Lateral branches dendroid. Bud complement 1. Branch complement several; in a horizontal line; with 1 branch dominant; thinner than stem. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs setose. Ligule a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath; petiole glabrous, or pubescent. Leaf-blades linear, or lanceolate; 2.5–5(–7) cm long; 6 mm wide; glaucous. Leaf-blade venation indistinct.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; 2.5–5 cm long. Primary panicle branches spreading; indistinct the panicle almost racemose.

Spikelets deflexed; solitary. Fertile spikelets pedicelled. Pedicels 1–6 mm long; puberulous.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 10–15 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lower glume apex acute. Upper glume oblong, or ovate; 4 mm long; 0.66 length of adjacent fertile lemma; chartaceous; without keels. Upper glume surface hirsute. Upper glume apex acute.

FLORETS Fertile lemma ovate; 6–7 mm long; keeled; 5–7 -veined. Palea 2 -veined. Palea keels contiguous above a sulcus. Palea apex ciliate.
