Morphology General Habit
Perennial; mat forming, or caespitose. Culms decumbent, or rambling; weak; 10-40 cm long. Ligule an eciliate membrane. Leaf-blades filiform; 2-10(-17) cm long; 1-2 mm wide; aromatic.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle, or composed of racemes; comprising 3-30 fertile spikelets. Panicle contracted; linear, or oblong; 1-3.5 cm long; bearing few spikelets. Racemes single; lanceolate; paucilateral; 1-2 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
