Morphology General Habit
Perennial; caespitose. Butt sheaths persistent and investing base of culm; with compacted dead sheaths, or fibrous dead sheaths. Culms erect; slender; 10-45 cm long. Lateral branches lacking. Leaf-sheaths tubular for much of their length; glabrous on surface. Ligule a ciliolate membrane; 0.2-0.4 mm long. Leaf-blades flat, or conduplicate; 10-25 cm long; 1.5-3 mm wide; 1 cm long at summit of culm.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle capitate; oblong, or ovate; loose; 1-3 cm long; 0.5-0.7 cm wide. Primary panicle branches accrescent to a central 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; 4-7 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; 4-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; reaching apex of florets. Lower glume lanceolate, or ovate; 4-7 mm long; 1 length of upper glume; membranous; glaucous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate; muticous. Upper glume lanceolate, or ovate; 4-7 mm long; membranous; glaucous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate; muticous.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate, or ovate; 4-6 mm long; membranous; without keel; 5 -veined. Lemma surface pilose; hairy on veins. Lemma margins ciliate. Lemma apex dentate; 3-5 -fid; awned; 1 -awned. Principal lemma awn 0.5 mm long overall. Palea 2 -veined. Palea keels ciliolate.
