    Habit
    Annual. Culms decumbent; 5-30 cm long; rooting from lower nodes. Culm-internodes distally glabrous. Culm-nodes glabrous, or bearded. Lateral branches lacking, or ample; arising from lower culm. Leaf-sheaths mostly shorter than adjacent culm internode; glabrous on surface, or pilose; with tubercle-based hairs; outer margin hairy. Ligule an eciliate membrane; 0.3-0.6 mm long; erose. Leaf-blade base cordate. Leaf-blades lanceolate, or elliptic; 25-37 cm long; 4-9 mm wide. Leaf-blade surface glabrous, or pilose; sparsely hairy, or moderately hairy, or densely hairy; with tubercle-based hairs. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; terminal and axillary. Peduncle 2-12 cm long. Panicle open, or contracted; lanceolate, or ovate; 2-10 cm long. Panicle branches glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 5-14 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets obovate; dorsally compressed; 1.2-1.8 mm long; 0.5 mm wide; falling entire; deciduous from the base, or with the pedicel. Rhachilla internodes elongated between glumes. Rhachilla elongation 0.25 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets obovate; dorsally compressed; 1.2-1.8 mm long; 0.5 mm wide; falling entire; deciduous from the base, or with the pedicel. Rhachilla internodes elongated between glumes. Rhachilla elongation 0.25 mm long.
    Glume
    Glumes reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 0.7-1.4 mm long; 0.6-0.75 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 3 -veined; glabrous, or pubescent; acute. Fertile lemma elliptic; dorsally compressed; 1-1.3 mm long; indurate; pallid; without keel. Lemma surface smooth. Lemma margins involute. Lemma apex acute. Palea involute; indurate.
