Leaf-sheaths tubular for much of their length; with 0.5–0.66 of their length closed; with infolded margins; glabrous on surface. Ligule a ciliolate membrane. Leaf-blades filiform; conduplicate; 0.2–0.3 mm wide; stiff. Leaf-blade venation comprising 5–7 vascular bundles; with 3 inner ridges; with sclerenchyma strands below veins; with subepidermal sclerenchyma free from veins.

INFLORESCENCE Inflorescence a panicle. Peduncle pubescent above.

Panicle open; oblong; dense; 3–5 cm long. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets with diminished florets at the apex. Spikelets oblong; laterally compressed; 6.8–7.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 3.4–4.8 mm long; 0.75 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma oblong; 4.6–5.5 mm long; chartaceous; without keel; 5 -veined. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1.5–2 mm long overall. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 2.5–3 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; ellipsoid. Hilum linear. Disseminule comprising a caryopsis and palea.
