Inflorescence typically a panicle with rather few short branches, occasionally reduced to a raceme or spike, 1–15 cm long and 1–6 cm wide, spikelets often clustered, and curved to one side, lower branches solitary. Spikelets subsessile or sessile, 9–60-fiowered, 4–35 mm long and 0.7–1.5 mm wide, commonly purplish with prominent pale margins; glumes obtuse, often splitting at apex, 1–1.8 mm long, subequal; lemmas closely overlapping, 1.5–2.5 mm long, obtuse, sometimes shallowly bilobed, nerves thickened, pale; palea subequal to or slightly longer than lemma; anthers c. 0.4 mm long.
