Straggling perennial herb, or scandent subshrub 0.5–1 (–3) m high; stems decumbent, rooting at nodes, rarely erect, sparsely appressed-hairy. Leaves opposite, with petiole 20–30 (–40) mm long; lamina ovate to lanceolate or elliptic, 2–10 (–12) cm long, (1–) 1.5–6.5 cm wide, usually rounded at base, serrate, rarely ± entire, acute to obtuse, sometimes attenuate, grey-green to yellow-green; upper surface sparsely to moderately densely appressed-strigose; lower surface with dense ± erect or semiappressed villous hairs. Capitula 1–3 (–5), 2.0–2.5 cm diam., on peduncles (0.5–) 1–6 (–12) cm long; involucral bracts 5 mm long, densely appressed-pilose; paleae oblanceolate to oblong, 5 mm long, 2 mm wide, blunt to subacute, stramineous, membranous, striate and glabrous below, green apically. Ray florets (12–) 14–16; ligule shortly 2-or 3-lobed, yellow. Disc florets c. 50; corolla yellow. Achenes obovoid, 3-or 4-angled, (2.2–) 2.5–3.0 mm long, 1.5–2.0 mm wide, apically truncate, dark grey to black, not corky, shortly and densely pilose apically, otherwise glabrous, with 1 usually oblique (rarely erect) ± glabrous fragile awn c. 2 mm long, or often awn absent.
Frequent on coastal sand, coral rubble and dunes, often a sand-binder rooting at the nodes, with Spinifex, Ipomoea and Triumfetta, but also recorded in coastal heaths and on rocky headlands.
