Fl. Australia 44A: 386 (2009) APNI

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: vulnerable (v)

Culms erect, 100–170 cm long, smooth and glabrous. Leaves glabrous; blade flat, 15–30 cm long, 2–5(–8) mm wide; ligule membranous, truncate or erose, 2–5 mm long. Inflorescence narrowly ovate to loosely contracted, sometimes interrupted, 25–35 cm long; glumes acute to acuminate or the lower one sometimes obtuse and mucronate, 3.5–6 mm long, subequal or the upper longer by up to 1.5 mm; lemma equal to upper glume or exceeding it by 0.5 mm, smooth to scabrous, particularly in upper half; awn inserted about 0.5 mm from lemma apex, 10–16 mm long, sinuous, the column hardly differentiated, not or barely twisted at maturity. Flowers Oct.–Dec. (3 records)

EGL. Also NSW. Apparently uncommon, and known only from near-coastal areas of east Gippsland (near Lake Corringle, south of Orbost; Genoa, Mallacoota areas). Habitat incompletely known, recorded from a rocky gully-head in lowland forest near Genoa.

In the weakly twisted, sinuous awn resembling D. inaequiglumis (generally a subalpine species), but a much more robust plant with a more contracted, floriferous inflorescence and the lemma more consistenly exceeding the glumes. It is also similar to D. sieberiana but differs in the awn column only being slightly twisted and by the glabrous or minutely scabrous culms.
