    Habit
    Perennial; caespitose; clumped densely. Culms geniculately ascending; 15-50 cm long; swollen at the base. Culm-internodes distally pubescent (in lines). Culm-nodes glabrous. Lateral branches lacking. Leaves cauline; 3-15 per branch. Leaf-sheaths 2-3 cm long; keeled; glabrous on surface; outer margin hairy. Leaf-sheath oral hairs lacking, or ciliate. Leaf-sheath auricles erect; 0.5 mm long. Ligule a ciliolate membrane; 0.3-0.6 mm long. Leaf-blade base cuneate; asymmetrical; with a brief petiole-like connection to sheath; petiole 0.1-0.2 cm long; petiole pubescent. Leaf-blades lanceolate; 6-16 cm long; 3-30 mm wide; mid-green, or mid-green and purple; discolorous with last colour beneath. Leaf-blade surface glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
    Inflorescences
    Monoecious; with male and female spikelets in the same inflorescence. Inflorescence composed of racemes; terminal and axillary; subtended by an unspecialized leaf-sheath, or bracts (1 bract when a short basal branch present); embraced at base by subtending leaf; with 1-4 peduncles per sheath. Axillary inflorescences similar to terminal. Peduncle 4-8 cm long; pubescent above. Racemes 1; single; 2-4 cm long; bearing few fertile spikelets; bearing 1(-4) fertile spikelets on each. Sexes segregated; on bisexual branches; with male below; with 4-12 male spikelets per branch. Spikelets solitary. Fertile spikelets pedicelled. Male spikelets pedicelled. Pedicels 0.5-3 mm long.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 11-15 mm long; falling entire, or breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes deciduous; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-10 mm long; 1 length of upper glume; chartaceous; without keels; 5(-8) -veined. Lower glume lateral veins convergent at apex. Lower glume surface glabrous, or puberulous; inner surface scabrous (above). Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 4.5-8 mm long. Upper glume lanceolate; 7-10 mm long; chartaceous; without keels; 3 -veined. Upper glume surface glabrous, or puberulous. Upper glume apex acute; awned; 1 -awned. Upper glume awn 2.5-5 mm long.
    Florets
    Fertile florets female. Fertile lemma elliptic; 7-8 mm long; 1.7-2 mm wide; indurate; pallid and purple; mottled with last colour; shiny; without keel. Lemma surface pubescent. Lemma margins convolute; covering most of palea. Lemma hairs 1 mm long. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1-1.5 mm long overall. Palea indurate.
    Fruits
    Disseminule comprising a spikelet.
    Spikelets
    Male spikelets distinct from female; 1 flowered; separately deciduous; linear; 7-8 mm long; hairy. Male spikelet glumes absent. Male spikelet lemma 7-8 mm long; 3 -veined; awned; with 1-2 mm long awn. Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 11-15 mm long; falling entire, or breaking up at maturity; disarticulating below each fertile floret.
    Male
    Male spikelets distinct from female; 1 flowered; separately deciduous; linear; 7-8 mm long; hairy. Male spikelet glumes absent. Male spikelet lemma 7-8 mm long; 3 -veined; awned; with 1-2 mm long awn.
