Dense rather shining tussock, 30-100 cm tall, sometimes hanging down steep banks and up to 2 m long, with light brownish-green sometimes glaucous leaves smooth to the touch; new shoots intravaginal; laminae persistent. Sheaths pale green, later creamy brown, shining, nerves thickened but not very prominent abaxially, internerves ± membranous, glabrous and smooth, or very minutely scabrous throughout; ligule c. 0.5 mm long, truncate, short-ciliate across top, minutely ciliate abaxially; lamina (10)-20-60cm × c. 1-1.5-(2.5) mm, folded or ± flat, coriaceous, abaxially smooth, somewhat ridged with keel not very prominent, adaxially closely short-ciliate throughout, margins inrolled, scabrous, midnerve scabrous near acicular, often stiff-pungent tip. Culms (10)-20-50- (70) cm tall, ± equalling or shorter than leaves, smooth to scabrous below panicle. Panicle (5)—10— 20-(25) cm long, open, branchlets slender, ± erect to spreading, sparsely to very closely scabrous, naked below, the numerous spikelets borne along shorter secondary branchlets. Spikelets (3.5)-6- 9 mm long, (2)-3-5-flowered, light green to later light brown. Glumes subequal, (2)-3.5-5-(6) mm long, midnerve with sparse teeth in upper half, membranous margins with scattered fine teeth above, or almost throughout, elsewhere sparsely short-scabrous to smooth, tip acute to subacuminate; lower glume 1-(3)-nerved, narrow-lanceolate, upper 3-(5)-nerved, elliptic-lanceolate. Lemma 3- 5-(6) mm long, 5-nerved, elliptic-oblong, obtuse, internerves minutely short-scabrous throughout, midnerve with long crimped hairs to half-way, scabrous above, outer lateral nerves with crimped hair near base, membranous margins sparsely minutely scabrous. Palea (2)-3-4 mm long, short-scabrous to ciliate-dentate between densely ciliate-dentate keels, short-scabrous on margins. Lodicules c. 0.5 mm long, occasionally hair-tipped. Callus with tuft of crimped hairs. Rachilla c. 1 mm long, scabrous or with some longer hairs. Anthers (1)- 2-3 mm long. Caryopsis c. 1 × 0.5 mm. 2n = 84 (as P. laevis R. Br.). Endemic

Dense rather shining tussock, 30-100 cm, sometimes hanging down steep banks and up to 2 m, with light brownish green sometimes glaucous leaves smooth to the touch; branching intravaginal; leaf-blades persistent. Leaf-sheath pale green, later creamy brown, shining, ± membranous, smooth, or very minutely scabrid throughout, ribs inconspicuous. Ligule c. 0.5 mm, truncate, short-ciliate, abaxially minutely hairy. Leaf-blade (10)-20-60 cm ×c. 1-1.5-(2.5) mm, folded or ± flat, coriaceous, abaxially glabrous, midrib and lateral ribs not very prominent, adaxially closely minutely pubescent throughout; margins inrolled, scabrid, midnerve scabrid near acicular, often pungent tip. Culm (10)-20-50-(70) cm, ≤ leaves, internodes smooth to scabrid below panicle. Panicle (5)-10-20-(25) cm, open; branches slender, ± erect to spreading, sparsely to very closely scabrid, naked below, spikelets many on shorter secondary branchlets. Spikelets (3.5)-6-9 mm, (2)-3-5-flowered, light green to later light brown. Glumes subequal, (2)-3.5-5-(6) mm, acute to subacuminate, sparsely minutely scabrid to smooth, midnerve with sparse prickle-teeth in upper ½; lower 1-(3)-nerved, narrow-lanceolate, upper 3-(5)-nerved, elliptic-lanceolate; margins membranous with scattered fine prickle-teeth above or almost throughout. Lemma 3-5-(6) mm, 5-nerved, elliptic-oblong, obtuse, minutely scabrid, midnerve with long crinkled hairs in lower ½, scabrid above, outer lateral nerves with crinkled hairs near base; margins membranous, sparsely minutely scabrid. Palea (2)-3-4 mm, keels densely ciliate-scabrid, interkeel minutely scabrid to pubescent-scabrid, flanks short-scabrid. Callus with tuft of crinkled hairs. Rachilla c. 1 mm, scabrid or with occasional hairs. Lodicules c. 0.5 mm, occasionally hair-tipped. Anthers (1)-2-3 mm. Caryopsis c. 1 × 0.5 mm. 2n= 84. Plate 7D.
