    [GB]
    Habit
    Annual; caespitose. Culms decumbent; 17-68 cm long. Ligule an eciliate membrane; 1 mm long. Leaf-blades 6-16 cm long; 2.5-4 mm wide. Leaf-blade surface smooth; glabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; 6-12 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear; scaberulous.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5.4-6.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 5.4-6.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; parallel to lemmas. Lower glume lanceolate, or elliptic; 2.8-5 mm long; 0.7-0.9 length of upper glume; membranous; without keels; 3 -veined. Lower glume lateral veins ribbed. Lower glume apex acute. Upper glume elliptic, or oblong; 3.6-5.7 mm long; 1.2-1.3 length of adjacent fertile lemma; membranous; without keels; 3-4 -veined. Upper glume lateral veins ribbed. Upper glume apex acute.
    Florets
    Fertile lemma ovate; 3-4.3 mm long; membranous; without keel; 3 -veined. Lemma lateral veins thickened; ribbed; close to margins. Lemma surface asperulous. Lemma apex truncate, or obtuse; muticous, or mucronate. Palea 0.9-1 length of lemma; 2 -veined. Palea keels scaberulous; eciliate. Palea surface asperulous. Apical sterile florets resembling fertile though underdeveloped.
    Fruits
    Caryopsis with free soft pericarp; oblong; flattened; concavo-convex; 1.75-2 mm long; rugose (obscurely), or granular. Embryo 0.6-0.7 length of caryopsis.

    Habit
    Slender tufted annual; culms 17–68 cm. high, geniculately ascending.
    Leaves
    Leaf-blades linear, 6–16 cm. long, 2.5–4 mm. wide, soft, smooth and glabrous, tapering to a fine tip; ligule ± 1 mm. long.
    Inflorescences
    Inflorescence an ovate open panicle 6–12 cm. long, the branches sometimes simple and reduced to racemes.
    Spikelets
    Spikelets 5–10-flowered, broadly elliptic, 5.4–6.8 mm. long; glumes slightly unequal, rounded on the back, subacute and sometimes mucronulate, shorter than or slightly exceeding the lowermost lemmas, the lower 3-nerved, lanceolate to elliptic-oblong, 2.8–5 mm. long, the upper 3–4-nerved, elliptic-oblong, 3.6–5.7 mm. long; lemmas prominently 3-nerved with the lateral nerves as long as the lemma, broadly elliptic, 3–4.3 mm. long, membranous, densely asperulous, the tip broadly rounded to truncate and often mucronulate; palea densely asperulous like the lemma.
    Fruits
    Grain broadly elliptic, 1.75–2 mm. long, strongly dorso-ventrally flattened, shallowly concave on the hilar side, finely rugulose.
