Austrostipa scabra (Lindl.) S.W.L.Jacobs & J.Everett
Densely tufted, fine-leaved, perennial tussock with many innovation shoots; branching intravaginal. Leaf-sheath to 2 cm, with abundant retrorse short hairs, terminating in tuft of hairs to 1.5 mm subtending auricular lobes; auricular lobes symmetrical or asymmetrical to 0.5 mm. Ligule to 1.5 mm, shortly ciliate. Leaf-blade to 30 cm × 0.5 mm diam., inrolled, weakly acicular, abaxially very scabrid from short (0.25 mm) antrorse hairs and prickle-teeth in columns between ribs, adaxially with abundant short hairs; margins with antrorse prickle-teeth. Culm to 50 cm, pubescent below nodes, elsewhere glabrous. Panicle to 30 cm, sometimes subtended by long hairs or a bract; rachis, branches and pedicels short stiff hairy. Glumes subequal, purple below, tapering to hyaline awn-like processes, scabrid, > awn column; lower to 15 mm, 3-nerved, upper to 12 mm, 3-5-nerved. Lemma to 5 mm, clothed in white appressed hairs, less so above and becoming scabrid, lobes minute (0.25 mm); coma a few short hairs; awn to 65 mm, exceedingly falcate, ± 1-geniculate, column tightly twisted, short hairy, to 10-15 mm, arista to 50 mm. Palea internerve hairs long, apex glabrous. Callus to 1.5 mm, hairs to 2 mm. Lodicules 3, to 2 mm, ligulate. Anthers to 1.5 mm in cleistogamous, and to 3.5 mm in chasmogamous florets, penicillate. Fig. 5.

Ligule to 1.5 mm, shortly ciliate. Lamina to 30 cm × 0.5 mm diam., inrolled, weakly acicular, abaxially very scabrous from short (0.25 mm) antrorse hairs and prickle teeth in columns between nerves, adaxially with abundant short hairs, margins with antrorse prickle teeth. Culms to 50 cm, pubescent below nodes otherwise glabrous. Inflorescence to 30 cm, sometimes subtended by long hairs or a bract; rachis, branches and pedicels with shortstiff hairs. Glumes subequal, purple below, tapering to hyaline awn-like processes, scabrous with small prickle teeth; > awn column; lower to 15 mm, 3-nerved, upper to 12 mm, 3-5-nerved. Lemma to 5 mm, clothed in white appressed hairs, less so above and becoming scabrous, lobes minute (0.25 mm); coma a few short hairs; awn to 65 mm, exceedingly falcate, ± 1-geniculate, column tighdy twisted, and with short hairs, to 10-15 mm, arista to 50 mm.
