Banksia integrifolia L.f., Suppl. Pl. 127 (1782)

Sirmuellera integrifolia (L.f.) Kuntze, Revis. Gen. Pl. 2: 582 (1891); Isostylis integrifolia (L.f.) Britten, in J.Banks & D.Solander, Illustr. Austral. Pl. Cook's Voy. 3: 83 (1905). T: Botany Bay, [N.S.W.], Apr.–May 1770, J.Banks ; lecto: LINN 162.5, fide A.S.George, Nuytsia 3: 277 (1981); isolecto: B, BM, C, K, MEL, NSW, US.

Tree to 25 m tall, fire tolerant. Bark roughly tessellated. Stems pubescent and pilose, glabrescent, pale brown. Leaves in whorls of 3–5; petiole 4–10 mm long; lamina narrowly obovate to narrowly elliptic, 4–20 cm long, 10–26 mm wide, obtuse or emarginate; margins not or slightly recurved, entire; upper surface dull green, pubescent, glabrescent; lower surface closely white-woolly. Inflorescence 5–12 cm long; involucral bracts 2–10 mm long, tomentose. Flowers pale yellow, including styles. Perianth 22–25 mm long including limb of 3.5–4.5 mm, closely pubescent outside, glabrous inside. Pistil straight or slightly curved, 27–32 mm long, glabrous; pollen presenter 0.5–1 mm long, scarcely thickened. Old flowers soon falling. Follicles up to c. 60, narrowly elliptic, 7–15 mm long, 3–10 mm high, 3–6 mm wide; valves semi-elliptic, smooth, tomentose, glabrescent. Seed obovate, 10–20 mm long; seed body ±cuneate, 6–10 mm long, ±smooth. 

Widespread along the east coast and inland to the nearby mountains, from Proserpine, Qld, to Port Phillip Bay, Vic. 

Follicles usually opening when mature, within a year of flowering. Related most closely to B. aquilonia from northern Qld which differs mainly in its scattered (or alternate) but crowded leaves, and to B. dentata which has large, alternate, dentate leaves and occurs across tropical Australia.

There are three subspecies.
