    Leaves
    Leaf-blades broadly linear to narrowly lanceolate; ligule membranous
    Inflorescences
    Inflorescence composed of racemes borne along a central axis; rhachis triquetrous bearing solitary pedicellate spikelets, their lower glume adaxial
    Spikelets
    Spikelets narrowly lanceolate, dorsally compressed; lower glume ovate, ± 1/5 the length of the spikelet; upper glume a little shorter than the spikelet, awned; lower floret barren, represented by a membranous lemma as long as the spikelet and terminating in a flexuous awn; upper lemma chartaceous, acuminate to aristulate, its flat thin margins enfolding and concealing the palea
    Fruits
    Caryopsis narrowly oblong.
    Habit
    Annual

    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; unilateral. Rhachis angular. Spikelet packing adaxial. Spikelets ascending; solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5-6.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5-6.5 mm long; falling entire.
    Glume

Upper glume lanceolate; membranous; without keels; 3 -veined. Upper glume surface setose; with tubercle-based hairs. Upper glume apex acuminate; awned; 1 -awned.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; membranous; acuminate; awned. Fertile lemma lanceolate; laterally compressed; chartaceous; much thinner on margins; without keel; 5 -veined. Lemma margins covering most of palea. Lemma apex acuminate; muticous, or awned; 1 -awned. Palea chartaceous; without keels.
