Leaf-blades curled; filiform; convolute; 15-30 cm long; 1-1.5 mm wide; coriaceous; stiff. Leaf-blade surface ribbed; pubescent; hairy adaxially. Leaf-blade apex muticous, or pungent.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; lanceolate; 6-12 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 17-25 mm long; 5-10 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse; disarticulating obliquely.
    Fertile
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 17-25 mm long; 5-10 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse; disarticulating obliquely.
    Glume
    Glumes persistent; similar; exceeding apex of florets. Lower glume lanceolate; 18-24 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex setaceously attenuate. Upper glume lanceolate; 18-24 mm long; 3 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex setaceously attenuate.
    Florets
    Fertile lemma oblong; 6-8 mm long; membranous; without keel; 7-9 -veined. Lemma surface pilose. Lemma apex lobed; 2 -fid; with lobes 1.5-3 mm long; incised 0.33-0.5 of lemma length; acuminate; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 15-20 mm long overall; with twisted column. Lateral lemma awns arising on inner edge of lobes; 7-10 mm long; shorter than principal. Palea oblong; 1 length of lemma; 2 -veined. Palea surface pubescent; hairy on back and on flanks. Rhachilla extension 0.5-1 mm long.
    Flowers
