The species leaf-sheaths are tubular and scabrous with one of their length being closed. It eciliate membrane is 1–2 millimetres (0.039–0.079 in) long and have a glabrous surface. They also have flat leaf-blades which are 15–35 centimetres (5.9–13.8 in) long by 3–5.5 millimetres (0.12–0.22 in) wide and have scaberulous surface.[3]

The panicle itself is open and is 20–40 centimetres (7.9–15.7 in) long. The branches are distant and are 6–15 centimetres (2.4–5.9 in) long. The spikelets are oblong, solitary and are made out of 2–3 fertile florets that are 8.5–13 millimetres (0.33–0.51 in) long. Fertile spikelets are pediceled, the pedicels of which are filiform and are 2–6 millimetres (0.079–0.236 in) long. Florets are diminished at the apex.[3]

Its lemma have scabrous surface and acute apex with fertile lemma is being chartaceous, elliptic, keelless, and is 7–8.5 millimetres (0.28–0.33 in) long. Both the lower and upper glumes are elliptic, keelless, membranous, and have acute apexes. Their size is different; Lower glume is 3.5–4.5 millimetres (0.14–0.18 in) long while the upper one is 4.8–6.3 millimetres (0.19–0.25 in) long. Palea is 2-veined.
