Illustrations: A.S.George, Banksia Book 136, 137, fig. 32, pl. 52 (1984); C.E.Rosser & A.S.George, Banksias II: pl. 46 (1988).

Shrub to 3 m tall, with lignotuber. Bark fissured, grey. Stems closely tomentose, glabrescent. Leaves: petiole 5–10 mm long; lamina linear, 4–13 cm long, 4–12 mm wide, obtuse; margins flat, serrate with small obtuse teeth; both surfaces tomentose, glabrescent except small pits in lower surface. Inflorescence on short, lateral branchlet on older stem, 5–9 cm long; flowers rather openly arranged; involucral bracts small, tomentose, falling early. Flowers yellow including style. Perianth 35–43 mm long including limb of 9–10 mm, glabrous. Pistil straight, 35–43 mm long, sparsely hairy in lower third, glabrous above; pollen presenter narrow, 4–5 mm long, finely ribbed. Old styles persistent and wiry; perianths usually falling. Follicles up to 70, elliptic, 15–20 mm long, 5–10 mm high, 8–12 mm wide, convex, tomentose. Seeds narrowly obovate, 19–23 mm long; seed body narrowly obovate, 9–11 mm long, 3–4 mm wide, smooth on both sides. 

Occurs between Northampton and Shark Bay, W.A. Grows in deep yellow sand on plains, in tall open shrubland. Flowers Jan.–Mar. Map 226.

W.A.: 48 km W of North West Coastal Hwy on Kalbarri Rd, A.S.George 3232 (PERTH); c. 12 km WSW of Cooloomia Stn HS, S.D.Hopper 1349 (PERTH); near Binnu, Mar. 1962, F.Lullfitz (PERTH).

Related to B. attenuata which has more deeply serrate leaves with recurved margins, much smaller, more crowded flowers and larger follicles with the old styles curled. Fire-tolerant, regenerating from lignotuber. Follicles usually opening with fire, splitting from stylar point. In the long, ribbed pollen presenter and large, openly spaced flowers the species shows a relationship to ser. Tetragonae . A presumed hybrid with B. prionotes has been recorded (Taylor & Hopper, 1988).
