Leaf-blade surface pilose; sparsely hairy, or moderately hairy; hairy on both sides; with tubercle-based hairs. Leaf-blade margins tuberculate-ciliate.

INFLORESCENCE Inflorescence a panicle.

Panicle capitate; ovate; 1.5–2.5 cm long; 1–1.5 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis, or with lateral stumps on axis. Panicle axis angular.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5–1.5 mm long; scabrous.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets laterally compressed; 5–6 mm long; falling entire.

GLUMES Glumes similar; subequal in width; exceeding apex of florets. Lower glume ovate; 3.5–4 mm long; 0.6–0.7 length of upper glume; chartaceous; without keels; 7 -veined. Lower glume lateral veins ribbed. Lower glume surface pilose; hairy above; with tubercle-based hairs. Lower glume margins ciliolate. Lower glume apex acute; awned; 1 -awned. Lower glume awn 3 mm long. Upper glume ovate; 5–6 mm long; 1.2 length of adjacent fertile lemma; chartaceous; without keels; 7 -veined. Upper glume surface scabrous; rough on veins. Upper glume margins ciliolate. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 3 mm long.

FLORETS Fertile lemma elliptic; 4–5 mm long; chartaceous; without keel; 5 -veined. Lemma midvein scaberulous. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn 1.5–2 mm long overall; limb scabrous. Palea elliptic; 1 length of lemma; hyaline; 2 -veined. Palea keels ciliolate. Palea surface pubescent. Palea apex dentate; 2 -fid.
