White Spider Flower

Grevillea linearifolia is an erect, open shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in) and has ridged, silky-hairy branchlets. Its leaves are linear to narrowly elliptic, mostly 50–90 mm (2.0–3.5 in) long and 1–3 mm (0.039–0.118 in) wide, sometimes arranged singly, or in clusters of three. The flowers are arranged, usually in large groups held above the leaves, on the ends of branches on a peduncle 1–20 mm (0.039–0.787 in) long. The flowers are white, silky-hairy on the outside, sometimes with a faint pink tinge, and the pistil is 7–13 mm (0.28–0.51 in) long with a hooked style. Flowering mainly occurs from August to December, but also sporadically in other months and the fruit is a narrowly oval follicle 13–15 mm (0.51–0.59 in) long.

Linear-leaved grevillea grows in moist but well-drained soils, mostly sandy soils over sandstone amongst shrubby eucalypt woodland. It occurs mainly from Gosford and Putty, south to the Parramatta River and Port Jackson. There are also some disjunct populations that differ slightly from the Gosford form, but have been placed provisionally in this species. These occur near Lawson in the lower Blue Mountains, just inland from Ulladulla, and near Nowra. Records of the species from Victoria are considered to be to a range of other species, specifically G. alpivaga, G. neurophylla, G. patulifolia, G. gariwerdensis and G. micrantha.
