 During data collection for The Banksia Atlas project, a single presumed natural hybrid between B. prionotes and B. lindleyana (porcupine banksia), with fruit like B. lindleyana but leaves intermediate between the two parents, was found north of Kalbarri National Park. At the time this was considered an important discovery, as the parent species were thought not to be closely related. Mast's analyses, however, place them both in a clade of eight species, though B. lindleyana remains less closely related to B. prionotes than B. hookeriana. Hybrids of B. prionotes with B. menziesii (firewood banksia) have also been produced by artificial means, and presumed natural hybrids have been recorded.
