Description

Grevillea corrugata is a dense, spreading shrub that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in). Its leaves are 30–70 mm (1.2–2.8 in) long and deeply divided with three to seven linear lobes 10–42 mm (0.39–1.65 in) long and about 0.8 mm (0.031 in) wide. The flowers are grey, pale yellowish or greenish and arranged in groups on a rachis 20–50 mm (0.79–1.97 in) long, the pistil usually 34–38 mm (1.3–1.5 in) long and the style maroon-black, sometimes red. Flowering occurs from August to November and the fruit is a woolly-hairy, oblong follicle 13–16 mm (0.51–0.63 in) long.[2][3][4]

Taxonomy

Grevillea crowleyae was first formally described in 1993 by Peter M. Olde and Neil R. Marriott in the journal Nuytsia from specimens collected by Olde near Darkan in 1991.[4][5] The specific epithet (crowleyae) honours Valma Crowley, an amateur naturalist.[4]

Distribution and habitat

This grevillea is only known about ten plants growing in a disturbed site in gravel pit in forest at the type location in the south-west of Western Australia.[2]

Conservation status

Grevillea corrugata is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and from only one or a few locations.[6]
