Inflorescence a terete or slightly compressed spike, 5–12 cm long; rachis rather corky and fragmenting at maturity; sessile spikelets 6–9 mm long, the outer glume acuminate, 5–9-nerved, the inner partly adhered to the rachis, slightly shorter than the outer; sterile and fertile lemmas similar, 2–3 mm shorter than glumes; palea about half as long as lemmas; pedicellate spikelets similar to sessile ones, but glumes slightly longer, both free, and at least the inner usually shortly hooked at apex.
