Leaf-sheaths smooth or scaberulous, glabrous on surface. Leaf-sheath auricles
absent. Ligule a fringe of hairs, 1–1.3 mm long. Leaf-blades straight, filiform
or linear, flat or conduplicate, 9–15 cm long, 1–2 mm wide. Leaf-blade surface
Inflorescence compound, a panicle. Panicle linear, dense, 14–19 cm long, 1–1.5
Spikelets pedicelled. Fertile spikelets many flowered, with at least 2 fertile
florets (11–18), comprising 11–18 fertile floret(s), with diminished florets at
the apex, lanceolate, laterally compressed, 17–25 mm long.
Glumes similar, thinner than fertile lemma. Lower glume lanceolate,
cartilaginous, keeled, 1-keeled, 5–7 -nerved. Lower glume surface glabrous.
Lower glume apex muticous or mucronate. Upper glume orbicular to oblate, 7–9 mm
long, scarious or cartilaginous, keeled, 1-keeled, 5–7 -nerved. Upper glume
surface smooth or asperulous, glabrous. Upper glume apex entire, muticous or
Fertile lemma 7–8 mm long, without keel, 9 -nerved. Lemma surface indumented.

mm long overall. Palea apex dentate. Lodicules present. Anthers 3.
Distribution: Northern Territory.
Central Australia South.
Known from only two collections.
Distinguishing characters include the
lanceolate, closely flowered, long spikelet distinctively tapered to the apex;
almost entire, shiny lemma with unequal lobes; dense, linear panicle; partly
hairy, relatively short palea with broadly winged keels and broad flaps;
usually long bearded mouth and hairy blades, and non-resinous foliage.
Central Australia. In mountain ranges; flowers May-June.
