Morphology General Habit
Perennial; caespitose. Cataphylls inconspicuous. Culms geniculately ascending, or decumbent, or prostrate; 5-30 cm long. Ligule an eciliate membrane; 1-3 mm long; truncate, or obtuse. Leaf-blades flat, or involute; 4-7 cm long; 1-2 mm wide. Leaf-blade venation without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface smooth.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open, or contracted; oblong, or ovate; 3-12 cm long. Primary panicle branches ascending, or spreading, or reflexed; 2-6 -nate. Panicle branches smooth. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume

Lemma surface puberulous; hairy at base. Lemma apex erose; truncate, or obtuse. Palea 1 length of lemma; 2 -veined. Palea keels smooth; eciliate.
