    Habit
    Annual. Culms decumbent; 50 cm long; 1-2.3 mm diam.; rooting from lower nodes. Culm-nodes brown; glabrous. Leaf-sheaths 3.5-6 cm long; hirsute; with tubercle-based hairs. Ligule an eciliate membrane; 2-2.7 mm long; erose; truncate. Leaf-blades lanceolate; 6.3-8.5 cm long; 5.5-7 mm wide; chartaceous. Leaf-blade surface scabrous; rough on both sides. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Peduncle 35 cm long; glabrous. Racemes 4-5(-8); borne along a central axis; closely spaced; appressed; unilateral; 3-4 cm long. Central inflorescence axis (1-)3-4.5 cm long. Rhachis narrowly winged; angular; 0.6-1 mm wide; scabrous on margins. Spikelet packing crowded. Spikelets in pairs. Fertile spikelets sessile and pedicelled. Pedicels 0.3-1 mm long; scabrous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 4.5-5 mm long; 1.2-1.3 mm wide; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 4.5-5 mm long; 1.2-1.3 mm wide; falling entire.
    Glume
    Glumes dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume linear, or lanceolate; (0.5-)1-1.5(-2.5) mm long; 0.25 length of spikelet; membranous; without keels; 1-3 -veined. Lower glume lateral veins absent, or obscure. Lower glume surface glabrous, or pilose. Lower glume apex acuminate. Upper glume lanceolate; 3-3.5 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface pilose; hairy between veins. Upper glume margins ciliate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 7 -veined; prominently veined; with unevenly spaced veins; pilose; hairy between veins but central interspaces glabrous; acute. Fertile lemma lanceolate; 4 mm long; 1 mm wide; cartilaginous; much thinner on margins; yellow; without keel; 3 -veined. Lemma surface striate; without germination flap. Lemma margins flat. Lemma apex apiculate. Palea 2.3-2.7 mm long; cartilaginous.
    Flowers
    Lodicules 2; truncate. Anthers 3; 1.8-1.9 mm long; yellow. Stigmas purple; plumose. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; 2.2-2.4 mm long. Embryo 0.6 length of caryopsis. Hilum punctiform.
