    [GB]
    Habit
    Annual, or perennial; short-lived; caespitose. Butt sheaths glabrous, or pilose. Culms 8-45 cm long. Culm-nodes glabrous, or pubescent. Ligule a ciliate membrane. Leaf-blades flat, or conduplicate, or involute; 5-12 cm long; 1-2 mm wide.
    Inflorescences
    Inflorescence composed of racemes; exserted, or embraced at base by subtending leaf. Racemes 2; paired; appressed back to back; oblong; 2 cm long. Rhachis fragile at the nodes; flattened; ciliate on margins. Rhachis hairs red. Rhachis internodes linear. Rhachis internode tip oblique. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; flattened; ciliate; tip rectangular.
    Spikelets
    Basal sterile spikelets well-developed; 3-5 in number (lower raceme); 3-5 in upper raceme; paired with a fertile pedicelled spikelet; subsessile; male; cuneate; 7 mm long; larger than fertile. Basal sterile spikelet glumes coriaceous; glabrous; lemmas awnless. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus base truncate; attached transversely.
    Sterile
    Basal sterile spikelets well-developed; 3-5 in number (lower raceme); 3-5 in upper raceme; paired with a fertile pedicelled spikelet; subsessile; male; cuneate; 7 mm long; larger than fertile. Basal sterile spikelet glumes coriaceous; glabrous; lemmas awnless.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus base truncate; attached transversely.
    Glume
    Glumes dissimilar; reaching apex of florets; firmer than fertile lemma. Lower glume cuneate; 4-4.5 mm long; 1 length of spikelet; chartaceous; without keels; 7 -veined. Lower glume surface with transverse tufts of hair. Lower glume apex dentate; 3 -fid; truncate. Upper glume elliptic; 5.5 mm long; membranous; without keels; 3 -veined. Upper glume margins ciliate. Upper glume apex acute; awned; 1 -awned. Upper glume awn 5-7 mm long.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret elliptic; hyaline; 1 -veined; without lateral veins; acute. Fertile florets bisexual, or female. Fertile lemma elliptic; 4 mm long; hyaline; without keel; 3 -veined. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 17 mm long overall; with twisted column. Column of lemma awn 5 mm long; glabrous. Palea hyaline.
    Flowers
    Lodicules absent. Anthers 2.
