    Habit
    Perennial; caespitose. Rhizomes short. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Basal innovations extravaginal. Culms 20-50 cm long. Culm-internodes smooth. Leaf-sheaths 3-4 cm long; ribbed; smooth, or scaberulous; glabrous on surface. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles erect; 0.5-1 mm long. Ligule a ciliolate membrane; 0.5-1 mm long; erose. Leaf-blades straight, or curved; filiform; conduplicate; 8-12 cm long; 0.6-1.2 mm wide; stiff. Leaf-blade venation comprising 5 vascular bundles; with 7 subepidermal sclerenchyma strands. Leaf-blade surface ribbed; puberulous; hairy adaxially. Leaf-blade margins pubescent. Leaf-blade apex pungent.
    Inflorescences
    Inflorescence a panicle; comprising 15-25 fertile spikelets. Panicle open; linear; 6-12 cm long. Primary panicle branches ascending; 1-2 -nate; 3-8 cm long; bearing 3-5 fertile spikelets on each lower branch. Panicle axis 4-6 noded; smooth, or scaberulous. Panicle branches smooth, or scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels smooth, or scaberulous.
    Spikelets
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 8-12 mm long; 3-4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.6 mm long; pubescent. Floret callus 0.2-0.5 mm long; pilose; disarticulating transversely, or disarticulating obliquely.
    Fertile
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 8-12 mm long; 3-4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.6 mm long; pubescent. Floret callus 0.2-0.5 mm long; pilose; disarticulating transversely, or disarticulating obliquely.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 2.5-4.5 mm long; 0.7-0.8 length of upper glume; membranous; purple; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume margins ciliate. Lower glume apex acute; muticous, or awned; 1 -awned. Lower glume awn 0.4-0.8 mm long. Upper glume oblong; 3.5-5.3 mm long; 0.75 length of adjacent fertile lemma; membranous; purple; 1-keeled; 3 -veined. Upper glume primary vein scaberulous. Upper glume margins ciliate. Upper glume apex acute; muticous, or awned; 1 -awned. Upper glume awn 0.5-3 mm long.
    Florets
    Fertile lemma lanceolate; 5-7 mm long; membranous; glaucous; without keel; 5 -veined. Lemma margins ciliate. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1.5-4.2 mm long overall. Palea 5.5-6 mm long; 2 -veined. Palea keels scaberulous. Palea surface puberulous; hairy on back and on margins. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; 1-1.2 mm long; membranous; glabrous, or ciliate; 2-toothed. Anthers 3; 2-3 mm long; yellow. Ovary glabrous, or pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; 3.5 mm long; glabrous, or hairy at apex. Embryo 0.15 length of caryopsis. Hilum linear; 1 length of caryopsis.
