"Banksia" subg. "Spathulatae" is a valid botanic name for a subgenus of "Banksia". It was published in 2007 by Austin Mast and Kevin Thiele, and defined as containing all those "Banksia" species having spathulate (spoon-shaped) cotyledons.cite journal | author = Mast, Austin R. and Kevin R. 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] The name was published to accommodate forthcoming changes to the taxonomic arrangement of "Banksia", based on the DNA sequence analyses of Austin Mast and others, which suggested a phylogeny for "Banksia" very greatly different from the accepted taxonomic arrangement. They found "Banksia" to be paraphyletic with respect to "Dryandra", and that these two genera were best split into two clades, one with beaked follicles and non-spathulate cotyledons, the other with unbeaked follicles and spathulate cotyledons.cite journal | author = Mast, Austin R. | year = 1998 | title = Molecular systematics of subtribe Banksiinae (Banksia and Dryandra; Proteaceae) based on cpDNA and nrDNA sequence data: implications for taxonomy and biogeography | journal = Australian Systematic Botany | volume = 11 | pages = 321–342 | doi = 10.1071/SB97026] cite journal | author = Mast, Austin R. and Thomas J.

"Spathulatae" for the species having spathulate cotyledons. The type species of "Spathulatae" was given as "B. integrifolia" (Coast Banksia), but no further details have been given. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of "Dryandra" is complete.
