Ligule a fringe of hairs. Leaf-blades flat, or involute; 5–10 cm long; 1.5–2.5 mm wide; stiff. Leaf-blade midrib indistinct. Leaf-blade apex acute, or acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; linear; 4 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs; pubescent.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; tip discoid.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 6 mm long; falling entire. Spikelet callus bearded; base obtuse; attached obliquely. Spikelet callus hairs 0.25 length of spikelet.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 5 mm long; 0.8 length of spikelet; chartaceous; without keels; 3 -veined. Lower glume lateral veins ribbed. Lower glume surface glabrous. Lower glume apex truncate. Upper glume lanceolate; 6 mm long; 1 length of spikelet; coriaceous; with membranous margins; 5–7 -veined. Upper glume lateral veins ribbed. Upper glume surface pubescent; hairy below; with marginal tufts of hair. Upper glume apex acuminate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 4 mm long; 0.66 length of spikelet; chartaceous; 3 -veined; eciliate on margins; truncate. Fertile lemma lanceolate; 4 mm long; hyaline; without keel; 3 -veined. Lemma apex obtuse. Palea with auriculate flaps; 1.1 length of lemma; hyaline; 2 -veined; without keels. Palea apex acute.
