    [GB]
    Habit
    Perennial; culms solitary, or caespitose. Rhizomes short. Culms erect; 80-100 cm long; 3.5 mm diam.; 5-6 -noded. Culm-internodes smooth; distally glabrous. Leaf-sheaths subequal to internodes, or longer than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane; 1-1.5 mm long; entire, or erose; truncate. Leaf-blades 20-30 cm long; 5-16 mm wide; coriaceous; glaucous. Leaf-blade surface smooth, or scaberulous; rough abaxially. Leaf-blade apex attenuate; simple, or soon splitting (becoming fibrous).
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect; bilateral; 20-25 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; lax; regular; 2 -rowed. Rhachis internodes 15-20 mm long. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 20-30 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent. Floret callus pubescent. Floret callus hairs 1 mm long.
    Fertile
    Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 20-30 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent. Floret callus pubescent. Floret callus hairs 1 mm long.
    Glume
    Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate, or oblong; 10-15 mm long; coriaceous; of similar consistency on margins, or much thinner on margins; without keels; 5-7 -veined. Lower glume lateral veins prominent. Lower glume surface smooth, or asperulous. Lower glume apex acute; muticous. Upper glume lanceolate, or oblong; 10-15 mm long; coriaceous; with undifferentiated margins, or membranous margins; without keels; 5-7 -veined. Upper glume lateral veins prominent. Upper glume surface smooth, or asperulous. Upper glume apex acute; muticous.
    Florets
    Fertile lemma lanceolate; 15 mm long; 2 mm wide; coriaceous; without keel; 5 -veined. Lemma apex acute; mucronate. Palea oblong; 0.66-0.75 length of lemma; 2 -veined. Palea keels smooth. Palea apex truncate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; oblong; 8 mm long; dark brown; hairy at apex; apex unappendaged. Hilum linear.
