Grevillea fililoba

Grevillea fililoba is a spreading shrub, typically up to about 1.5 m (4 ft 11 in) high and 3 m (9.8 ft) wide with soft, dense foliage. The leaves are 20–45 mm (0.79–1.77 in) long and divided, the lobes narrowly linear, sometimes curved, 2–20 mm (0.079–0.787 in) long and 0.3–0.7 mm (0.012–0.028 in) wide. The upper surface of the leaves is more or less glabrous, the edges rolled under obscuring most of the lower surface. The flowers are arranged in groups of twelve to thirty along a rachis 18–30 mm (0.71–1.18 in) long and are pink to bright red with a pink, green-tipped style, the pistil 24–28 mm (0.94–1.10 in) long. Flowering occurs from July to September and the fruit is a triangular follicle about 13 mm (0.51 in) long.^[3][1]

This grevillea was first formally described in 1986 by Donald McGillivray who gave it the name Grevillea thelemanniana subsp. fililoba in his New Names in Grevillea (Proteaceae) from specimens collected by Robert Royce in 1986.^[4] In 1994, Peter M. Olde and Neil R. Marriott raised the subspecies to species level as Grevillea fililoba in The Grevillea Book.^[5] The specific epithet (fililoba) means "thread-lobed".^[6]

This grevillea grows in a range of habitats and is found east of Geraldton in the catchments of the Greenough and Irwin Rivers in the Geraldton Sandplains biogeographic region of south-western Western Australia.^[3][1]
