Dryandra armata R.Br., Trans. Linn. Soc. London 10: 213 (1810)

Josephia armata (R.Br.) Kuntze, Revis. Gen. Pl. 2: 578 (1891). T: King George Sound, [W.A.], Dec. 1801, R.Brown Iter Austral. 3416 ; holo: BM; iso: K, MEL.

Shrub to 1.5 m, with or without lignotuber, often sprawling. Stems hirsute and pubescent, glabrescent. Leaves: petiole 3–5 mm long, glabrescent; lamina pinnatifid, narrowly cuneate to narrowly obovate, linear, oblong or elliptic, 2–8 cm long, 8–25 mm wide, acute, pungent, tomentose only in pits; margins flat, deeply serrate; lobes 5–13 each side, obliquely triangular, slightly falcate, pungent, to 9 mm long. Inflorescence on short branchlet; involucral bracts ovate to linear, obtuse, to 15–25 mm long, tomentose, pubescent or hirsute in upper half, glabrous or almost so below; floral bracts glabrous; flowers c. 45–70 per head. Perianth ±straight, 25–39 mm long, yellow, with short crisped hairs immediately above base, hirsute distally; limb glabrous in upper ½ or throughout; limb 4–5 mm long. Pistil straight to curved, 28–42 mm long, cream to yellow, hirsute in lower 1/4–1/3; pollen presenter narrow, 2.5–4.5 mm long, ribbed. Follicles obliquely ovate, 9–10 mm long, hirsute at base. 

A widespread, variable species in W.A., occurring from Mt Lesueur to Albany and east to Israelite Bay. 

Forms a close-knit group with D. arborea , D. hirsuta and D. purdieana . Also similar to D. borealis q.v. Two varieties are recognised but a more detailed study is needed.

Since publication of the Flora of Australia the Australian Plant Census accepts A.R.Mast & K.R.Thiele's transfer of Dryandra to Banksia in Austral. Syst. Bot. 20: 63–71 (2007). As a result this taxon is treated under Banksia armata .
