Grevillea neurophylla Gand. subsp. neurophylla

Illustrations: P.M.Olde & N.R.Marriott, Grevillea Book 3: 50 (top right & 35B) (1995), as Grevillea neurophylla.

Regenerates from seed and (at least sometimes) rhizomes. Presumed insect-pollinated.

Erect to spreading shrub. Branches not columnar, the foliage usually open. Leaves irregularly ascending or occasionally spreading, not or only moderately crowded, sometimes irregularly curved or wavy; longest leaves ≤ 4 cm long. Flower colour: perianth and style white to very pale pink; limb with brown hairs. Fruits 8–10 mm long. Fig. 22D–F.

Occurs in montane and subcoastal areas in south-eastern N.S.W. and montane eastern Vic. In N.S.W., S from the Brindabella Valley W of Canberra, along the western edge of the Snowy Mtns (Talbingo, Lobs Holse, Tumut area), and a longer-leaved variant on the S coast near Eden (Yambulla State Forest). In Vic., Omeo, Nunniong Plateau, Mitta Mitta, upper Genoa R. and Mt Buffalo. Grows in eucalypt woodland or open forest, often in gullies or on rocky slopes near creeks but not usually in flood-zones, in sandy granite-derived or sometimes sandstone soils. Flowers Sept.–Feb. Map 216.

N.S.W.: Kosciuszko Natl Park, c. 15 km SSE of Tumut, top of waterfall at end of Blowering Cliffs Walk, N.Taws 302 (CANB, MEL, NSW); Yumbulla [Yambulla] State Forest, Newtons Crossing Picnic area near junction of Imlay Ck, M.J.Taylor 206 & T.James (K, NSW). Vic.: sandy-rocky banks of the Snowy R., s.d. , Anon. (MEL 68654); Nunniong Plateau, Mundy Plain Track, A.C.Beauglehole 41425 (MEL, NSW); Bundarra R. Bridge on road from Omeo to Bogong High Plains, 27 km from Benambra turnoff, R.O.Makinson 910 & P.Carmen (AD, BRI, CANB, MEL, NE, NSW).

Some collections of G. neurophylla subsp. neurophylla from the Nunniong Plateau area have relatively short curved leaves and could be confused with G. alpivaga , which however, has leaves with the lower surface partly exposed. One collection from Cobungra lacks a beard inside the perianth and has a pulvinus in the beard position, and is similar in this respect to Grevillea micrantha ; however, it lacks the leaf-vein scabridity of the latter species. Occasional collections from the Mitta Mitta R. and the upper Genoa R. (the latter sympatric with subsp. fluviatilis ), closely approach subsp. fluviatilis in leaf length and crowding; fruit size for these plants is not known. Populations in N.S.W. tend to have straighter leaves and denser foliage than those in Vic.
