Aromatic annual herb (0.4–) 1.0–1.2 (–2.0) m high; stems sparsely softly pilose. Leaves all opposite, ovate (becoming narrower in inflorescence), 80–100 (–135) mm long, 35–50 (–90) mm wide, coarsely crenate, sparsely softly pilose adaxially, sparsely pilose on veins abaxially with sparse sessile golden glands between veins; petioles 15–20 mm long. Capitula hemispherical, 3–5 mm diam.; involucral bracts lanceolate, acute, green, densely pilose throughout or in upper half, with inner bracts broader; paleae stramineous, striate, laciniate and ciliate at apex, glabrous dorsally or with sparse sessile golden glands. Ray florets 2 or 3; corolla 3.5 mm long, yellow; ligule 2-lobed. Disc florets 4–6; corolla 2.5 mm long, yellow. Achenes grey to black, very finely transversely wrinkled, shortly pilose apically; ray achenes obovoid-trigonous, compressed, ±straight, 3–4 (–4.5) mm long, convex at apex, without raised corners at summit of angles, smooth (lacking tubercles), with pappus of minute (0.1–0.2 mm) scales, sometimes with 1 or 2 short (c. 0.5 mm long) soft awns; disc achenes similar but 2-angled.
Grows in sandy and loamy soils, in grassland woodland understorey and the margins of vine thickets and rainforest, from sea level in Northern Territory, but usually at 350–550 m altitude in Queensland.
