    [GB]
    Habit
    Perennial; caespitose. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms erect; 12-60 cm long. Ligule a fringe of hairs. Leaf-blades filiform, or linear; convolute; 5-12 cm long; 1-2 mm wide.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear, or lanceolate, or ovate; 5-16 cm long; contracted about primary branches. Primary panicle branches naked below. Panicle branches glabrous in axils. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 2-3 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 2-3 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; shorter than spikelet. Lower glume oblong, or ovate; 0.8-1.4 mm long; 0.7-0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.1-1.2 mm long; 0.5-0.75 length of adjacent fertile lemma; membranous; dark green, or grey; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume surface smooth, or asperulous. Upper glume apex acute.
    Florets
    Fertile lemma ovate; 2-3 mm long; membranous; dark green, or grey; without keel; 1 -veined. Lemma surface smooth, or scaberulous. Lemma apex acute. Palea 2 -veined. Palea keels approximate.

    Inflorescences
    Panicle 5–11 cm long, linear to narrowly ovate or ovate; primary branches not in whorls, smooth or scabridulous, eglandular, the spikelets subsecund loosely contracted about the primary branches, these bare of spikelets or branchlets in the lower 1/4–1/3.Spikelets 1.8–2.6 mm long, grey-green to very dark green; inferior glume 1/3–1/2 the length of the spikelet, oblong to narrowly ovate, hyaline, nerveless, glabrous, raggedly obtuse to acute at the apex; superior glume (1/2)3/5–3/4 the length of the spikelet, narrowly ovate, hyaline, 1-nerved, glabrous, acute at the apex; lemma as long as the spikelet, narrowly ovate, acute; anthers 3, 0.8–1.3 mm long.
    Fruits
    Grain 1–1.2 mm long, elliptic, truncate at the top.
