Description

Grevillea corrugata is a dense shrub typically 0.5–2.5 m (1 ft 8 in – 8 ft 2 in) high and 1.5–2 m (4 ft 11 in – 6 ft 7 in) wide. Its leaves are usually deeply divided, 40–60 mm (1.6–2.4 in) long and 90 mm (3.5 in) wide in flattened outline. The leaves have three to five sharply-pointed, linear lobes usually divided again, the ultimate lobes 15–35 mm (0.59–1.38 in) long and 0.7–0.8 mm (0.028–0.031 in) wide. The flowers are white to cream-coloured and arranged in more or less sessile, spherical to oval groups on a rachis 8–20 mm (0.31–0.79 in) long, the pistil 3.5–4.0 mm (0.14–0.16 in) long. Flowering has been observed in August and September and the fruit is a wrinkled, oblong follicle 7–11 mm (0.28–0.43 in) long.[2][3][4]

Taxonomy

Grevillea corrugata was first formally described in 1993 by Peter M. Olde and Neil R. Marriott in the journal Nuytsia from specimens collected by Olde near Bindoon in 1992.[4][5] The specific epithet (corrugata) means "strongly wrinkled", referring to the surface of the fruit.[4]

Distribution and habitat

This grevillea is only known from the type location where it grows in disturbed eucalypt woodland.[2]

Conservation status

Grevillea corrugata is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and "Threatened" by the Western Australian Government Department of Parks and Wildlife.[3][6][7]
