Eriachne glandulosa

HABIT Perennial. Butt sheaths persistent and investing base of culm; with compacted dead sheaths. Culms erect; 11–30 cm long; 3 -noded. Culm-internodes channelled; smooth; distally glabrous. Culm-nodes glabrous. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths loose; mostly shorter than adjacent culm internode; glabrous on surface, or pilose; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs; 1 mm long. Leaf-blades erect; flat, or involute, or convolute; 5–14.5 cm long; 2–3.3 mm wide; stiff. Leaf-blade surface scabrous; glabrous, or pilose; hairy adaxially, or on both sides. Leaf-blade margins cartilaginous. Leaf-blade apex acute.

INFLORESCENCE Inflorescence a panicle. Peduncle glabrous.

Panicle open; ovate; 2.5–6 cm long; 2.5–4 cm wide. Primary panicle branches spreading, or reflexed; 1–2 cm long. Panicle branches glandular; glabrous; glabrous in axils; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 4–8 mm long; glabrous; tip widened.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; compressed slightly; 2.5–3.3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.6–2 mm long; 1 length of upper glume; membranous; much thinner on margins; without keels; 3–5 -veined. Lower glume apex obtuse, or acute; muticous, or mucronate. Upper glume ovate; 1.6–2 mm long; 0.66 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 3–5 -veined. Upper glume apex obtuse, or acute; muticous, or mucronate.

FLORETS Fertile lemma lanceolate, or oblong; laterally compressed; 2.5–3.3 mm long; membranous; without keel; 7 -veined. Lemma lateral veins ribbed. Lemma surface pubescent; hairy below. Lemma margins involute; eciliate. Lemma apex acute, or acuminate; muticous. Palea 3–3.2 mm long; 2 -veined. Palea keels ciliate. Palea surface pubescent; hairy below. Palea apex entire.

FLOWER Lodicules 2. Anthers 3; 1.6–1.8 mm long.

FRUIT Caryopsis with adherent pericarp; obovoid; 1.5–1.7 mm long; obtuse. Embryo 0.2–0.25 length of caryopsis.

DISTRIBUTION Australasia: Australia.
