    Panicle ovate, 3–15 cm. long, diffuse, rarely linear and ± condensed, the branches capillary and tinged with red.
    Spikelets
    Spikelets 1.4–2.1 mm. long, greyish green or sometimes dark green; lower glume narrowly ovate, 0.8–1.1 mm. long; upper glume narrowly ovate, 0.8–1.5 mm. long, 1/2–2/3 as long as the spikelet, acute; lemma narrowly ovate, as long as the spikelet, acute; anthers 3, 0.8–1 mm. long.

    Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

    Habit
    Densely caespitose perennial without rhizomes or stolons; culms up to 40(55) cm tall, erect, unbranched; basal leaf sheaths chartaceous, tomentose on the margins with curly yellow or brown hairs, terete, decaying with age into a compact mass of fine fibres, the woolly hairs retained within; leaf laminas 3–15 cm long, involute-filiform, smooth or scaberulous on the surface, scabrid on the margins.
    Inflorescences
    Panicle 3–15 cm long, ovate and diffuse or rarely linear and somewhat condensed; primary branches not in whorls, capillary, tinged with red, smooth or scaberulous, eglandular, the spikelets evenly distributed.
    Spikelets
    Spikelets (1.2)1.4–2.1 mm long, greyish-green or sometimes dark greenish-purple or olive; inferior glume 1/3–2/3 the length of the spikelet, narrowly ovate to oblong, nerveless, glabrous or minutely hispidulous, acute to acuminate or obtuse-denticulate at the apex; superior glume 1/2–2/3(4/5) the length of the spikelet, narrowly ovate, 1-nerved, glabrous or minutely hispidulous, acute at the apex; lemma as long as the spikelet, narrowly ovate, acute; anthers 3, 0.8–1.2 mm long.
    Fruits
    Grain 0.5–0.7 mm long, obovate, truncate.
    [GB]
    Habit
