Spikelets in lax almost digitate spikelets, sessile and on the end of primary (and sometimes secondary) branches, 7–15 per cluster, linear-lanceolate, 6.5–19 mm long, 1.2–1.9 mm wide, rachilla straight or curved.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reddish-brown with a wide uncoloured marginal border, ovate-elliptic, 2.4–3.5 mm long, 1.3–1.7 mm wide, closely overlapping, keel greenish, apex rounded to acute

Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 1.7–2.6 mm long.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers 0.9–1.7 mm long
Morphology Reproductive morphology Fruits
