Regenerates from seed.
Shrub 1–3 (–5) m tall. Leaves dorsiventral, 8–24 cm long, pinnatisect with 2–7 (–13) ascending linear pungent lobes 4–18 cm long; margins refracted to midvein; surfaces dissimilar, with lower surface 2-grooved, woolly in grooves. Conflorescence terminal and axillary, erect, simple or few-branched, exserted beyond leaves; unit conflorescence cylindrical, 14–21 cm long, acropetal. Flowers acroscopic. Flower colour: perianth and style cream; style-end becoming yellow. Perianth glabrous outside or with scattered short erect simple hairs denser on limb, bearded inside at base. Nectary annular. Pistil 27–30 mm long, glabrous; pollen-presenter oblique, broadly conical. Fruit an indehiscent nut, globose, 22–26 mm diam., glabrous, rugose and pitted, not viscid.
Occurs in south-western W.A., from the Murchison R. area to SE of Geraldton, and with an isolated population at Xantippe, E of Dalwallinu. Grows in open shrubland or woodland in deep yellow or white sands. Flowers Aug.–Nov.; strong sweet floral scent. Map 375.
W.A.: 25 km N & W of Yuna, J.S.Beard 6870 (PERTH); between Eradu and Indarra, C.A.Gardner 7717 (PERTH); 46.7 km N of Mingenew, A.S.George 9216 (PERTH); 29 km N of Ogilvie, M.E.Phillips 62/1314 (CANB, NSW); Xantippe, 8 km NW of Kalannie and E of Dalwallinu, W.Rogerson 302 (PERTH).
This species is recognised as 'Poorly Known' in J.D.Briggs & J.H.Leigh, Rare or Threatened Australian Plants (1995).
Occasionally confused with G. annulifera ; see under that species for differences. The indehiscent nut is unique in the genus; it falls when the seed is mature but apparently does not dehisce. The pericarp is 8–9 mm thick. Grevillea candicans differs from G. leucopteris in its short pedicels < 4 mm long, glabrous or sparsely hairy peduncles and unwinged seed (G. leucopteris has pedicels > 4 mm long, densely hairy peduncles and a narrow annular membranous wing to the seed).
The isolated population at Xantippe, about 200 km SE of the main range, has leaves with more numerous (to 13) lobes, and flowers at the lower end of the size range ('Xantippe form' of Olde & Marriott, Grevillea Book 2: 83 (top right & 65A, B), 83 (1995)).
