Morphology General Habit
Perennial; caespitose; clumped densely. Butt sheaths persistent and investing base of culm; with compacted dead sheaths. Culms erect; (25-)30-50(-60) cm long. Culm-internodes distally glabrous. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule a ciliolate membrane; 0.3-0.5 mm long. Leaf-blades curved; conduplicate; (10-)15-35(-60) cm long; (1.6-)2.2-2.8(-3.2) mm wide; pruinose. Leaf-blade venation comprising (8-)10-13(-17) vascular bundles; with 9-11 subepidermal sclerenchyma strands; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface glabrous. Leaf-blade apex acute; pungent.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 6-12 fertile spikelets. Peduncle tipped by a glumaceous appendage. Panicle spiciform; linear; (1.2-)3-3.5(-4.2) cm long. Panicle branches smooth, or scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2(-3) fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; (6-)6.5-7(-9.2) mm long; breaking up at maturity; disarticulating below each fertile floret.

Upper glume awn (1-)1.5-2.5(-3) mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; (5-)5.5-6.2(-6.9) mm long; membranous; without keel; 5 -veined. Lemma surface scabrous; rough above; glabrous. Lemma margins ciliolate. Lemma hairs 0.1-0.25 mm long. Lemma apex dentate; 5 -fid; awned; 5 -awned. Principal lemma awn 1-2.7 mm long overall. Lateral lemma awns 0.2-1.2 mm long. Palea 1 length of lemma. Palea surface puberulous; hairy on margins. Palea apex dentate; 2 -fid.
