Eriachne bleeseri

HABIT Perennial; caespitose; clumped densely. Culms erect, or geniculately ascending; slender; 15–42 cm long; 2 -noded. Culm-internodes striate; distally pubescent; with tubercle-based hairs. Culm-nodes bearded. Lateral branches lacking. Leaf-sheaths mostly shorter than adjacent culm internode. Leaf-sheath oral hairs bearded. Ligule a fringe of hairs; 0.5 mm long. Leaf-blades curved, or flexuous; filiform; conduplicate, or involute; 10–23 cm long; 1–2 mm wide; stiff. Leaf-blade surface hispid; densely hairy; with tubercle-based hairs.

INFLORESCENCE Inflorescence a panicle. Peduncle pilose above.

Panicle contracted; lanceolate; 3–5 cm long; 0.5–1 cm wide. Primary panicle branches 0.5–1.5 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 3–15 mm long.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; compressed slightly; 6–8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus 0.3 mm long; bearded; obtuse.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume elliptic, or oblong; 3–4.3 mm long; 1 length of upper glume; membranous; much thinner on margins; without keels; 7 -veined. Lower glume apex acuminate, or cuspidate. Upper glume elliptic, or oblong; 0.5 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 7 -veined. Upper glume apex acuminate, or cuspidate.

FLORETS Fertile lemma lanceolate; laterally compressed; 6–8 mm long; membranous, or cartilaginous; without keel; 5 -veined. Lemma surface pilose; hairy below. Lemma margins involute; eciliate. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1–1.5 mm long overall. Palea 2 -veined. Palea surface glabrous. Palea apex entire.

FLOWER Lodicules 2. Anthers 3; 2.7 mm long; yellow.

FRUIT Caryopsis with adherent pericarp; ellipsoid, or oblong; 1 mm long; obtuse. Embryo 0.1 length of caryopsis.

DISTRIBUTION Australasia: Australia.
