    Habit
    Annual. Culms 100-300 cm long; 7-13 mm diam.; 3-6 -noded; without nodal roots, or with prop roots. Culm-internodes distally pruinose. Culm-nodes glabrous, or pubescent, or bearded. Lateral branches sparse. Ligule an eciliate membrane; 0.7-3.7 mm long. Leaf-blades 5-70 mm wide.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle open; dense; 14-38 cm long; 2-3 cm wide. Primary panicle branches 1-14 -nate; sparsely divided; 6-10 cm long. Panicle branches angular, or flat; scabrous; pubescent in axils, or bearded in axils. Racemes 1.5-3.2 cm long; bearing a triad of spikelets, or few fertile spikelets; bearing 1(-3) fertile spikelets on each. Rhachis evident, or obsolete; fragile at the nodes; ciliate on margins. Rhachis internodes linear. Rhachis internode tip oblique. Spikelets in pairs, or in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster, or 2 in the cluster. Pedicels filiform; flattened; ciliate.
    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; dorsally compressed; 8-18 mm long; as long as fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 7-9 -veined; glabrous to pilose; ciliate on margins; entire, or dentate; 2 -fid; muticous, or mucronate, or awned; one glume awned; with 0-2.3 mm long awn. Companion sterile spikelet lemmas enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear, or elliptic; dorsally compressed; 17-18 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus cuneate; curved; 3.3-8.5 mm long; base pungent.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; dorsally compressed; 8-18 mm long; as long as fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 7-9 -veined; glabrous to pilose; ciliate on margins; entire, or dentate; 2 -fid; muticous, or mucronate, or awned; one glume awned; with 0-2.3 mm long awn. Companion sterile spikelet lemmas enclosed by glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear, or elliptic; dorsally compressed; 17-18 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus cuneate; curved; 3.3-8.5 mm long; base pungent.
    Glume
    Glumes dissimilar; with lower wider than upper; exceeding apex of florets; firmer than fertile lemma; dull, or shiny. Lower glume ovate; 1 length of spikelet; coriaceous; much thinner above; without keels; keel-less except near apex; 8-11 -veined. Lower glume surface glabrous to pilose. Lower glume apex acute. Upper glume ovate; coriaceous; much thinner above; without keels; 7 -veined. Upper glume surface glabrous to pilose. Upper glume margins eciliate, or ciliate.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline; 2 -veined; acute. Fertile lemma oblong; hyaline; 1 -veined. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 80-155 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
    Flowers
    Lodicules 2; oblong; 0.5-1 mm long; fleshy; glabrous, or ciliate. Anthers 3; 4.2-6 mm long. Stigmas 2. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; oblong; dorsally compressed; 2.5-5 mm long; apex umbonate.
