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]

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]
