Characteristics

Spikelets 8–14(17) × 3.5–6 mm, oblong to broadly oblong, strongly laterally compressed, 12–30-flowered, the florets disarticulating from the apex downwards, the rhachilla fragile (less so in the lower part); glumes subequal, 2.5–3.3 mm long, reaching to 2/3 or 3/4 the way along the adjacent lemmas, keeled, ovate-lanceolate in profile, scabrid on the keel, ciliolate on the margins, acute at the apex; lemmas 3.2–5 mm long, keeled, ovate-lanceolate in profile, firmly membranous with distinct lateral nerves, slightly diverging from the rhachilla, those in opposite rows imbricate and concealing the rhachilla, greenish or yellowish, suffused with purple or at least with purple apex, smooth on the keel and nerves, faintly asperulous on the flanks near the margins, acuminate to shortly awned at the apex; palea glabrous on the flanks, the keels slender, wingless, scabrid; anthers 3, 1–1.5 mm long.
More
Caespitose annual; culms up to 75 cm tall, erect or ascending, branched or unbranched, glabrous at the nodes, the internodes with scattered crateriform glands and with a ring of glands below the nodes; leaf sheaths with scattered crateriform glands; ligule a line of hairs; leaf laminas 2.5–8(15) cm × 2.5–4.5(8) mm, broadly linear, flat or involute, pubescent above with additional long hairs, with crateriform glands along the margins and on the nerves beneath (especially or only on the midnerve), glaucous, stiff and pungent.
Panicle 7–15 cm long, oblong-elliptic to ovate, the spikelets evenly distributed on stiff pedicels 1–2 mm long, the primary branches stiffly ascending or spreading, loosely racemose, not in whorls, terminating in a fertile spikelet, shortly pilose in the axils, with crateriform glands along the main axis, branches and pedicels, these sometimes numerous.
Caryopsis c. 0.4 mm long, broadly elliptic to subrotund.
