Leaf-blades linear, or lanceolate; flat, or involute; 5–15 cm long; 2–10 mm wide; stiff; glaucous. Leaf-blade surface ribbed; scabrous. Leaf-blade apex acute; muticous, or pungent.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; smoothly terete; bilateral; 4–20 cm long. Rhachis fragile at the nodes; subcylindrical and excavated; glabrous on surface; glabrous on margins. Spikelet packing adaxial; regular; 2 -rowed. Rhachis internodes oblong; 3–7.5 mm long. Rhachis internode tip oblique; flat.

Spikelets sunken; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; dorsally compressed; 10–14 mm long; falling entire; deciduous with accessory branch structures.

GLUMES Glumes one the lower absent or obscure; exceeding apex of florets; firmer than fertile lemma. Upper glume lanceolate; 10–14 mm long; 2–3 length of adjacent fertile lemma; coriaceous; without keels; 8–12 -veined. Upper glume lateral veins ribbed. Upper glume apex attenuate; muticous, or awned; 1 -awned. Upper glume awn 0–5 mm long.

FLORETS Fertile lemma ovate; 4–5.5 mm long; membranous; without keel; 3 -veined. Lemma lateral veins extending close to apex. Lemma surface puberulous; hairy below. Lemma apex obtuse. Palea 2 -veined.

FLOWER Lodicules 2. Anthers 3; 1.5–2.5 mm long. Stigmas 2.
