Banksia rufa" subsp. "magna is a subspecies of "Banksia rufa". It was known as Dryandra ferruginea" subsp. "magna until 2007, when Austin Mast and Kevin Thiele sunk all "Dryandra" into "Banksia". Since the name "Banksia ferruginea" had already been used, Mast and Thiele had to choose a new specific epithet for "D. ferruginea" and hence for this subspecies of it. As with other members of "Banksia" ser. "Dryandra", it is endemic to the South West Botanical Province of Western Australia.
