    Habit
    Tufted perennial; culms wiry, 50–150 cm. high, 1–3 mm. diameter at the base.
    Leaves
    Leaf-blades narrow, often almost filiform, 6–20 cm. long, 1–4 mm. wide.
    Inflorescences
    Panicles axillary, slender, 2–4 cm. long, gathered into a scanty false panicle; rhachis with rounded ribs and distinct peduncle-stumps, usually scaberulous; involucre reduced to a single bristle beneath each spikelet; bristle glabrous, 6–36 mm. long.

    [GB]
    Habit
    Perennial. Culms erect; slender; 50-150 cm long; 1-3 mm diam.; wiry. Ligule a ciliate membrane. Leaf-blades filiform, or linear; 6-20 cm long; 1-4 mm wide; firm.
    Inflorescences
    Synflorescence compound; scanty. Inflorescence a panicle; terminal and axillary. Panicle spiciform; linear; 2-4 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis scaberulous; glabrous. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; base obtuse. Involucral bristles deciduous with the fertile spikelets; in one whorl; 1 in principal whorl; 6-36 mm long; terete; flexible; glabrous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; acuminate; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; acuminate; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate.
    Glume
    Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume oblong; 0.4-0.7 mm long; 0.5-0.75 length of upper glume; 0.1-0.15 length of spikelet; hyaline; pallid; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume oblong; 0.4-0.7 mm long; 0.1-0.15 length of spikelet; hyaline; pallid; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; scaberulous; acuminate. Fertile lemma elliptic; 3-4 mm long; cartilaginous; without keel; 5 -veined. Lemma surface scaberulous. Lemma margins flat. Lemma apex acute. Palea cartilaginous.
