    Habit
    Perennial; caespitose; clumped densely. Butt sheaths persistent and investing base of culm; with compacted dead sheaths. Basal innovations intravaginal. Culms 18-46 cm long. Leaf-sheaths open for most of their length; with 0.33-0.4 of their length closed; with flat margins; glabrous on surface. Leaf-sheath auricles erect; obtuse. Ligule an eciliate membrane. Leaf-blades filiform; conduplicate; circular in section; 0.5-0.85 mm wide; glaucous; pruinose. Leaf-blade venation comprising 7 vascular bundles; with 1 inner ridges; with subepidermal sclerenchyma free from veins; with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface smooth; pilose; hairy adaxially. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; 4.4-5.5 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
    Fertile
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 3.5-4.2 mm long; 0.8-0.9 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.
    Florets
    Fertile lemma ovate; 4.2-4.7 mm long; chartaceous; without keel; 5 -veined. Lemma surface pubescent. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1.4-1.5 mm long overall. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
