Ligule a fringe of hairs; 0.3 mm long. Collar glabrous, or pubescent. Leaf-blades involute; 7-15 cm long; 1.5 mm wide. Leaf-blade surface scabrous; rough on both sides.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; linear; 12-16 cm long; 3-4 cm wide. Primary panicle branches 4-8 cm long; bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 7-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1-1.5 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 7-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1-1.5 mm long; pubescent; acute.
    Glume
    Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-13 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1-1.5 mm long. Upper glume lanceolate; 7-13 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface asperulous. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-2 mm long.
    Florets
    Fertile lemma lanceolate; subterete; 7-10.5 mm long; coriaceous; pallid, or light brown; without keel; 3 -veined. Lemma midvein without distinctive roughness, or scabrous. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; reflexed; with 18-25 mm long limb; with twisted column; persistent. Column of lemma awn 1.3-3 mm long. Lateral lemma awns 16-23 mm long; shorter than principal. Palea 0.2 length of lemma; without keels.
