It have a ligule that goes around the ciliolate membrane and is 0.2–0.4 millimetres (0.0079–0.0157 in) long. Leaf-blades are flat and are 10–25 centimetres (3.9–9.8 in) long and 1.5–3 millimetres (0.059–0.118 in) wide. The panicle is capitated, oblong, ovate and inflorescenced with a diameter being 1–3 centimetres (0.39–1.18 in) by 0.5–0.7 centimetres (0.20–0.28 in). Spikelets are oblong, solitary, and are 4–7 millimetres (0.16–0.28 in) long with pedicelled fertile ones. Sterile spikelets grow in pairs and carry 2–3 fertile florets. Both upper and lower glumes are 4–7 millimetres (0.16–0.28 in) long and are also ovate, membranous, glaucous, with a single keel and vein, and with acuminated and muticous apexes. Fertile lemma is ovate, membranous, and is 4–6 millimetres (0.16–0.24 in) long. Flowers have three stamens, two stigmas, and are hairy. The fruits have caryopses which have an additional pericarp, a hairy apex, and elliptic hilum.[1]
