    [GB]
    Habit
    Perennial; caespitose; clumped densely. Cataphylls inconspicuous. Basal innovations intravaginal. Culms slender; straight; 30-35 cm long; without nodal roots. Culm-internodes terete; smooth, or scaberulous. Culm-nodes without exudate; glabrous. Lateral branches lacking. Leaves mostly basal; 0-1 per branch. Leaf-sheaths tight; unthickened at base; open for most of their length; longer than adjacent culm internode; without keel; striately veined; glabrous on surface. Ligule an eciliate membrane; 3-5 mm long; membranous; white; scaberulous on abaxial surface; entire; acute. Leaf-blade base symmetrical. Leaf-blades straight; filiform; involute; angular in section; 5-11 cm long; 1-1.5 mm wide; coriaceous; stiff, or firm; yellowish green, or light green. Leaf-blade midrib indistinct. Leaf-blade venation indistinct; with subepidermal sclerenchyma strands unequal in size; with subepidermal sclerenchyma attached to veins below; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface ribbed; scabrous; puberulous; moderately hairy; hairy adaxially. Leaf-blade margins scabrous; glabrous. Leaf-blade apex obtuse.
    Inflorescences
    Inflorescence a panicle; with 1 peduncles per sheath. Peduncle terete; eglandular; glabrous. Panicle contracted; lanceolate, or elliptic; continuous; dense; equilateral; straight; 7-9 cm long; 2-4 cm wide; bearing few spikelets; contracted about primary branches. Primary panicle branches simple. Panicle axis angular; scaberulous. Spikelets in pairs. Fertile spikelets pedicelled. Pedicels angular; unequal; 4-5 mm long, or 8-15 mm long; scabrous.
    Spikelets
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous. Rhachilla internodes zig-zag; scaberulous. Floret callus glabrous.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous. Rhachilla internodes zig-zag; scaberulous. Floret callus glabrous.
    Glume
    Glumes persistent; similar; with lower narrower than upper; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-10 mm long; 0.66 length of upper glume; hyaline, or membranous; pallid, or light brown; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acuminate. Upper glume lanceolate; 11-15 mm long; 0.5 length of adjacent fertile lemma; membranous; pallid, or light green, or light brown; without keels; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acuminate.
    Florets
    Fertile lemma lanceolate; symmetrical; 22-30 mm long; chartaceous; pallid, or light green, or light brown; without keel; 5 -veined. Lemma surface scaberulous. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn stiff; 5-7 mm long overall. Palea 0.66 length of lemma; 2 -veined. Palea keels scaberulous. Palea surface scaberulous. Palea apex acuminate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; lanceolate, or oblong; concavo-convex; 3.5 mm long; glabrous. Hilum linear.
