    [GB]
    Habit
    Perennial; caespitose. Culms erect; 200-400 cm long. Ligule a ciliolate membrane. Leaf-blade base tapering to the midrib. Leaf-blades 100-300 cm long; 5-25 mm wide. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle open; elliptic; 25-40 cm long. Racemes 1-7 cm long. Rhachis tough; subterete. Rhachis internodes filiform. Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels filiform; unequal.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-5 mm long; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white to purple; 0.5-1 length of spikelet.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-5 mm long; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white to purple; 0.5-1 length of spikelet.
    Glume
    Glumes similar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels; 5 -veined. Lower glume surface flat; glabrous, or pilose. Lower glume margins ciliate. Lower glume apex dentate; 2 -fid. Upper glume lanceolate; without keels; 5 -veined. Upper glume surface glabrous, or pilose. Upper glume margins ciliate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 0.9 length of spikelet; hyaline; 1 -veined; ciliolate on margins; acute. Fertile lemma lanceolate; 1-2 mm long; hyaline; without keel; 1 -veined. Lemma margins ciliolate; hairy above. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; 1.5-6 mm long overall. Palea absent or minute.

    Habit
    Like M. sorghum but the callus beard half as long to as long as the spikelet, hairier than the glumes which are glabrous to thinly pilose.

    Habit
    Tall tufted perennial; culms 2–4 m. high.
    Leaves
    Leaf-blades up to 3 m. long, 5–25 mm. wide, narrowed to the midrib at the base.
    Inflorescences
    Panicle narrowly ovate to narrowly oblong, 25–40 cm. long; racemes 1–7 cm. long, usually much shorter than the supporting branches.
    Spikelets
    Spikelets 3–5 mm. long, the callus bearded with violet-tinged hairs from 1/2 to nearly as long as the spikelet; lower glume light brown, glabrous to thinly pilose; upper lemma entire or minutely bidentate, with a straight awn 1.5–6 mm. long.
