    Habit
    Annuals or perennials
    Leaves
    Leaf-blades convolute to lanceolate; ligule membranous or a line of hairs
    Inflorescences
    Inflorescence composed of untidy racemes, these digitate or in whorls on a short central axis; rhachis triquetrous, bearing paired or fascicled spikelets
    Spikelets
    Spikelets ovate to elliptic, dorsally compressed; glumes unequal, the lower shorter than the spikelet, acute to acuminate, the upper equalling the spikelet and ciliate on the margins; lower floret ♂, its lemma resembling the upper glume but eciliate, the palea short and deeply bifid; upper lemma chartaceous, acuminate to a short awn, its narrow inrolled margins covering only the edges of the acute palea
    Fruits
    Caryopsis elliptic-oblong.

    Inflorescences
    Inflorescence of irregular racemes, these digitate or in whorls on a short common axis, each with a slender weakly unilateral rhachis which is sometimes bare at the base, bearing the spikelets in pairs or clusters.
    Spikelets
    Spikelets narrowly ovate to elliptic.
    Glume
    Glumes acute to briefly awned, the superior as long as spikelet and ciliate on margins, the inferior c. 1/2 as long.
    Lemma
    Superior lemma crisply chartaceous with involute margins, shortly awned.
