Perennials. Flowering culms 20–46 cm high. Leaf blades disarticulating, involute, acute, scaberulous, glabrous or sparsely pubescent. Terminal panicles spiciform, linear, usually 3–4 cm long, 0.5–0.8 cm wide (including awns), longer than wide. Reduced panicles or solitary unmodified cleistogenes present in sheath axils. Spikelets with 3–4 florets (1 bisexual). Glumes ±equal, 2.4–5 mm long, obtuse to truncate, 4–7-nerved, pubescent with simple hairs and/or pilose with glandular hairs. Basal floret: lemma body 1.2–1.5 mm long and almost as wide, membranous to cartilaginous, not ridged at base of lobes, with margins ciliate, prominently 9 (–13)-nerved, with erect hairs exceeding the lobe bases; lemma lobes 9, longer than body to similar in length, 1.5–3.2 mm long; palea similar in length to lemma body, membranous, ciliate-scabrous towards apex on keels, with body and flaps pubescent or hirsute. Anthers 0.5–0.6 mm long.
Growing oftenabundantly on ranges, slopes and valleys in shallow and skeletal, often stonyor pebbly, redbrown fine sandy loams and desert calcareous soils, often in associationwith spinifex (Triodia species).
