Characteristics

Annual. Culms loosely tufted, ascending, up to 100 cm tall, glabrous or pilose with long fine hairs below inflorescence. Leaf sheaths puberulous or glabrous; leaf blades linear, 10–30 × 0.6–1 cm, adaxial surface papillose-pilose, base subrounded, apex acuminate; ligule 1–2 mm. Inflorescence subdigitate, axis villous; racemes 3–8, 10–20 cm; spikelets ternate; rachis broadly winged, ca. 1 mm broad, midrib low, margins scabrous; pedicel tips hispid with 0.2–0.8 mm setae. Spikelets oblong-lanceolate or elliptic-lanceolate, 1.8–2.5 mm, pale grayish green, hairs clavate; lower glume absent; upper glume 2/3–3/4 as long as spikelet, narrower than spikelet, intervein spaces and margins appressed-pilose to hirsute; lower lemma as long as spikelet, 5-veined with a central group of 3 and 2 marginal veins, intervein spaces and margins hairy; upper lemma blackish brown at maturity, as long as spikelet. Anthers 0.4–0.8 mm. Fl. and fr. Jun–Sep. 2n = 36.

Loosely tufted annual, 200-600 mm high. Leaf blade 20-200 x 1-7 mm; ligule an unfringed membrane. Inflorescence in pairs or subdigitate on a short central axis, of 2-6 racemes; rachis triquetrous, broadly winged, glabrous, margins glabrous or scaberulous; pedicels with a corona of short hairs at apex; spikelets abaxial, in clusters of 2 or 3. Spikelets 2.5-2.7 mm long, oblong, dorsiventrally compressed; lower glume reduced to small cuff, obscure; upper glume 3/4 as long as spikelet, 3-nerved, clavate hairs between nerves; internode absent. Florets 2; lower floret sterile, lemma lanceolate, as long as spikelet, not deeply grooved, 5-nerved, covered with white clavate hairs; upper floret bisexual, lemma ± as long as spikelet, light to dark brown or purplish black margins flat and covering most of palea. Flowering time Nov.-May.
Loosely tufted annual 200-600 mm high. Leaf blade 20-200 x 1-7 mm.

Spikelet 1.5-2.7 mm long, oblong, densely hairy, hairs clavate; lower glume reduced to small obscure cuff or absent; upper glume 2/3 as long as spikelet, 3-nerved, clavate hairs between nerves; internode absent; lower lemma as long as spikelet, not deeply grooved, 5-nerved, nerves smooth, hairs clavate-tipped; upper lemma as long as spikelet, dark brown or purplish black; anthers 1.0-1.4 mm long.
