    Habit
    Annual. Culms 10-30 cm long; rooting from lower nodes. Ligule a fringe of hairs. Leaf-blades lanceolate; stiff.
    Inflorescences
    Inflorescence composed of racemes. Racemes borne along a central axis; spreading, or deflexed; unilateral. Rhachis flattened; terminating in a barren extension; extension subulate. Spikelet packing abaxial; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
