Morphology General Habit
Perennial; caespitose. Culms erect; 30-55 cm long. Lateral branches lacking. Leaf-sheaths tubular for much of their length; glabrous on surface, or hirsute. Ligule an eciliate membrane; 0.2-0.4 mm long. Leaf-blades flat, or conduplicate; 20-30 cm long; 4-5 mm wide; 0.8-1.5 cm long at summit of culm; stiff. Leaf-blade venation with 17-19 secondary veins. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle capitate; oblong; 1.5-2.5 cm long; 0.9 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis, or with lateral stumps on axis. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets represented by a single scale; 2 in number. Basal sterile spikelet glumes membranous. Spikelets comprising 2-3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Sterile
Basal sterile spikelets represented by a single scale; 2 in number. Basal sterile spikelet glumes membranous.
Fertile
Spikelets comprising 2-3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 4-5 mm long; 1 length of upper glume; membranous; 1-keeled; 1-3 -veined. Lower glume lateral veins absent, or distinct. Lower glume apex acute; awned; 1 -awned. Lower glume awn 1 mm long. Upper glume ovate; 4-5 mm long; membranous; 1-keeled; 1-3 -veined. Upper glume lateral veins absent, or distinct. Upper glume apex acute; awned; 1 -awned. Upper glume awn 1 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 4-5 mm long; membranous; without keel; 3-5 -veined. Lemma surface glabrous, or pilose; hairy on veins. Lemma margins ciliate. Lemma apex dentate; 3-5 -fid; awned; 1-3 -awned. Principal lemma awn 1-2 mm long overall. Lateral lemma awns 0.5 mm long. Palea 5 mm long; 2 -veined. Palea keels ciliolate. Palea apex muticous, or awned; awns 0-0.3 mm long.
