Inflorescences terminal, open or contracted panicles, with evident rachiseswith numerous subverticellate branches that terminate in 1-3 short rames; rames with slender internodes and 2-5 sessile-pedicellate homogamous spikelet pairs; disarticulation in the rames, below the sessile spikelets. Spikelets usually lanceolate. Glumes equal, chartaceous, often pilose, scarcely keeled, with several raised veins, acute; calluses glabrous or densely hairy; lower florets usually staminate, unawned; upper florets bisexual; upper lemmas bilobed, with a geniculate awn; anthers 3. x = 10. Pedicels slender, not fused to the rames axes.
