Panicle lanceolate to broadly ovate, 10–30 cm. long; primary branches stout, usually with secondary branchlets but sometimes almost raceme-like, the spikelets on short pedicels 1–5 mm. long.. Spikelets 6–28(–47)-flowered, narrowly ovate to suborbicular, 6–16(–23) mm. long, 3–10 mm. wide, strongly flattened, green tinged with brownish purple, disarticulating below the glumes at maturity and falling entire; glumes lanceolate in side view, subequal, 2–4 mm. long; lemma narrowly ovate in side view, 3–4.5 mm. long, strongly keeled, the keel scaberulous, narrowly obtuse; palea 2-nerved, the nerves thickened, cartilaginous, and bearing a hyaline minutely ciliolate wing; anthers 3, 2 mm. long.. Caryopsis ellipsoid, 1–1.5 mm. long.. Fig. 61/9, p. 193.
Spikelets 6–16(23) × 3–10 mm, narrowly ovate to suborbicular, strongly laterally compressed, 6–28(47)-flowered, disarticulating below the glumes and falling entire; glumes subequal, 2–4 mm long, reaching to just beyond the middle of the adjacent lemmas, keeled, lanceolate in profile, glabrous, subacute at the apex; lemmas 3–4.5 mm long, keeled, narrowly ovate in profile, subcoriaceous with conspicuous lateral nerves, diverging from the rhachilla at c. 45° but those in opposite rows imbricate and concealing the rhachilla, green tinged with brownish-purple, scaberulous on the keel, narrowly obtuse at the apex; palea glabrous on the flanks, the keels thickened and cartilaginous, winged throughout, gibbously so below, the wing protruding from the sides of the lemma, the wing margin entire and minutely ciliolate; anthers 3, 1.5–2.5 mm long.
