    Habit
    Loosely caespitose annual; culms up to 40(70) cm tall, erect or geniculately ascending, often branched from the lower nodes; leaf laminas (1.5)2–12(15) cm × 1–4 mm, flat or involute, tapering to a fine point.
    Inflorescences
    Inflorescence (3.5)10–20(25) cm long; racemes 0.8–2 cm long, usually spreading, sometimes ascending, rarely reclining.
    Spikelets
    Spikelets up to 8 mm long, 3–6-flowered (rarely more), oblong to elliptic; rhachilla internodes terete, hairy towards the apex, rarely only scabrid; glumes lanceolate, the inferior (1.2)1.6–2.3(2.6) mm long, the superior (2.4)2.6–3.6 mm long; lemmas 3.2–5.6 mm long, elliptic-oblong to ovate-oblong, drawn out at the apex into a slightly recurved awn.
    [GB]
    Habit
    Annual; caespitose; clumped densely. Culms decumbent; 13-42 cm long. Culm-internodes distally pilose. Leaf-sheaths pilose; with tubercle-based hairs. Ligule a fringe of hairs. Leaf-blades 6-18 cm long; 3-6 mm wide. Leaf-blade surface pilose; with tubercle-based hairs.
    Inflorescences
    Inflorescence composed of racemes. Racemes numerous; borne along a central axis; ascending; unilateral; 2-5 cm long. Central inflorescence axis 8-15 cm long. Rhachis deciduous from axis; angular. Spikelet packing broadside to rhachis; crowded. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels oblong; 0.8-1.6 mm long.
    Spikelets
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent; hairy at tip.
    Fertile
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent; hairy at tip.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.2-2.4 mm long; 0.5-0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex attenuate. Upper glume lanceolate; 2.4-3.2 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex attenuate.
    Florets
    Fertile florets decreasing in size upwards. Fertile lemma lanceolate; 2-3 mm long; membranous; keeled; 3 -veined. Lemma midvein scaberulous. Lemma surface asperulous. Lemma apex attenuate; awned; 1 -awned. Principal lemma awn 1-2 mm long overall. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy.
    Fruits
    Caryopsis with adherent pericarp.
