Perennial; culms ascending, often matted, up to about 1 m. high.. Leaf-blades flat, 5–20 cm. long, 3–11 mm. wide, the blades and sheaths tomentose with hairs which are often sticky and sometimes smelling strongly of linseed oil.. Panicle lanceolate to narrowly ovate, 10–30 cm. long, dense, often purplish; pedicels scaberulous (very rarely with a few long hairs).. Spikelets narrowly oblong, 1.5–2(–2.4) mm. long, glabrous or sometimes hairy; lower glume sometimes almost suppressed, but usually a little oblong scale 0.2–0.5 mm. long; upper glume straight on the back, prominently 7-nerved, these forming raised ribs, obtusely bilobed, with or without a mucro up to 0.5 mm. long; lower floret barren without a palea, the lemma 5-nerved, these forming ribs, acutely bilobed, with an awn up to 15 mm. long or sometimes awnless; upper lemma as long as the palea.. Fig. 124.
Perennial. Culms tufted, geniculately ascending, rooting at lower nodes, 50–150 cm tall. Leaf sheaths and blades densely tomentose with glandular hairs, slightly sticky with a strong smell; leaf blades linear, 5–20 × 0.5–1.5 cm. Panicle purplish, narrowly ovate, 10–20 cm; pedicels glabrous, scaberulous, rarely with a few hairs toward the apex. Spikelets narrowly ovate-oblong, 1.7–2.2 mm; lower glume ovate, 0.1–0.4 mm, veinless; upper glume prominently 7-veined, obtusely 2-lobed, awnless or with a mucro to 1 mm from the sinus; lower floret neuter without a palea, lemma similar to upper glume but narrower, prominently 5-veined, acutely 2-lobed, awnless or with a slender awn to 15 mm from the sinus; upper floret whitish, thinly cartilaginous, smooth, shining, slightly shorter than lower lemma. Fl. and fr. Jul–Oct. 2n = 36.
Tufted perennial 800-1 500 mm; densely hairy, strongly aromatic and sticky as hairs finely tubercled, exuding drops of viscid oil. Leaf blade 40-200 x 5-11 mm. Inflorescence narrowly ovate; pedicels glabrous, scabrous occasionally with 1-3 long hairs at apex. Spikelet 1.5-2.2(2.4) x 0.5 mm, narrowly ovate to narrowly oblong, glabrous, sometimes shortly hairy; lower glume 0.1-0.4 mm long; upper glume 7-nerved, obtusely bilobed, mucronate or awnless rarely with awn 0.5-9.0 mm long, usually glabrous; internode absent; upper glume and lower lemma deeply grooved between prominent veins; lower lemma 5-nerved, acutely bilobed, awnless or awn 5-14 mm long; lower palea absent; anthers 1.0-1.2 mm long.
Perennial, tufted, 1.5 m high. Leaf blades 40-200 mm long, 5-11 mm wide, leaves strongly aromatic and sticky, hairs finely tubercled, exuding drops of viscid oil. Spikelets 1.5-2.0 mm long, 0.5 mm wide, glabrous and sometimes shortly hairy; upper glume 7-nerved, often with awn 0-9 mm long; upper glume and lower lemma grooved between prominent veins; lower lemma awnless or awned, awn 5-14 mm long.
Inferior glume 0.1–0.4 mm. long, ovate, 0–1-nerved, inserted close to the superior; superior glume prominently 7-nerved, awnless or with a short mucro (rarely conspicuously awned), membranous, obtusely bilobed, glabrous, rarely hairy.
Inferior floret barren without a palea, its lemma prominently 5-nerved, acutely bilobed, equalling the superior glume but narrower, awnless or with an awn up to 14 mm. long.
