Description

Grevillea quinquenervis is an erect, dense shrub that typically grows to a height of 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) high and has angular, hairy branchlets. Its leaves are more or less linear to oblong or narrowly egg-shaped with the narrower end towards the base, 15–60 mm (0.59–2.36 in) long and 1.5–8 mm (0.059–0.315 in) wide with the edges strongly curved downwards or rolled under. The upper surface of the leaves usually has 5 prominent, longitudinal veins. The flowers are arranged on the ends of branches or short side-branchlets in groups of 6 to 20 and are pale to deep pink, the pistil 9.5–12 mm (0.37–0.47 in) long. Flowering mainly occurs from October to December and the fruit is an oval to oblong follicle 13–15 mm (0.51–0.59 in) long.[2][3]
