 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 .
