Perennial. Rhizomes short; pachymorph; knotty. Culms geniculately ascending; 8-14 cm long; firm. Culm-nodes pubescent. Lateral branches lacking, or sparse. Branch complement one; solitary. Leaves cauline; 6-20 per branch. Leaf-sheaths longer than adjacent culm internode; pilose. Leaf-sheath oral hairs bearded. Ligule a ciliolate membrane; 0.5 mm long; truncate. Leaf-blade base broadly rounded; with a brief petiole-like connection to sheath. Leaf-blades elliptic, or oblong; 2-4 cm long; 6-12 mm wide; light green. Leaf-blade venation with distinct cross veins. Leaf-blade surface pilose; hairy on both sides. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Synflorescence on a separate leafless culm. Inflorescence comprising only a few spikelets; comprising 1-2 fertile spikelets. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
Fertile
Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.

Lemma apex obtuse. Palea 1.2 length of lemma; 4 -veined. Palea keels winged; narrowly winged; ciliolate. Palea apex truncate. Apical sterile florets resembling fertile though underdeveloped.
