Description

[edit]

The plant is perennial and caespitose with erect culms that are 20–60 centimetres (7.9–23.6 in) long. They are also clumped and have light brown coloured butt sheaths. The ligule is going around the eciliate membrane with the leaf sheaths being open and hairy. Leaf-blades are filiform, conduplicate, light green in colour, and are 0.3–0.7 centimetres (0.12–0.28 in) broad. They also have smooth surface and peduncle. The panicle is linear, open, inflorescenced and is 6–14 centimetres (2.4–5.5 in) long.[2]

Spikelets are elliptic and solitary with pedicelled fertile spikelets that carry 4-6 fertile florets. The main panicle branches are hairy. The glumes are chartaceous, lanceolate, and keelless. They also have acute apexes, while only the upper glume is sized 2.9–4 millimetres (0.11–0.16 in). Fertile lemma is 2.5–4.7 millimetres (0.098–0.185 in) long and is also chartaceous, lanceolate, keelless, and are of the same colour as leaf blades. The main lemma have an acuminate apex and carries one awn that is 0.3–0.8 millimetres (0.012–0.031 in) long. Flowers have three stamens while the fruits are caryopses with an additional pericarp and linear hilum.[2]
