Description: Tufted perennials with short rhizomes; culms erect or geniculate at the base, slender, smooth.
Leaves with ligule a short fringe of hairs; blade narrow, stiff, pointed, convolute.
Inflorescence a short, spike-like panicle.
Spikelets solitary on short pedicels, rachilla disarticulating above the glumes, 1 bisexual floret, lower spikelets sometimes sterile. Glumes subequal, firm, 3-nerved. Lemmas close around the palea, hairy on the 3 nerves, deeply divided into 3 lobes which taper into scabrid or ciliate awn-like bristles, lobes longer than the body of the lemma and with the thin margins often forming delicate lateral lobes. Palea subequal to the lemma, deeply 2-lobed, the lobes tapering into awn-like bristles.
Distribution and occurrence: World: 7 species, endemic Australia. Australia: all mainland States.
