    [GB]
    Habit
    Perennial; caespitose. Rhizomes short. Culms 15-25 cm long. Leaf-sheath oral hairs lacking, or scanty. Ligule a fringe of hairs; 0.4 mm long. Leaf-blades erect; aciculate; convolute; 1-6 cm long; 0.6-1 mm wide; stiff; glaucous. Leaf-blade surface ribbed; glabrous, or pubescent. Leaf-blade apex acute; pungent.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; elliptic; 3-5 cm long; 1 cm wide; bearing few spikelets. Primary panicle branches simple. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; curved; 1.2-4 mm long; bearded; with longer hairs above; obtuse. Floret callus hairs 0.3-0.4 length of lemma.
    Fertile
    Spikelets comprising 4 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; curved; 1.2-4 mm long; bearded; with longer hairs above; obtuse. Floret callus hairs 0.3-0.4 length of lemma.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 10-15 mm long; 1.1 length of upper glume; scarious; without keels; 5 -veined. Lower glume surface pubescent; hairy above. Lower glume apex acute. Upper glume lanceolate; 9-14 mm long; 2 length of adjacent fertile lemma; scarious; without keels; 5 -veined. Upper glume surface pubescent; hairy above. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 4.5-6 mm long; coriaceous; without keel; 9 -veined. Lemma surface glabrous; with a transverse row of hair tufts; bearing 6 hair tufts in all. Lemma hairs 2-2.5 mm long. Lemma apex lobed; 2 -fid; with lanceolate lobes; incised 0.5-0.6 of lemma length; acuminate; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 8-10 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 1.5 mm long; shorter than principal. Palea 0.5 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; fleshy; glabrous. Anthers 3; 3.5 mm long. Ovary pubescent all over.
    Fruits
    Caryopsis with free brittle pericarp; 2.5 mm long. Embryo 0.2-0.33 length of caryopsis. Hilum punctiform.
