    Habit
    Densely tufted perennial, the basal sheaths silky tomentose; culms 20–100 cm. high.
    Leaves
    Leaf-blades 5–40 cm. long, 3–10 mm. wide.
    Inflorescences
    Inflorescence of 2–15 racemes on an axis 2–15 cm. long; racemes 2–5 cm. long, bearing the spikelets singly (or the longer racemes with paired spikelets at the base) on a pubescent to villous triquetrous rhachis.
    Spikelets
    Spikelets elliptic, 3–4.5 mm. long, pubescent to villous, acute, supported by a very short greenish stipe; lower glume 1/4–1/3 the length of the spikelet, clasping; upper glume and lower lemma membranous; upper lemma faintly striate, subacute.
    Habitat
    Damp soils and black clays; 0–1700 m.

    Habit
    Perennial; caespitose. Butt sheaths pubescent, or woolly. Culms 20-100 cm long. Ligule a fringe of hairs. Leaf-blades 5-40 cm long; 3-10 mm wide.
    Inflorescences
    Inflorescence composed of racemes. Racemes 2-15; borne along a central axis; unilateral; 2-5 cm long. Central inflorescence axis 2-15 cm long. Rhachis wingless; angular; pubescent on surface, or villous on surface. Spikelet packing adaxial; regular; 2 -rowed. Spikelets solitary (or paired at base). Fertile spikelets pedicelled. Pedicels 0.5-1 mm long; villous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 3-4.5 mm long; falling entire. Spikelet callus square (green).
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 3-4.5 mm long; falling entire. Spikelet callus square (green).
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; clasping; 0.25-0.33 length of spikelet; membranous; without keels; 3 -veined. Lower glume surface pubescent. Lower glume apex acute. Upper glume oblong; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface pubescent, or pilose, or villous. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; pubescent, or pilose, or villous; acute. Fertile lemma elliptic; 2.5-4 mm long; indurate; without keel. Lemma surface striate. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.
