    Habit
    Perennial; caespitose. Butt sheaths pilose. Basal innovations intravaginal. Culms erect; 90-100 cm long; 2 -noded. Leaf-sheaths without keel; smooth. Ligule an eciliate membrane; 5-6 mm long; truncate. Leaf-blades filiform; conduplicate, or convolute; 40-50 cm long; 1-3 mm wide; stiff. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; nodding; 25 cm long. Primary panicle branches spreading; 2-3 -nate. Panicle axis pubescent. Panicle branches pilose. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 18 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes pilose; with 5-6 mm long hairs. Floret callus pilose; with elliptic scar.

Floret callus pilose; with elliptic scar.
    Glume
    Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma; shiny. Lower glume lanceolate; 16 mm long; 0.9 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate. Upper glume elliptic; 18 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate.
    Florets
