Lepidosperma avium, commonly named the central Australian rapier-sedge and the desert rush, is a rare species of sedge found in the Everard Ranges of remote northern South Australia and neighbouring parts of the Northern Territory.
Lepidosperma avium forms clumps, between tall. The stems are stiff, hairless, and smooth, less than a centimetre thick, with small lines and grooves all over the surface. ==Ecology==
