    Habit
    Perennial; culms solitary, or caespitose. Butt sheaths red; persistent and investing base of culm; with fibrous dead sheaths. Basal innovations extravaginal. Culms slender; 6-45 cm long. Culm-internodes smooth. Leaf-sheaths 3-10 cm long; wider than blade at the collar; ribbed; glabrous on surface. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles erect; 0.7-1.7 mm long. Ligule an eciliate membrane; 0.7-1.7 mm long. Leaf-blades filiform; involute; angular in section; 4-10(-20) cm long; 0.3-0.4 mm wide. Leaf-blade venation comprising 3-5 vascular bundles; with 5-7 subepidermal sclerenchyma strands. Leaf-blade surface ribbed; puberulous and pilose; hairy adaxially (puberulous), or abaxially (pilose).
    Inflorescences
    Inflorescence a panicle; comprising 3-6 fertile spikelets. Panicle open; 2-3.5 cm long. Primary panicle branches ascending, or spreading; 1-2 -nate; 1.5-2.5 cm long; bearing 1-2 fertile spikelets on each lower branch; bearing spikelets almost to the base. Panicle axis 3-6 noded; scaberulous. Panicle branches scaberulous; with prominent pulvini. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scaberulous.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 6-9 mm long; 2-3 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.8-1.1 mm long; pubescent. Floret callus 0.1-0.2 mm long; glabrous; disarticulating transversely.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 6-9 mm long; 2-3 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.8-1.1 mm long; pubescent. Floret callus 0.1-0.2 mm long; glabrous; disarticulating transversely.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 2.5-3.5 mm long; 0.75 length of upper glume; membranous; much thinner on margins; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume margins ciliate. Lower glume apex acute. Upper glume oblong; 3-5 mm long; 0.75-1 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume margins ciliate. Upper glume apex emarginate, or acute.
    Florets
    Fertile lemma lanceolate; 4-5 mm long; membranous; much thinner on margins; without keel; 5 -veined. Lemma surface scaberulous. Lemma apex dentate; 2 -fid; acute; awned; 1 -awned. Principal lemma awn from a sinus; 0.5-2 mm long overall. Palea 4-5.5 mm long; 2 -veined. Palea keels scabrous; adorned all along. Palea surface puberulous; hairy on back and on margins; hairy all along, or above. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; 0.6-1 mm long; membranous; glabrous, or ciliate; 2-toothed. Anthers 3; 0.5-0.9 mm long, or 1.2-1.6 mm long; retained within floret, or eventually exserted; purple. Ovary glabrous, or pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; 2.5-3 mm long; glabrous, or hairy at apex. Embryo 0.2 length of caryopsis. Hilum linear; 1 length of caryopsis.
