Distinguishing characters include leaf sheaths longer than internodes; ligule
ciliate; panicle spiciform continuous; spikelets serrated in outline, often
olive-green; florets loosely imbricate, the lemma and palea divergent at
maturity; rachilla, glumes, lemmas and paleas persistent; glumes unequal,
separated by an internode at their points of attachment; lower and upper lemmas
in spikelet unequal in length, with often obscure or absent lateral nerves;
palea dividing into two equal parts, its keels almost smooth, and its flaps wider
than its body; anthers green, terminally exserted; caryopsis strongly
compressed, 3–4-angled, stipitate; pericarp free, mucilaginous, partly shedding
the polished, striate, naked grain.
distribution is in eastern Qld inland from Townsville S to near Inverell in
northern N.S.W. In deep or skeletal, often rocky, red or brown loams; in
association with sandstone gorges and ridges, basaltic outcrops, and limestone
boulders; also in disturbed clearings and roadsides.; flowers Dec.-July; fruits
