Ligule a fringe of hairs. Leaf-blades curled; conduplicate; 5-20 cm long; 1-2 mm wide; stiff. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; effuse; 10-25 cm long; 6-13 cm wide; with spikelets clustered towards branch tips. Primary panicle branches spreading; 1 -nate; 2-10 cm long. Panicle branches glandular (in axils); scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.4-0.5 mm long; pilose; obtuse.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.4-0.5 mm long; pilose; obtuse.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 6.5-8 mm long; 1.1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate; mucronate. Upper glume lanceolate; 6-7 mm long; 1.1-1.2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins absent. Upper glume apex emarginate, or acute; mucronate.
    Florets
    Fertile lemma elliptic; subterete; 5-6 mm long; coriaceous; without keel; 3 -veined. Lemma surface smooth, or scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; with 7-14 mm long limb; persistent. Lateral lemma awns 7-14 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
