in diameter. Two subspecies are accepted.
