Taxonomy
The prolific botanist Robert Brown described Grevillea longifolia in 1830 in his Supplementum primum prodromi florae Novae Hollandiae, the specimen having been collected by George Caley somewhere in Port Jackson (Sydney) near the river. Karel Domin relegated it to a subspecies of Grevillea aspleniifolia, but the consensus is for it as a distinct species. Its name is derived from the Latin words longus "long" and folium "leaf", and refers to the long leaves.
