Regenerates mostly from seed, sometimes by rhizomes.
Erect shrub 1–2.2 m tall. Leaves entire, terete or rarely flat-linear to very narrowly obovate, 3–7 (–8) cm long, 0.8–1.1 mm diam. or to 1.5 mm wide if flat, with several fine longitudinal ridges (sometimes obscure), acute, pungent, either sericeous and soon glabrous, or pubescent-sericeous. Conflorescence erect, terminal on short lateral branches or axillary, enclosed within foliage, simple, umbel-like, pedunculate, obscurely basipetal to subsynchronous; floral rachis < 2 mm long. Flower colour: perianth green in bud, becoming greenish white to cream [greener towards base?]; style white, sometimes pinkish with age. Perianth bearded inside; tepals independently recoiled after anthesis. Pistil 10–12.5 mm long; style exserted from late bud; pollen-presenter oblique, convex. Follicles obloid-ellipsoidal, (6.5–) 9–13 mm long, smooth to granular-rugulose, often with a blunt transverse ridge on each flank, glabrous, sometimes glaucous, sometimes slightly viscid.
Widespread in inland W.A., from near Cosmo Newbery and Wiluna to Perenjori, S to Ravensthorpe, and E to Queen Victoria Spring. Usually found in shrubland. Flowers (May–) July–Sept. Map 175.
W.A.: 10 km SSE of Perrinvale HS, R.J.Cranfield 7146 (CANB, PERTH); 2.5 km NE of Comet Vale townsite and 2 km N of edge of L. Goongarrie, A.V.Milewski 1087 (CANB, PERTH); 42.7 km E of Sandstone, B.H.Smith 401 (CANB, MEL, NSW, PERTH).
Superficially similar to G. hakeoides which has leaves with two grooves only (either on the lower surface or almost lateral), and markedly rugose fruits with a thin wall c. 0.5 mm thick (0.6–3 mm thick in G. acacioides ). Grevillea brachystachya also has some similarity, but has much more robust and larger flowers (pistils 12–17 mm long) with hairs on the outer surface of the perianth.
