It was published in 1950 by Isabel Cookson and Suzanna Duigan, on the grounds that the two then-members of Banksieae, Banksia
Banksia
Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. When it comes to size, banksias range from prostrate woody shrubs to trees up...

and Dryandra
Dryandra
Banksia ser. Dryandra is a series of 94 species of shrub to small tree in the plant genus Banksia. It was considered a separate genus named Dryandra until early 2007, when it was merged into Banksia on the basis of extensive molecular and morphological evidence that Banksia was paraphyletic with...

, 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
