Eriachne pallescens R.Br.

Perennial plants 23–105 cm high, mostly glabrous on culms and foliage; base knotty or slightly thickened, sparsely pubescent. Culms usually branched; nodes glabrous. Leaves sometimes hispid with tubercle-based hairs near ligule; sheaths to half as long as culm internodes; blade to 18 cm long, to 3.5 mm wide, scabrous, sometimes hispid. Panicles open, sometimes drooping, 6–15 cm long, 3–9 cm wide. Spikelets often cleistogamous. Glumes obliquely attached (distant by c. 0.5 mm), equal to slightly unequal, 2.5–6.3 mm long, muticous, 9 (–13)-nerved, smooth or sometimes scabrous, glabrous (rarely upper glume or both glumes pilose to sparsely pubescent). Florets slightly shorter than glumes or exceeding them by 0.6–1 mm. Callus entirely bearded, rarely with glabrous tip. Lemma 3–5 mm long, awned, cartilaginous to indurated, faintly few–7-nerved, without grooves, hirsute with appressed hairs over entire back or sometimes glabrous and scabrous near apex; awn 1.5–8 mm long. Palea entire or bifid into two awns 0.3–3.3 mm long, hirsute or pubescent on entire body or glabrous in upper c. third. Caryopsis 1.8–3.3 mm long.
