Lower glume apex acute. Upper glume ovate; 1.3-1.5 mm long; 0.75-0.8 length of adjacent fertile lemma; membranous; dark green; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

    Leaves
    Leaf-blades flat, 20–40 cm. long, mostly 6–9 mm. wide, soft and shining, usually smooth with the secondary veins clearly visible, rarely sparsely pilose or scaberulous.
    Inflorescences
    Panicle lanceolate to narrowly ovate, 15–40 cm. long, graceful, rather diffuse, the primary branches filiform and bare for most of their length, the spikelets ± appressed along the length of the secondary branches.
    Spikelets
    Spikelets 1.6–2 mm. long, dark green; lower glume lanceolate, 0.7–1.3 mm. long; upper glume narrowly ovate, 1.3–1.5 mm. long, 3/4–4/5 as long as the spikelet; lemma narrowly ovate, as long as the spikelet; anthers 3, 0.8 mm. long.
    Fruits
    Grain ellipsoid, 0.7 mm. long.
