'', cannot be distinguished by the pollen. Since then, ''Banksia'' and ''Dryandra'' have been further grouped into subtribe Banksiinae, and another subtribe, Musgraveinae, erected to contain two new genera. The correct interpretation for ''Banksieaeidites'' does not appear to have been clarified since then, but treatment of the analogous genus for fossil leaves, '' Banksieaephyllum'', is no longer consistent, with some botanists holding that it is still defined in terms of Banksieae, while others now treat it as defined in terms of Banksiinae. ''Dryandra'' has now been transferred into ''Banksia''. Although as yet undetermined, the latter interpretation would result in ''Banksieaeidites'' becoming a nomenclatural synonym of ''Banksia''. Species include: * '' Banksieaeidites arcuatus'' * '' Banksieaeidites elongatus'' * '' Banksieaeidites minimus''
