    Habit
    Annuals
    Leaves
    Leaf-blades flat; ligule membranous
    Inflorescences
    Inflorescence spike-like, its straight angular rhachis bearing deciduous sessile clusters of 7–9 spikelets; clusters cuneate, the 6–8 outer spikelets sterile (rarely ♂) pedicelled and involucral, the inner hermaphrodite and subsessile
    Spikelets
    Outer spikelets lanceolate to oblong, dorsally compressed; glumes subulate from a broad base; lower floret reduced to a membranous lemma as long as the spikelet; upper lemma reduced or absent Inner spikelet larger; lower glume suppressed, the upper subulate or oblong; lower floret reduced to a membranous lemma as long as the spikelet; upper lemma thinly chartaceous with the flat thin margins covering the palea
    Fruits
    Caryopsis lanceolate to oblong, dorsally compressed.

    Inflorescences
    Inflorescence a panicle. Panicle spiciform. Panicle axis bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile (1), or pedicelled (1); 1 in the cluster. Companion sterile spikelets pedicelled; 6-8 in the cluster. Involucre composed of imperfect spikelets. Pedicels linear.
    Spikelets
    Companion sterile spikelets well-developed; deciduous with the fertile. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 2.5-3.5-4.5 mm long; falling entire.
    Sterile
    Companion sterile spikelets well-developed; deciduous with the fertile.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 2.5-3.5-4.5 mm long; falling entire.
    Glume
    Glumes one the lower absent or obscure, or two (1); shorter than spikelet; thinner than fertile lemma. Lower glume subulate (1/1). Upper glume subulate (1), or oblong (1); membranous (1/1); without keels (1/1); 1 -veined (1/1). Upper glume apex acute (1/1).
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate (1), or oblong (1); membranous; 5 -veined (1), or 7 -veined (1); acute (1), or acuminate (1); muticous (1), or awned (1). Fertile lemma elliptic; chartaceous; without keel; 3 -veined. Lemma margins covering most of palea. Lemma apex acuminate; muticous (1), or awned (1); 1 -awned (1/1). Palea chartaceous; without keels.
