Descriptions

Morphology General Habit
Perennial; caespitose. Culms erect; 15-45 cm long. Leaves mostly basal. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane. Leaf-blades erect; lanceolate; 2-7(-17) cm long; 2-4 mm wide; stiff.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; straight; bilateral; 3-6 cm long; bearing few fertile spikelets; bearing 1-4 fertile spikelets on each. Spikelet packing broadside to rhachis; lax; 2 -rowed. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 20-30 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 20-30 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 lanceolate; 4-8 mm long; 1 length of upper glume; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume lanceolate; 4-10 mm long; 0.6-0.9 length of adjacent fertile lemma; membranous; without keels; 7 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 7-11 mm long; membranous; without keel; 7 -veined. Lemma apex acute; awned; 1 -awned. Principal lemma awn apical; 4-8 mm long overall. Palea oblong; 1 length of lemma. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3. Ovary with a fleshy appendage below style insertion; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex; apex fleshy. Hilum linear.
