    Leaf lamina
    Leaf laminae 2.5–8 cm. long and 2–9 mm. wide, narrowly lanceolate, flat, acuminate.
    Inflorescences
    Panicle 4–8(20) cm. long, broadly ovate, glabrous or pilose, sparsely branched, the branches spreading at maturity.
    Spikelets
    Spikelets 3–4 mm. long, ovate, pilose or glabrous, acuminate; inferior glume as long as the spikelet, 3(5)-nerved; superior glume 7-nerved; inferior lemma 5-nerved, its palea poorly developed, sterile; superior lemma and palea pallid.
