    Habit
    Perennial; caespitose. Culms 25-70 cm long. Leaf-sheaths glabrous on surface. Leaf-sheath auricles falcate. Ligule a ciliolate membrane; 0.5-1 mm long. Leaf-blades convolute; 10-35 cm long; 4-7 mm wide; coriaceous; stiff; glaucous. Leaf-blade surface pubescent; hairy adaxially, or on both sides.
    Inflorescences
    Inflorescence composed of racemes; embraced at base by subtending leaf. Racemes 1; single; linear; bilateral; 5-15 cm long. Rhachis scabrous on margins; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear; 8 mm long. Spikelets appressed; solitary, or in pairs. Fertile spikelets sessile; 1-2 in the cluster.
    Spikelets
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-27 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-27 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume subulate; 1 length of upper glume; coriaceous; 1 -veined. Lower glume lateral veins absent. Upper glume subulate; 14-18 mm long; 1 length of adjacent fertile lemma; coriaceous; 1 -veined. Upper glume lateral veins absent.
    Florets
    Fertile lemma lanceolate; 14-18 mm long; coriaceous; without keel; 5 -veined. Lemma surface smooth, or scaberulous; rough above. Lemma margins ciliate. Lemma hairs 3-5 mm long. Lemma apex dentate; 2 -fid; muticous, or awned; 1 -awned. Principal lemma awn from a sinus; 1-10 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels ciliate. Palea surface pubescent; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
