(''hakeoides'') means "'' Hakea''-like". In 1986 Donald McGillivray described two subspecies in his book, ''New Names in Grevillea (Proteaceae)'', and the names are accepted by the Australian Plant Census: *''Grevillea hakeoides'' Meisn. subsp. ''hakeoides'' has more or less cylindrical leaves usually long and wide, and greenish-white to creamy-grey or pinkish flowers; *''Grevillea hakeoides'' subsp. ''stenophylla''

''Grevillea hakeoides'' is listed as Least Concern on the

IUCN Red List of Threatened Species The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biologi ...

. Both subspecies of ''G. hakeoides'' are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions. The species has a widespread distribution and a stable population, though historically, much of its range within the Wheatbelt region of Western Australia has been reduced. In this area, much of the population is primarily limited to road verges where it is threatened by altered fire regimes, clearance and competition with invasive weed species. These threats are currently not substantial enough to affect the general population.
