Taxonomy

Grevillea armigera was first formally described in 1856 by Swiss botanist Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond in the Swan River Colony.[3][4] The specific epithet (armigera) means "furnished with thorns".[5]

Distribution and habitat

Prickly toothbrushes grows in heath and shrubland from Buntine to near Dowerin in the Avon Wheatbelt and Geraldton Sandplains biogeographic regions.[1][2]

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.[6]
