    [GB]
    Habit
    Annual; caespitose. Culms 30-100 cm long. Ligule a fringe of hairs. Leaf-blades 3-20 cm long; 2-12 mm wide.
    Inflorescences
    Inflorescence composed of racemes. Racemes 2-7; borne along a central axis; unilateral; 2-6 cm long. Central inflorescence axis 1-7 cm long. Rhachis angular; setose on margins. Rhachis hairs dark brown; 3-7 mm long. Spikelet packing abaxial; regular; 3-4 -rowed. Spikelets pectinate; solitary, or in pairs. Fertile spikelets sessile and pedicelled. Pedicels setose.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; compressed strongly; plano-convex; acuminate; 3.5-5.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; compressed strongly; plano-convex; acuminate; 3.5-5.5 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.25-0.5 length of spikelet; membranous; without keels; 3-5 -veined. Lower glume surface glabrous, or pilose; with tubercle-based hairs. Lower glume apex acute, or acuminate. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface glabrous, or pubescent. Upper glume margins setose. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 5-7 -veined; setose; hairy on veins; bearing dark brown hairs; acute. Fertile lemma oblong; dorsally compressed; 3-4 mm long; indurate; without keel. Lemma surface papillose. Lemma margins involute. Lemma apex obtuse; mucronate. Principal lemma awn 0.5 mm long overall. Palea indurate.
