    Habit
    Tufted perennial; culms 30–40 cm. high.
    Leaves
    Leaf-blades narrowly lanceolate, 2–5 cm. long, 4–12 mm. wide, velvety pubescent.
    Inflorescences
    Inflorescence of 2–5 racemes on a common axis 1–4 cm. long; racemes 1–3 cm. long, bearing paired spikelets on a triquetrous rhachis.
    Spikelets
    Spikelets broadly elliptic, 2.5–4 mm. long, acute to acuminate; lower glume cuff-like, up to 1/4 the length of the spikelet, truncate; upper glume and lower lemma thickly coriaceous, spinosely warty; lower palea with membranous centre flanked by coriaceous keels; upper lemma not much shorter than the lower, granulose, subacute, mucronulate (0.2 mm.).
    Habitat
    Coastal and semi-desert bushland; 200–1600 m.
    Distribution

    [GB]
    Habit
    Perennial; caespitose. Culms 30-40 cm long. Ligule a fringe of hairs. Leaf-blades lanceolate; 2-5 cm long; 4-12 mm wide. Leaf-blade surface pubescent; densely hairy.
    Inflorescences
    Inflorescence composed of racemes. Racemes 2-5; borne along a central axis; unilateral; 1-3 cm long. Central inflorescence axis 1-4 cm long. Rhachis angular. Spikelet packing irregular; 2-3 -rowed. Spikelets in pairs. Fertile spikelets sessile and pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; plano-convex; acute, or acuminate; 2.5-4 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; plano-convex; acute, or acuminate; 2.5-4 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblate; clasping; 0.1-0.25 length of spikelet; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate. Upper glume elliptic; 1 length of spikelet; coriaceous; without keels; 11 -veined. Upper glume surface spinose and tuberculate. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; coriaceous; 7 -veined; spinulose and tuberculate; cuspidate. Palea of lower sterile floret becoming indurate on keels at maturity. Fertile lemma elliptic; dorsally compressed; 2-3 mm long; indurate; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex obtuse, or acute; mucronate. Principal lemma awn 0.2 mm long overall. Palea indurate.
    Distribution
