Leptaspis banksii R.Br.

Culms 30–100 cm high. Leaves: ligule 0.4–0.5 mm long; pseudopetiole 10–50 mm long, ± folded, hairy adaxially and sometimes also, but less so, on outer surface; blade lamina narrowly elliptic to slightly lanceolate or oblanceolate, (7–) 9.5–39 cm long, 9–40 mm wide, finely hairy along nerves adaxially (but apparently mostly abaxial from twisting of pseudopetiole), scabrous on margins. Panicles (10–) 13–30 (–40) cm long, primary branches solitary, erect to spreading, mostly 1–6 cm long, with short uncinate hairs on all axes. Male spikelets: glumes ± equal or sometimes unequal in length, broadly ovate to triangular, 1–1.8 mm long, cuspidate with mucro to 0.5 mm long, 1–3-nerved, sparsely hairy; lemma broad, with uncinate hairs and recurved mucro; anthers 1.3–1.5 (–2 5) mm long. Female spikelets to 5.5 mm long; glumes (1–) 1.5–2.4 mm long, with sparse uncinate hairs; lower glume 1–3-nerved; upper glume (1–) 3-nerved; lemma (3–) 4–5.5 mm long, muticous, strongly 7-nerved with nerves forming pronounced ridges connected by transverse nervelets on outside of utricle, puberulous with uncinate hairs. Staminodes 6, minute, at base of ovary.

Grows in rainforest or vine forests, in dark sandy loam or red clay soils, on granite and along dry creek beds, above creeks or on hill slopes.
