It sterile florets are barren, oblong, growing in a clump and are 4.5–6.5 millimetres (0.18–0.26 in) long. The species' fertile lemma is chartaceous, keelless, oblong and is 8–11 millimetres (0.31–0.43 in) long. Both lower and upper glumes are chartaceous, elliptic and keelless with acute apexes. Their size is different though; Lower glume is 7–12 millimetres (0.28–0.47 in) long while the upper one is 9–15 millimetres (0.35–0.59 in) long.
