Primary panicle branches naked below, or bearing spikelets almost to the base. Panicle axis scabrous. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; angular; scaberulous.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.6 mm long; pilose; obtuse.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.6 mm long; pilose; obtuse.
    Glume
    Glumes similar; with lower wider than upper; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 5.5-8.5 mm long; 0.9-1 length of upper glume; membranous; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume surface smooth, or asperulous. Lower glume apex acute; muticous, or mucronate. Upper glume lanceolate; 6-9.5 mm long; 0.9-1 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume lateral veins absent. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 1-1.3 mm long.
    Florets
    Fertile lemma linear; subterete; 6.5-8 mm long; coriaceous; without keel; 3 -veined. Lemma surface scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex awned; 3 -awned. Principal lemma awn 3-branched; with 3.5-7.5 mm long limb; with a straight or slightly twisted column. Column of lemma awn 1.5-2.8 mm long. Lateral lemma awns ascending; 2-5 mm long; shorter than principal; lemm awns 0.66 length of principal. Palea 1.5-1.7 mm long; 2 -veined. Palea apex dentate; 2 -fid.
    Flowers
