Plants perennial, loosely tufted, not rhizomatous, not sotoloniferous.
Culms 10-70 cm tall; lowest internode 0.5-2.2 mm thick.
Leaf blades 0.5-3.5 mm wide, flat to loosely involute.
Inflorescence spikelike, 1.5-13 cm long; rachis tough, usually prolonged beyond the base of the distal spikelet up to 3.5 mm, outer surface usually conspicuously hairy; lowest internode 3-12 mm long; middle internodes 2-7 mm long; disarticulation below the glumes.
Spikelets solitary, tangential to and usually strongly divergent or reflexed, sometimes ascending, 7.5-19 mm long, with 3-9 florets, usually on pedicels up to 1 mm long, sometimes not pedicellate.
Glumes often strongly divergent from the rachilla, 5-9 mm long, stiff, narrowly lanceolate, mostly glabrous and smooth, scabrous on the midvein, at least distally, tip narrowly acute or shortly awned.Lemmas 4.8-11 mm long, glabrous, awned, awns to 4 mm, straight. Paleas from 3/4 as long as to equaling the lemmas, keels with widely spaced, long, coarse teeth, converging to a narrow tip, often extending beyond the intercostal region. Lodicules ??. Anthers 1-6 mm long.
There are five species, one in New Guinea, one in New Zealand, and three in Australia.
