suggested that the closest relatives of ''B. laricina'' appeared to be '' B. incana'' and '' B. tricuspis''. In their taxonomic arrangement, Thiele and Ladiges placed ''B. laricina'' in series ''Abietinae'', subseries ''Longistyles''. Thiele and Ladiges' arrangement was not accepted by George, and was largely discarded by him in his 1999 arrangement in '' Flora of Australia''.

Distribution and habitat

Rose banksia is restricted to a small area near the Moore River and Regans Ford where it grows in low woodland.
