Culm-internodes terete; solid; yellow, or mid-green. Lateral branches dendroid; extravaginal. Branch complement many; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths brown, or purple; concolorous, or distinctly mottled with last colour; antrorsely scabrous; pilose; without auricles. Culm-sheath ligule 3.5 mm high; ciliate. Culm-sheath blade linear; 15 cm long. Leaves 3-6 per branch. Leaf-sheaths outer margin hairy. Leaf-sheath oral hairs ciliate; 2-3 mm long. Ligule an eciliate membrane; 0.5 mm long; erose. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.05-0.1 cm long. Leaf-blades deciduous at the ligule; linear; 6-10 cm long; 4-7 mm wide; light green. Leaf-blade surface pubescent; sparsely hairy; hairy adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate; dense; 4-7 cm long; 1-2 cm wide. Primary panicle branches ascending; bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-2 mm long; scaberulous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acute; 11-12.3 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acute; 11-12.3 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5 mm long; 0.5 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 1.1 mm long; 0.1 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 6.4-7 mm long; chartaceous; 7 -veined; acute; mucronate. Lemma of upper sterile floret ovate; 7 mm long; chartaceous; acute; mucronate. Fertile lemma ovate; 10.5-12 mm long; coriaceous; without keel; 11-14 -veined. Lemma apex acute. Palea 1.1 length of lemma; 7-8 -veined. Palea keels approximate. Palea apex dentate; 2 -fid.
    Flowers
    Lodicules 3; membranous; veined; ciliate. Anthers 3. Stigmas 2.
    Fruits
