Taxonomy
Grevillea spinosa was first formally described by the botanist Donald McGillivray in 1986 as a part of the work New Names in Grevillea (Proteaceae) from specimens collected on the Canning Stock Route in 1942.[4]
The specific epithet (spinosa) is means "spiny", referring to the leaves.[1][5]
