Regenerates from seed.

Erect shrub 1–3 m high. Branchlets subsericeous. Leaves bifacial, entire, 1–5 cm long, 2–10 mm wide, ascending, sessile, obovate, sometimes recurved; upper and lower surfaces similar, shiny-sericeous; margins shortly and tightly involute, often also undulate; venation obscure on upper surface, the midvein and usually 2 intramarginal veins prominent below, sometimes also acutely angled lateral veins evident. Conflorescence erect, terminal or usually upper-axillary, simple or branched; unit conflorescence 3–4.5 (–7.5) cm long, cylindrical, ±synchronous; floral rachis subsericeous, occasionally sparsely so, brownish. Flowers adaxially oriented. Flower colour: perianth white to creamy white or occasionally pale yellow, sometimes with pinkish tinges; style white to creamy white. Perianth glabrous; tepals free and ascending after anthesis. Pistil 5.5–6.5 mm long, glabrous; pollen-presenter conico-cylindrical. Follicles narrowly obliquely obovoid, 9–11 mm long, smooth. 

Occurs in south-western W.A. around Burracoppin, Quairading, Kukerin and Corrigin. Usually in open heath in sand over laterite. Flowers mainly Oct.–Dec. Map 406.

W.A.: near Tammin Reserve, T.E.H.Aplin 3032 (CANB, PERTH); between Booraan and Burracopping, H.F. & M.Broadbent NSW125488 (NSW); 0.5 km E of Harrismith, M.D.Crisp 6158 et al. (CANB, NSW, PERTH); 16.5 km S of Cunderdin, B.R.Maslin 4415 (K, NSW, PERTH); 17 km S of Tammin, (Charles Gardner Flora Reserve area), R.W.Purdie 5303 (CANB).

Grevillea integrifolia can be confused with G. shuttleworthiana , but the latter species has leaves with flat (not involute) margins and wider fruit. Grevillea didymobotrya is also similar, but can be distinguished by its zygomorphic perianth with a hairy outer surface.
