Shrub to 3 m tall, with lignotuber. Bark smooth, grey-brown. Stems tomentose, rusty becoming grey. Leaves alternate; petiole 2–5 mm long; lamina oblong to obovate, commonly 5–11 cm long, 1.5–2 cm wide, obtuse or truncate; margins slightly recurved, commonly serrate with teeth 1–2 mm long; upper surface densely rusty-tomentose, glabrescent; lower surface tomentose, with nerves glabrescent and pits woolly. Inflorescence terminal to a 1–5-year-old branchlet, 5–15 cm long; involucral bracts densely tomentose, persistent. Flowers pale yellow, often with blue-grey tinge; style cream. Perianth 21–26 mm long including limb of 4 mm, pubescent-hirsute outside, glabrous inside. Pistil straight, 20–28 mm long, glabrous; pollen presenter narrowly ovoid, 0.7–0.8 mm long. Old flowers soon falling. Follicles up to 80, narrowly elliptic, 10–18 mm long, 2–7 mm high, 3–7 mm wide; valves semi-circular, smooth, velvety, glabrescent. Seed obovate, 12–18 mm long; seed body oblong to semi-elliptic, 7–11 mm long, 3–7 mm wide, smooth or slightly rugose.
Occurs in Qld and N.S.W., between Bundaberg and Ulladulla, mostly near the coast, but also on the Blackdown Tableland, Qld. On flats and swamp margins in sandy clay or clay-loam, in open forest, woodland and tall shrubland (Wallum); also on sandstone or granite ridges in open forest. Flowers Mar.–June. Map 181.

Fire-tolerant, sprouting from the lignotuber. Follicles typically open with fire. Related to B. robur which has much larger leaves, metallic green buds, and flowers with a very short indumentum. Also related to B. plagiocarpa which has longer, coarsely serrate to entire leaves, blue-grey buds and obliquely triangular follicles. Var. minor is not accepted (George, 1996; Thiele & Ladiges, 1996). In cultivation some Qld forms produce multiple flower spikes on lower stems.
