Inflorescence contracted at first but becoming open, usually <40% of plant height, to 27 cm long, 3–12 cm wide; branches slender, [spreading? - to be checked]; primary branches naked for up to 2.2 cm, glabrous, scaberulous; pedicels [to be checked] mm long. Spikelets to 4.5 mm long, c. 1 mm wide, florets 5–7; rachilla disarticulating or persistent, weakly flexuose, with apical vestige. Glumes 1.3–1.8 mm long, subequal or the upper longer.
