    Habit
    Inflorescence a panicle, its primary branches bearing racemes at regular intervals along their length, each raceme reduced to a single sessile spikelet (whose apparent pedicel is homologous with the raceme peduncle).
    Florets
    Inferior floret barren. Superior floret bisexual, the lemma comprising the bilobed, hyaline base of the awn.
    Spikelets
    Pedicelled spikelet and pedicel completely suppressed. Spikelets solitary, sessile, 2-flowered.
