Derivation: L. mons,

Perennial. Culms erect, 5–45 cm tall, 2–3 -noded. Leaf-sheaths hairy. Ligule a
fringe of hairs. Leaf-blades involute, 7–15 cm long, 1–2 mm wide. Leaf-blade
surface indumented.

Inflorescence solid, a panicle. Panicle lanceolate or ovate, 1–4 cm long.

Spikelets pedicelled. Fertile spikelets many flowered, with at least 2 fertile
florets (4–6), comprising 4–6 fertile floret(s), with diminished florets at the
apex, cuneate, laterally compressed, 7–11 mm long.

Glumes. Glumes
similar, thinner than fertile lemma. Lower glume lanceolate, membranous,
without keels, 9 -nerved. Upper glume lanceolate, 8–11 mm long, membranous,
without keels, 9 -nerved.

Fertile lemma 1.2–2.6 mm long, without keel, 9 -nerved. Lemma surface glabrous.
Lemma apex lobed, awned, 3 -awned. Median (principal) awn from a sinus, 6–7 mm
long overall, with a twisted column. Lateral lemma awns present. Lodicules
present. Anthers 3. Grain 1.2–1.4 mm long.

Notes. R.
could be confused with several species: a) from R. tenuius
it is distinct by the formation of distinct little tussocks; b) from R.
it differs by the setae being shorter than the lemma lobes, and
from c) R. geniculatum it differs by the lemma awn being longer than the
lemma lobe setae. It is most readily characterised by the caespitose habit, the
fine leaves, and the small spikelets.

from the Queensland border to Horsham in Victoria, altitude 60–1400 m, common
in heathland, on shallow soils over sandstone, also in grassland on deeper,
heavier soils. Flowers Nov. to Dec.
