"Banksieaeidites" is a plant genus that encompasses fossil pollen that can be attributed to the Proteaceae tribe "Banksieae", but cannot be attributed to a genus.

It was published in 1950 by Isabel Cookson and Suzanna Duigan, on the grounds that the two then-members of "Banksieae", "Banksia" and "Dryandra", cannot be distinguished by the pollen.cite journal | author = Cookson, Isabel C. and Duigan, Suzanne L. | year = 1950 | title = Fossil Banksieae from Yallourn, Victoria, with notes on the morphology and anatomy of living species | journal = Australian Journal of Scientific Research, Series B (Biological Sciences) | volume = 3 | issue = 2 | pages = 133–165]

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",cite journal | author = Vadala, Anthony J. and Drinnan, Andrew N. | year = 1998 | title = Elaborating the Fossil History of Banksiinae: A New Species of Banksieaephyllum (Proteaceae) from the Late Paleocene of New South Wales | journal = Australian Systematic Botany | volume = 11 | pages = 439–463 | url = http://www.publish.csiro.au/?act=view_file&file_id=SB97021.pdf | accessdate = 2006-11-15 | doi = 10.1071/SB97021] while others now treat it as defined in terms of "Banksiinae".cite journal | author = Carpenter, Raymond J. and Gregory J. Jordan | year = 1997 | title = Early tertiary macrofossils of Proteaceae from Tasmania | journal = Australian Systematic Botany | volume = 10 | pages = 533–563 | doi = 10.1071/SB96016] "Dryandra" has now been transferred into "Banksia".cite journal | author = Mast, Austin R. and Kevin Thiele | year = 2007 | title = The transfer of Dryandra R.Br. to Banksia L.f. (Proteaceae) | journal = Australian Systematic Botany | volume = 20 | pages = 63–71 | doi = 10.1071/SB06016] Although as yet undetermined, the latter interpretation would result in "Banksieaeidites" becoming a nomenclatural synonym of "Banksia".Or|date=September 2007

ee also

* "Banksieaephyllum", a genus for specimens of organically preserved fossil leaves that can be attributed to subtribe "Banksiinae", but not to a genus.
* "Banksieaeformis", a genus for fossil leaves with the same architecture as "Banksieaephyllum", but without organic detail; like "Banksieaephyllum", these can be attributed to subtribe "Banksiinae", but not to a genus.
