Morphology General Habit
Perennial; caespitose; clumped densely. Butt sheaths withering. Basal innovations intravaginal. Culms 30-45 cm long. Culm-internodes distally glabrous. Leaf-sheaths open for most of their length; with 0 of their length closed; scaberulous. Leaf-sheath auricles erect. Ligule an eciliate membrane; 0.2 mm long. Leaf-blades filiform; conduplicate; elliptic in section; 0.4-0.65 mm wide; without exudate. Leaf-blade venation comprising 5 vascular bundles; with 3 inner ridges; with subepidermal sclerenchyma free from veins; with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with unevenly thickened subepidermal sclerenchyma layer on the underside. Leaf-blade surface scabrous; glabrous. Leaf-blade apex obtuse, or abruptly acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle smooth. Panicle open; lanceolate; 5-8 cm long. Panicle axis scabrous. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 8-9 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 8-9 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4.5-4.8 mm long; chartaceous; without keels; 3 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 5.5-6.2 mm long; 2.2-2.4 mm wide; chartaceous; glaucous and purple; suffused with last colour; without exudate; without keel; 5 -veined. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 2-3 mm long overall. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; glabrous. Hilum linear.
