Illustrations: P.M.Olde & N.R.Marriott, Grevillea Book 2: 22 (bottom right), 23 (13A, B) (1995).

Regeneration mode not known. Presumed insect-pollinated.

Erect to prostrate shrub (0.3–) 0.7–1 m tall. Branchlets angular, ridged, subsericeous between ridges. Leaves linear, often slightly curved, 0.8–2.5 (–3) cm long, 0.8–1.4 mm wide, crowded on suppressed or very short lateral branchlets in clusters of 3; upper surface with longitudinal veins prominent and usually granular; margins shortly twice-refracted about intramarginal vein, with the first refraction forming a short vertical wall perpendicular to the topological upper surface, the second at 90º again (leaf oblong in cross-section); lower surface usually partly exposed and subsericeous, occasionally enclosed. Conflorescence erect, terminal, sessile, regular, umbelloid, c. 8–20-flowered. Flowers adaxially acroscopic. Flower colour: perianth pale green to cream or white, with brown hairs on limb; style white to pale pink, becoming reddish later. Perianth subsericeous outside, with a scanty beard inside opposite ovary. Pistil 6.5–7 mm long; style strongly hooked in apical 3 mm, with minute hairs or papillae in apical 1 mm; pollen-presenter oblique. Follicle narrowly ellipsoidal, c. 9 mm long, faintly warty. Fig. 23B–D.

Occurs in Vic. on the Mt Buffalo massif and towards Porepunkah. Recorded for granite/slate contact zone and on slate, in Eucalyptus piperita woodland at c. 900 m alt. Flowering recorded for Oct.–Feb. Map 218.

Vic.: Mt Buffalo Plateau on flat by Ranger's cottage, R.Melville 2692 (K); c. 16 km from Porepunkah on road to Mt Buffalo, D.J.McGillivray 3188 & C.Bartlett (K, L, MEL, NSW, PERTH); Mt Buffalo at Mackies Lookout, M.E.Phillips CBG012565 (CANB); Buffalo, G.Weindorfer 585 (MEL); Mt Buffalo Natl Park, at E extremity of Hospice Plain, 21 Feb. 1963, J.H.Willis s.n.

Grevillea alpivaga is very similar, and very closely related, to G. gariwerdensis (which has a slightly longer pistil 7–8.5 mm long, less crowded leaves with the margins once-refracted, often secund branchlets, and often pedunculate conflorescences), and to G. neurophylla subsp. neurophylla (which has longer leaves, the leaf upper surface usually convex, the lower leaf surface usually fully enclosed on either side of the midvein, and shorter pedicels 3–5 mm long).
