Regenerates from seed and epicormic buds.
Spindly erect shrub or small tree 2–10 (–15?) m tall. Leaves dorsiventral, entire, narrowly ovate to elliptic, 6–20 cm long, 10–65 mm wide; margins flat; surfaces similar, pubescent tending more appressed below. Conflorescence terminal, usually 2–8-branched from near base; primary peduncle ±erect but branches usually decurved to pendulous; unit conflorescence decurved to pendulous, cylindrical, 6–18 cm long, subsynchronous to weakly basipetal. Flowers transversely oriented with sutures extrorse. Flower colour: perianth and style creamish to greenish white. Perianth subsericeous to tomentose outside, glabrous inside. Nectary arcuate. Pistil (10–) 14–16.5 mm long, glabrous; pollen-presenter an erect narrow cone. Follicle subglobose to subovoid, 24–40 mm long, rugose, glabrous. Fig. 33E–G.
Occurs in north-eastern Qld from Jericho and Torrens Ck to Normanton and Cape York; also in Papua New Guinea. Grows in a wide range of habitats including seasonally dry open forest, woodland, savanna, sometimes in coastal dune heath, in light sandy or gravelly often granitic soils, sometimes in low waterlogged areas. Flowers mainly Apr.–Aug. Map 368.
Qld: Mt Molloy, L.J.Brass 2506 (A n.v. , B n.v. , BISH n.v. , BRI, MEL); 43.5 km NNE of Normanton Rd towards Lotus Vale Stn, P.Ollerenshaw 1459 (BRI, CANB, NSW); 9.7 km E of Torrens Creek Township, N.H.Speck 4557 (BRI, CANB).
Grevillea glauca shows little variation over most of its range. Occasional specimens from the Stannary Hills near Herberton have unusually small flowers (pistils c. 10 mm long); it is unclear whether these represent a consistent population; plants with normal-sized flowers (pistils ≥ 14 mm long) are common in the same general area.
The timber has been used in boomerang manufacture, and the open gaping fruits were once used as improvised clothes pegs.
