Morphology General Habit
Perennial; caespitose. Butt sheaths thickened and forming a bulb; persistent and investing base of culm; with compacted dead sheaths. Culms erect; 10-40 cm long. Leaf-sheaths pubescent. Ligule an eciliate membrane; 1 mm long. Leaf-blades 12-15 cm long; 1.5-2.5 mm wide. Leaf-blade surface pubescent. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle spiciform; oblong; 1.8-2 cm long; 0.7 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; ovate. Basal sterile spikelet glumes membranous. Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 5.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Sterile
Basal sterile spikelets represented by a single scale; 2 in number; ovate. Basal sterile spikelet glumes membranous.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 5.5 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; 3 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume margins ciliolate. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1-1.8 mm long. Upper glume ovate; 3 mm long; 0.6 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface pubescent. Upper glume margins ciliolate. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-1.5 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic, or oblong; 5 mm long; membranous; without keel; rounded except near apex; 3-5 -veined. Lemma apex dentate; 5 -fid; awned; 5 -awned. Principal lemma awn 2.5-3.5 mm long overall. Lateral lemma awns arising on apex of lobes; shorter than principal. Palea 1 length of lemma; 2 -veined. Palea keels pubescent. Palea apex dentate; 2 -fid; ciliate; awned; awns 1-1.2 mm long.
