Glyceria latispicea

HABIT Perennial. Culms 50–110 cm long. Leaf-sheaths tight; tubular for much of their length; with 1 of their length closed; mostly shorter than adjacent culm internode; ribbed; glabrous on surface. Ligule an eciliate membrane; 5 mm long; acute. Leaf-blades 3–5 mm wide. Leaf-blade midrib conspicuous. Leaf-blade surface ribbed; scabrous; glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 10–15 cm long; 2 cm wide.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 20–50 mm long; scabrous.

FERTILE SPIKELETS Spikelets comprising 2–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 7–10 mm long; 0.9 length of upper glume; membranous; much thinner on margins; without keels; 3–5 -veined. Lower glume primary vein scabrous. Lower glume apex acute. Upper glume lanceolate; 8–11 mm long; 1.2–1.3 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 5 -veined. Upper glume primary vein scabrous. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; 6–9 mm long; membranous; much thinner on margins; keeled; 7 -veined. Lemma surface puberulous; hairy below. Lemma apex dentate; 2 -fid; with lobes 0.5 mm long. Palea 5–7 mm long; 2 -veined. Palea surface puberulous. Apical sterile florets resembling fertile though underdeveloped.

DISTRIBUTION Australasia: Australia.
