Description
Grevillea corrugata is a dense shrub typically Template:Cvt high and Template:Cvt wide. Its leaves are usually deeply divided, Template:Cvt long and Template:Cvt wide in flattened outline. The leaves have three to five sharply-pointed, linear lobes usually divided again, the ultimate lobes Template:Cvt long and Template:Cvt wide. The flowers are white to cream-coloured and arranged in more or less sessile, spherical to oval groups on a rachis Template:Cvt long, the pistil Template:Cvt long. Flowering has been observed in August and September and the fruit is a wrinkled, oblong follicle Template:Cvt long.[1][2][3]
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.[3][4] The specific epithet (corrugata) means "strongly wrinkled", referring to the surface of the fruit.[3]
Distribution and habitat
This grevillea is only known from the type location where it grows in disturbed eucalypt woodland.[1]
Conservation status
Grevillea corrugata is listed as Endangered on the IUCN Red List of Threatened Species, as well as under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and "Threatened" by the Western Australian Government Department of Parks and Wildlife. It has a small and highly restricted distribution with an estimated extent of occurrence of 394km² and a population of approximately 330 mature individuals. Threats to this species include pollution from chemical spraying, competition with invasive weeds and habitat clearing and fragmentation for agriculture.[5][2][6][7]
