Regenerates from seed and/or lignotuber.
Rounded silvery to bluish grey, sometimes lignotuberous, shrub to 2 m high. Branchlets conspicuously angular, silky. Leaves secund, 4–6 cm long, pinnatisect with 5–15 lobes; lobes long-linear, 4–16, 4–12.5 cm long, 0.8–2.2 mm wide, pliable; upper surface smooth, densely subsericeous becoming glabrous; margins angularly refracted; lower surface enclosed except prominent midvein, 2-grooved, subsericeous in grooves. Conflorescence decurved, secund to cylindrical, 20–30-flowered, subsynchronous or weakly basipetal; rachis 35–60 mm long, subsericeous to pubescent. Flower colour: perianth pale pink, orange-pink or reddish pink with a greenish yellow limb; style greenish pink with green tip. Perianth sparsely subsericeous outside, denser on limb, bearded inside at curve. Pistil 22–24 mm long, glabrous. Follicle 1–13 mm long, obloid-ellipsoidal, with obscure slanting basal ridge, rugulose, glabrous.
Occurs in south-western W.A., known only from scattered populations from the Kalbarri area N to Tamala. Grows in mixed shrubland or heath, in sandy soils over laterite or limestone. Flowers (June–) Aug.–Oct. (–Dec.). Map 143.

This species is recognised as 'Poorly Known' in J.D.Briggs & J.H.Leigh, Rare or Threatened Australian Plants (1995).
Grevillea stenomera can be confused with the 'pinnate-leaved form' of G. pinaster , which differs in having shorter leaf lobes ≤ 40 mm long, and shorter floral rachises ≤ 25 mm long. Most forms of G. pinaster have most or all leaves entire. Grevillea preissii differs in its shorter, narrower leaf lobes (5–20 mm long, 0.5–1 mm wide) which are more strongly ascending than in G. stenomera and often incurved.
