    Habit
    Perennial. Rhizomes short. Culms erect; 70-110 cm long; 6-9 -noded; disarticulating at the nodes. Culm-internodes terete; solid; distally glabrous. Lateral branches ample. Leaf-sheaths striately veined; smooth, or scaberulous; glabrous on surface. Leaf-sheath oral hairs ciliate; 2-3 mm long. Ligule a fringe of hairs; 0.5-0.6 mm long. Leaf-blades straight, or curved; convolute; 2-20 cm long; 0.5-2 mm wide. Leaf-blade venation prominent. Leaf-blade surface scaberulous; rough adaxially, or on both sides. Leaf-blade margins scaberulous.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; linear; 6-20 cm long. Panicle axis smooth, or with occasional prickles. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; angular; scaberulous.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 6.5-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.6 mm long; pubescent; obtuse.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 6.5-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.6 mm long; pubescent; obtuse.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 8-13 mm long; 0.75-1.1 length of upper glume; membranous; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex entire, or dentate; 2 -fid; acute; muticous, or mucronate. Upper glume lanceolate; 8-13 mm long; 1 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume lateral veins absent. Upper glume apex dentate; 2 -fid; mucronate.
    Florets
    Fertile lemma linear; subterete; 8.5-11 mm long; coriaceous; without keel; 3 -veined. Lemma surface smooth, or scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex awned; 3 -awned. Principal lemma awn straight; with 10-22 mm long limb. Lateral lemma awns ascending; 8.5-18 mm long; shorter than principal. Palea 1.3-1.7 mm long; 2 -veined. Palea apex entire, or dentate; 2 -fid.
    Flowers
    Lodicules 2; 1.2-1.5 mm long. Anthers 3; 1.5-2.5 mm long.
    Fruits
