    Habit
    Annual. Culms geniculately ascending, or decumbent; 30-40 cm long; rooting from lower nodes. Culm-internodes terete; striate. Culm-nodes pubescent. Lateral branches ample. Leaf-sheaths mostly shorter than adjacent culm internode; without keel; striately veined; pubescent; with tubercle-based hairs. Ligule a fringe of hairs. Leaf-blades linear, or lanceolate; 2-6 cm long; 3-7 mm wide. Leaf-blade surface glabrous. Leaf-blade margins crenate; scabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 5-6; borne along a central axis; unilateral; 1.5-2 cm long. Rhachis narrowly winged; 0.75 mm wide; pubescent on surface; ciliate on margins. Rhachis hairs purple. Spikelet packing crowded; regular; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; compressed slightly; acuminate; 3.5 mm long; falling entire. Spikelet callus brief.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; compressed slightly; acuminate; 3.5 mm long; falling entire. Spikelet callus brief.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 0.5 length of spikelet; membranous; without keels; 3 -veined. Lower glume surface pubescent. Lower glume apex acute. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume primary vein obscure. Upper glume lateral veins obscure. Upper glume surface pubescent. Upper glume margins villous. Upper glume hairs purple. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; 5 -veined; villous; bearing purple hairs; acuminate. Fertile lemma 2.5 mm long; indurate; pallid; without keel. Lemma surface punctate. Palea without keels.
