Taxonomy
This species was first formally described in 1794 by James Edward Smith who gave it the name Embothrium boxifolium in his A Specimen of the Botany of New Holland.{{cite web|title=Embothrium buxifolium|url= https://id.biodiversity.org.au/instance/apni/543621 |publisher=APNI|access-date=2 February 2022}}{{cite book |last1=Smith |first1=James Edward |title=A Specimen of the Botany of New Holland |date=1794 |pages=29–30 |url=https://bibdigital.rjb.csic.es/viewer/13806/?offset=#page=47&viewer=picture&o=bookmark&n=0&q= |access-date=2 February 2022}} In 1810, Robert Brown changed the name to Grevillea buxifolia in Transactions of the Linnean Society of London.{{cite web|title=Grevillea buxifolia|url= https://id.biodiversity.org.au/instance/apni/540089 |publisher=APNI|access-date=2 February 2022}} The specific epithet (buxifolia) means "box-tree-leaved".{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=153 |edition=3rd}}

Distribution and habitat
Grey spider flower grows in woodland or heath in New South Wales, on the South Coast, Central Coast and inland to near Pigeon House Mountain west of Ulladulla.{{cite web |last1=Wood |first1=Betty |title=Grevillea buxifolia subsp. buxifolia |url=https://apps.lucidcentral.org/plants_se_nsw/text/entities/grevillea_buxifolia_subsp._buxifolia.htm |publisher=Lucid Keys |access-date=2 February 2022}} Subspecies ecorniculata is restricted to the area between Putty, Gospers Mountain and Wollombi north-west of Sydney.
Conservation status
Despite its relatively limited distribution, Grevillea buxifolia is listed as Least Concern on the IUCN Red List of Threatened Species, as it is locally common, its population is presumed to be stable, it occurs within protected areas and there are no major threats currently affecting it. The main threat to this species is inappropriate fire regimes, meaning an increased frequency in bushfires.{{cite iucn |author=Ford, A. |year=2020 |title=Grevillea buxifolia |volume=2020 |page=e.T112648471A113309250 |doi=10.2305/IUCN.UK.2020-2.RLTS.T112648471A113309250.en |access-date=21 December 2023}}
