Austrostipa, speargrass, is a genus of grasses mostly endemic to Australasia. One species, A. variabilis, is found in both Australia and southern Africa.

Characters (from New South Wales Flora Online): Perennials (rarely annuals) of various habit. Auricles often present, sometimes one-sided, grading into an usually membranous ligule. Blade rolled or folded in bud, convolute, terete or flat, usually scabrous or hairy. Inflorescence an open or contracted panicle, axis persistent or falling as a whole. Spikelets borne singly, pedicellate, disarticulating above the glumes; 1 bisexual floret. Glumes equal or unequal. 1–5-nerved, longer than the floret; a long or short bearded callus below each floret. Lemma terete, hardened, with convolute or involute margins enclosing the palea, usually 5-nerved, with or without 1–2 minute lobes, awned from the tip or between the lobes; awn with once or twice geniculate twisted column and a straight or curved bristle. Palea membranous. 0–2-nerved, longer or shorter than the lemma. Lodicles 3 or 2.
