    Habit
    Annual; caespitose; clumped loosely. Culms erect, or geniculately ascending; 30-50 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 10-20 cm long; 4-10 mm wide. Leaf-blade surface glabrous, or pilose; hairy on both sides; with tubercle-based hairs. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; moniliform; smoothly terete; bilateral; 4-8 cm long; bearing 6-8 fertile spikelets on each. Rhachis fragile at the nodes; semiterete. Spikelet packing broadside to rhachis. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Basal sterile spikelets absent, or rudimentary; 0-2 in number. Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 10-14 mm long; falling entire; deciduous with accessory branch structures.
    Sterile
    Basal sterile spikelets absent, or rudimentary; 0-2 in number.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 10-14 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes similar; shorter than spikelet. Lower glume oblong; asymmetrical; 8-10 mm long; 1 length of upper glume; coriaceous; without keels; 7-9 -veined. Lower glume lateral veins unequally thickened; ribbed. Lower glume surface pubescent. Lower glume apex dentate; 2-4 -fid; truncate. Upper glume oblong; asymmetrical; 8-10 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 7-9 -veined. Upper glume lateral veins unequally thickened; ribbed; parallel at apex. Upper glume surface pubescent. Upper glume apex dentate; 2-4 -fid; truncate.
    Florets
    Fertile lemma oblong; 10-12 mm long; coriaceous; keeled; 5 -veined. Lemma apex entire, or dentate; 2 -fid; with irregular lobes; truncate; muticous, or awned; 1 -awned. Principal lemma awn flat below; 50-80 mm long overall (becoming longer above, but shorter than raceme). Palea 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; ciliate. Ovary with a fleshy appendage below style insertion; pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a rhachis internode.
