    [GB]
    Habit
    Annual. Culms erect; 3-40 cm long. Leaves mostly basal. Ligule an eciliate membrane. Leaf-blades filiform; involute; 0.5-5 cm long; 0.3-1 mm wide. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle; subtended by an inflated leaf-sheath; embraced at base by subtending leaf. Panicle open; ovate; dense; 1-12 cm long. Panicle branches terete; smooth. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; terete; 1-2 length of fertile spikelet.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets oblong to ovate; laterally compressed; 2 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets (florets arising at about the same level). Floret callus pubescent.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets oblong to ovate; laterally compressed; 2 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets (florets arising at about the same level). Floret callus pubescent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma; shiny; gaping. Lower glume ovate; 2 mm long; 1 length of upper glume; membranous; 1-keeled; keeled above; 1-3 -veined. Lower glume lateral veins absent, or obscure. Lower glume apex obtuse; mucronate. Upper glume ovate; 2 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; keeled above; 1-3 -veined. Upper glume lateral veins absent, or obscure. Upper glume apex obtuse; mucronate.
    Florets
    Fertile florets all alike, or with the lowest dissimilar. Lowest fertile lemma muticous, or awned. Fertile lemma ovate; laterally compressed; 1.5 mm long; cartilaginous; without keel; 5 -veined. Lemma lateral veins obscure. Lemma surface scaberulous; rough above. Lemma margins involute; covering most of palea. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn dorsal; arising 0.3-0.4 way up back of lemma; geniculate; 2-3 mm long overall; with twisted column. Palea cartilaginous; 2 -veined.
    Flowers
    Lodicules 2; lanceolate; membranous. Anthers 3. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged. Hilum punctiform. Endosperm farinose. Disseminule comprising a floret.
