Grevillea makinsonii is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub with egg-shaped to more or less spatula-shaped leaves, and clusters of cream-coloured to pale yellow flowers.
Grevillea makinsonii is an erect shrub that typically grows to a height of 0.6–1.6 m (2 ft 0 in – 5 ft 3 in) high. The leaves are egg-shaped with the narrower end towards the base to more or less spatula-shaped, 10–30 mm (0.39–1.18 in) long and 3–8 mm (0.12–0.31 in) wide. The flowers are arranged in conical clusters 30–60 mm (1.2–2.4 in) long and are glabrous and cream-coloured to pale yellow, the pistil 5.5–6 mm (0.22–0.24 in) long. Flowering occurs from July to October, and the fruit is a wrinkled, oval follicle about 6 mm (0.24 in) long.[2][3]
Grevillea makinsonii was first formally described in 1986 by Donald McGillivray in his book New Names in Grevillea (Proteaceae) from specimens collected near Arrino in 1969.[4] The specific epithet (makinsonii) honours Robert Owen Makinson.[5]
This grevillea grows in heath on sandplains in the area around Arrino, Three Springs and Eneabba in the Avon Wheatbelt, Geraldton Sandplains bioregions of south-western Western Australia.[2][3]
Grevillea makinsonii is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[6]
