Grevillea newbeyi is a species of flowering plant in the family Proteaceae and is endemic to the south west region of Western Australia. It is a dome-shaped, prickly shrub with divided leaves, the end lobes linear, rigid and sharply-pointed, and clusters of smoky pink and creamy-white flowers with a pink style.

Description

Grevillea newbeyi is a dome-shaped, prickly shrub that typically grows to 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) high and 2–3 m (6 ft 7 in – 9 ft 10 in) wide and often forms suckers. The leaves are 10–35 mm (0.39–1.38 in) long and pinnatisect, the lobes sometimes further divided, the end lobes linear, 4–25 mm (0.16–0.98 in) long, 0.8–1.4 mm (0.031–0.055 in) wide with the edges rolled under, and sharply pointed. The flowers are arranged in loose groups of up to six on the ends of branches on an elongated peduncle, the rachis 3–5 mm (0.12–0.20 in) long. The flowers are smoky pink and creamy-white with a pink, black-tipped style, the pistil 39–48 mm (1.5–1.9 in) long. Flowering occurs from June to November and the fruit is an erect follicle 11–14 mm (0.43–0.55 in) long.[2][3]

It is similar in appearance to G. patentiloba and G. tripartita.[2]
