    Habit
    Perennial; caespitose. Culms geniculately ascending; 70-100 cm long. Ligule a fringe of hairs. Leaf-blades flat, or convolute; 45-50 cm long; 2-8 mm wide. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle; comprising 10-20 fertile spikelets. Panicle contracted; lanceolate; 9-23 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 33-60 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 33-60 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 33-60 mm long; 1 length of upper glume; scarious; purple; without keels; 5-9 -veined. Lower glume surface asperulous. Lower glume apex attenuate. Upper glume lanceolate; 33-60 mm long; 4-6 length of adjacent fertile lemma; scarious; purple; without keels; 5-9 -veined. Upper glume primary vein scaberulous. Upper glume apex attenuate.
    Florets
    Fertile lemma oblong; subterete; 8-10 mm long; cartilaginous; without keel; 9-11 -veined. Lemma lateral veins transversely connected at apex. Lemma surface pubescent; hairy above. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; with lobes 2-4 mm long; acute, or acuminate; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 27-45 mm long overall; with 17-27 mm long limb; with twisted column. Column of lemma awn 10-18 mm long. Lateral lemma awns arising on apex of lobes; 15-30 mm long; shorter than principal. Palea apex dentate; 2 -fid. Apical sterile florets 0-1 in number; barren; lanceolate; 0-1 mm long.
