Densely tufted, robust perennial, 1.5-2.0 m high; rhizomatous; basal sheaths hairy; fresh shoots not aromatic. Leaf blade up to 600 x 3-8 mm; ligule an unfringed membrane. Inflorescence of paired racemes; enclosed by spatheoles 20-25 mm long, crowded into large, leafy, false panicle; peduncles 15-50 mm long; raceme pairs with 10-25 awns; raceme bases subequal, flattened, short-appendaged. Sessile spikelets 4-5 mm long, dorsiventrally compressed, densely long-hairy to shortly hairy, rarely glabrous. Florets 2; lower floret sterile, reduced to a lemma, awnless; upper floret bisexual, lemma less firm than glumes towards base, hyaline, 2-lobed, awns 8-20 mm long, hairy; callus cuneate, 1 mm long, tip visible on apex of internode. Pedicellate spikelets villous to hispidulous, rarely glabrous. Flowering time Nov.-May.
False panicle 20–50 cm long, narrow, fairly dense; spatheoles 2.5–5 cm long, narrowly lanceolate, glabrous or thinly hirsute (rarely the whole panicle copiously villous), becoming reddish-brown; peduncles 1.5–5 cm long, from half as long as to rather longer than the spatheole, pilose above with yellowish hairs; racemes 2–3 cm long, 10–25-awned per pair, usually exserted terminally, tardily deflexed; raceme-bases subequal, the superior 1–1.5 mm long, flattened, stiffly barbate, the apex with a scarious rim and usually produced into a definite oblong appendage up to 0.5 mm long.
Densely tufted, robust perennial 1500-2000 mm high; rhizomatous; basal sheaths hairy; culm 4-9 mm wide. Leaf blade to 600 x 3-8 mm. Spatheole 20-25 mm long; peduncle 15-50 mm long; raceme bases subequal, flattened, short-appendaged; raceme pairs with 10-25 awns. Sessile spikelet 4-5 mm long, densely long-hairy to shortly hairy, rarely glabrous; awn 8-20 mm long; callus 1 mm long, cuneate. Pedicellate spikelet 5-6 mm long, villous to hispidulous, rarely glabrous, muticous or awn up to 1.5 mm long; anther 1.6-2.5 mm long.
Perennial; up to 2 m high; robust; rhizomatous and densely tufted. Culms 4-9 mm in diameter. Leaf blades up to 600 x 3-8 mm; basal sheaths hairy. Flowers: in a complex; false panicle; raceme pairs with 10-15 awns; awns 8-20 mm long; raceme bases subequal; flattened; short-appendaged; sessile spikelets 4-5 mm long; densely long-hairy to shortly hairy; rarely glabrous; callus cuneate; 1 mm long; pedicellate spikelets villous to hispidulous; rarely glabrous; spatheoles 20-25 mm long; peduncles 15-50 mm long.
Robust perennial, rhizomatous and tufted (densely), up to 2 m high. Leaf blades up to 600 mm long, 3-8 mm wide. Culms 4-9 mm across; basal sheaths hairy. Spikelets (sessile) 4-5 mm long (densely long-hairy to shortly hairy, rarely glabrous, callus cuneate, 1 mm long). Spatheoles 20-25 mm long; peduncles 15-50 mm long; raceme pairs with 10-25 awns 8-20 mm long; raceme bases subequal, flattened, short-appendaged; pedicellate spikelets villous to hispidulous, rarely glabrous.
Sessile spikelets 4–5 mm long; callus c. 1 mm long, cuneate, subacute to narrowly obtuse at the apex; inferior glume oblong-lanceolate, yellowish-green to light brown or purple, densely villous to hispidulous, rarely glabrous; awn (1)8–20(28) mm long, the column pubescent with tawny hairs.
Basal leaf sheaths silky pubescent below, otherwise all sheaths glabrous; leaf laminas up to 60 cm × 3–8 mm, flat or inrolled and narrower, glabrous, usually stiff and glaucous with scaberulous nerves and harsh to the touch, sometimes soft and green.
Pedicelled spikelets 5–6 mm long, similar to the sessile spikelets in indumentum and colouring, muticous or with a short awn-point up to 1.5 mm long at the apex; callus scarcely developed; pedicel-tooth obscure.
Robust, densely caespitose perennial; culms up to 200 cm high (or more) and up to 4 mm in diameter at the base, simple or scantily branched.
Homogamous spikelets 5–7 mm long, a single pair at the base of the inferior raceme only, villous or rarely glabrous.
