Distribution and habitat

Prickly toothbrushes grows in heath and shrubland from Buntine to near Dowerin in the Avon Wheatbelt and Geraldton Sandplains biogeographic regions.

Conservation status

Grevillea armigera is listed as "Near Threatened" on the IUCN Red List of Threatened Species. Although it is fairly common within its range, its distribution is severely fragmented due to historical clearance for agriculture. It is currently threatened by land clearing for roads.
