Shrub to 60 cm wide; stems prostrate, short, ±underground, villous; prophylls many, linear, tomentose. Leaves: petiole 4–6 cm long, ±glabrous; lamina pinnatifid, 8–25 cm long, 5–20 mm wide; margins flat; lobes 15–35 each side, triangular, obtuse, ±flat, rusty-villous when young, glabrescent except pits. Inflorescence terminal, subtended by leaves, closely successive; involucral bracts linear-subulate; inner bracts narrowly lanceolate, to 2 cm long, dark rusty-tomentose; flowers 40–60. Perianth 39–43 mm long, pink-mauve with pale yellow limb, curled-tomentose in lower third, pubescent distally; limb 7–8 mm long, keeled, appressed-puberulous. Pistil incurved before anthesis then strongly outcurved, 43–44 (–57) mm long, cream, pilose in lower half; pollen presenter 3.5–4.8 mm long, ribbed, green. Follicles ±obovate, 5–6 mm long, with an apical tuft of long rusty hairs, glabrous below. Fig. 48C.
Known only from the type locality near Kamballup, W.A. and a small population near Brookton. Grows in spongolitic gravel, in low kwongan. Flowers Sept.–Oct. Map 350.
W.A.: near Brookton, R.Davis 1350 et al. (PERTH); near Kamballup, 1987, P.Luscombe (PERTH); near Kamballup, 20 Sept. 1988, M.Pieroni (PERTH).
Listed as 'Endangered' in the ANZECC Threatened Flora List 1997.
Easily recognised by the fruit. Unusual in having floral bracts that do not elongate as the fruits develop. Pistil very strongly incurved before anthesis, afterwards recurving strongly.
Since publication of the Flora of Australia two subspecies have been published, and the Australian Plant Census also now accepts A.R.Mast & K.R.Thiele's transfer of Dryandra to Banksia in Austral. Syst. Bot. 20: 63–71 (2007) and further in Nuytsia 16: 475 (2007). As a result this taxon is treated under Banksia ionthocarpa .
