    [GB]
    Habit
    Annual. Culms erect; 100-360 cm long; 4-8 mm diam.; 4-6 -noded; without nodal roots, or with prop roots. Culm-nodes glabrous, or pubescent, or bearded. Leaves cauline. Ligule an eciliate membrane; 2-4 mm long; erose. Leaf-blades 10-15 mm wide. Leaf-blade surface hirsute; with tubercle-based hairs.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle contracted; linear, or lanceolate; 14-40 cm long; 2.5-4 cm wide. Primary panicle branches 1-14 -nate; not whorled; simple; 2-5 cm long. Panicle branches scabrous; glabrous in axils, or bearded in axils; with prominent pulvini. Racemes 1.5-3 cm long; bearing a triad of spikelets; bearing 1(-3) fertile spikelets on each. Rhachis fragile at the nodes; ciliate on margins. Rhachis hairs red; 1-1.6 mm long. Rhachis internodes linear; 5.5-6 mm long. Rhachis internode tip oblique. Spikelets in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 2 in the cluster. Pedicels filiform; straight, or curved (around sessile spikelet); 6-7 mm long; ciliate (rufously).
    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas; linear; 9-24 mm long; as long as fertile; persistent. Companion sterile spikelet glumes chartaceous; 5 -veined; glabrous, or pubescent, or villous; entire, or dentate; muticous, or awned; several-awned (the lower 3-awned); with 0-15 mm long awn. Companion sterile spikelet lemmas enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; (6-)10-15(-20) mm long; falling entire; deciduous with accessory branch structures. Spikelet callus linear; 3-6 mm long; pubescent; base pungent; attached obliquely.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas; linear; 9-24 mm long; as long as fertile; persistent. Companion sterile spikelet glumes chartaceous; 5 -veined; glabrous, or pubescent, or villous; entire, or dentate; muticous, or awned; several-awned (the lower 3-awned); with 0-15 mm long awn. Companion sterile spikelet lemmas enclosed by glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; (6-)10-15(-20) mm long; falling entire; deciduous with accessory branch structures. Spikelet callus linear; 3-6 mm long; pubescent; base pungent; attached obliquely.
    Glume
    Glumes dissimilar; with lower wider than upper; exceeding apex of florets; firmer than fertile lemma; shiny. Lower glume ovate; 1 length of spikelet; coriaceous; 2-keeled; keeled above; 9 -veined. Lower glume primary vein spinulose. Lower glume surface glabrous, or pubescent. Lower glume hairs dark brown. Lower glume apex rostrate. Upper glume ovate; coriaceous; without keels; 5-7 -veined. Upper glume surface glabrous, or pubescent. Upper glume muticous, or mucronate.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 0.8 length of spikelet; hyaline; 2 -veined; ciliolate on margins. Fertile lemma oblong; 3-5 mm long; hyaline; 1 -veined. Lemma margins ciliate. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; (4-)7.5-11(-15) mm long overall; with twisted column. Column of lemma awn glabrous, or pubescent; hairy on the spiral. Palea absent or minute.
    Flowers
    Lodicules 2; glabrous, or ciliate. Anthers 3; 3.6-5 mm long. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; oblong, or obovoid; 4-6.3 mm long; hairy at apex.
