Light bluish green or rarely pale yellow-green perennial tufts, (2.5)-10-50-(65) cm, with stiff culms and leaves, or with finer and less rigid leaves; branching intravaginal. Leaf-sheaths smooth, submembranous to subcoriaceous, + distinctly nerved, light brownish to purplish; ligule 0.7— 1.5—(2) mm, smooth, rounded to truncate, or + tapered at centre and acute; leaf-blades 1-12 cm, involute, c. 0.5 mm diam. in rolled state, rigid and erect, or finer and softer, abaxially smooth, adaxially sparsely scabrous on nerves, or sometimes densely scabrous throughout, margins scabrous, narrowed to a fine acute tip. Culms (2)-5-20-(40) cm, enclosed by uppermost leaf-sheaths at flowering, later visible, smooth, erect. Panicle (2}-4.5-14.5-(20) × 0.2-5.5 cm, at first narrow-linear, racemose above, with few, erect, usually scabrous branches below, later more open with ± spreading branches bare at base. Spikelets 3.5—9- (10.5) mm, 2—10-flowered, narrow, almost terete, light green to purplish. Glumes often quite unequal, elliptic-oblong, margins and sometimes midnerve minutely ciliate near tip; lower glume (0.6)—0.8— 2.3 mm, 1-nerved, subacute to subobtuse; upper glume (1.3)—2—3.5 mm, 3-nerved, subobtuse to obtuse. Lemma (2)-2.5—3-(4) mm, 5-nerved, broadelliptic, with very minute hairs at base not usually visible at × 10, and occasionally a few minute hairs on nerves near base, midnerve usually not quite reaching finely ciliate, obtuse tip. Palea slightly < lemma, bifid, keels scabrous in upper 2/3. Rachilla 0.5-1 mm. Anthers 0.4-1 mm. Caryopsis 1-1.8 × 0.4-0.7 mm. Also indigenous to Australia.

Light bluish green or rarely pale yellow-green perennial tufts, (2.5)-10-50-(65) cm, with stiff culms and leaves, or with finer and less rigid leaves; branching intravaginal. Leaf-sheath glabrous, submembranous to subcoriaceous, ± distinctly ribbed, light brownish to purplish. Ligule 0.7-1.5-(2) mm, glabrous, rounded to truncate, or ± tapered centrally and acute. Leaf-blade 1-12 cm ×c. 0.5 mm diam., involute, rigid and erect, or finer and softer, abaxially glabrous, adaxially sparsely scabrid on ribs, or sometimes densely scabrid throughout; margins scabrid, narrowed to fine acute tip. Culm (2)-5-20-(40) cm, erect, hidden by uppermost leaf-sheath at flowering, later visible, internodes glabrous. Panicle (2)-4.5-14.5-(20) × 0.2-5.5 cm, at first narrow-linear, racemose above, with few, erect, usually scabrid branches below, later more open with ± spreading branches naked below. Spikelets 3.5-9-(10.5) mm, 2-10-flowered, narrow, almost terete, light green to purplish. Glumes often quite unequal, elliptic-oblong, margins and sometimes midnerve minutely ciliate near apex; lower (0.6)-0.8-2.3 mm, 1-nerved, subacute to subobtuse, upper (1.3)-2-3.5 mm, 3-nerved, subobtuse to obtuse. Lemma (2)-2.5-3-(4) mm, 5-nerved, broad-elliptic, with very minute hairs at base not usually visible at ×10, and occasionally a few minute hairs on nerves near base, midnerve usually not quite reaching finely ciliate, obtuse apex. Palea ≤ lemma, apex bifid, keels scabrid in upper ⅔. Rachilla 0.5-1 mm. Anthers 0.4-1 mm. Caryopsis 1-1.8 × 0.4-0.7 mm.
