Regenerates from seed.

Robust erect shrub 0.6–2.5 m tall. Leaves entire, elliptic to obovate, 2–6.5 cm long, 7–20 mm wide; margins flat to recurved, ciliate; upper surface with a sparse indumentum, otherwise smooth; lower surface glabrous. Conflorescence terminal on lateral branchlets, simple, erect to decurved, secund, umbelloid, usually 13–18-flowered, subsynchronous; floral rachis 1–2 mm long, villous. Flowers adaxially acroscopic. Flower colour: perianth light orange in bud, yellow at anthesis, then deepening to orange again; style-end yellow becoming red. Perianth sparsely pubescent to pilose outside, bearded inside; tepals with a prominent medial ridge. Pistil (6–) 7–8 mm long; ovary shortly stipitate villous; style sparsely villous, scarcely exceeding perianth after release of style-end; pollen-presenter lateral. Follicle ovoid, c. 15 mm long, pubescent, longitudinally ridged. 

Occurs in south-western W.A., in the Helena and Canning R. areas E and SE of Perth. Grows in open shrubby eucalypt woodland or forest in gravelly or clay-loam soils. Flowers July–Nov. Map 304.

W.A.: S side of Mundaring Weir, A.S.George 11656 (CANB, PERTH); bank of Canning R. near Gleneagle, 30 May 1963, A.H.Larner 3 (PERTH); [loc. variously as 'montium Darling Range' or 'Glen Forrest'], Aug. 1901, E.Pritzel 517 [also as L.Diels 3697 ] (A n.v. , AD, B n.v. , E, G, GH n.v. , K, NSW, P n.v. , PERTH).

This species is recognised as 'Rare' in J.D.Briggs & J.H.Leigh, Rare or Threatened Australian Plants (1995).

Grevillea pimeleoides differs from G. centristigma in its usually 13–18-flowered unit conflorescences, the obovate pollen-presenter with its base concurrent with the style or nearly so, and the stigma being near-basal on the pollen-presenter face. Grevillea centristigma typically has unit conflorescences 5–8-flowered, the pollen-presenter nearly circular, its base clearly not concurrent with the style, and the stigma central or nearly so (occasionally tending basal). There is a tendency for G. pimeleoides to have larger leaves, and a slightly longer pistil, although there is some overlap on both features among specimens in the NW of the range of G. centristigma .
