In 2005, Mast, Eric Jones and Shawn Havery published the results of their cladistic analyses of DNA sequence data for "Banksia". They inferred a phylogeny greatly different from the accepted taxonomic arrangement, including finding "Banksia" to be paraphyletic with respect to "Dryandra". A new taxonomic arrangement was not published at the time, but early in 2007 Mast and Thiele initiated a rearrangement by transferring "Dryandra" to "Banksia", and publishing "B." subg. "Spathulatae" for the species having spoon-shaped cotyledons; in this way they also redefined the autonym "B." subg. "Banksia". They foreshadowed publishing a full arrangement once DNA sampling of "Dryandra" was complete. In the meantime, if Mast and Thiele's nomenclatural changes are taken as an interim arrangement, then "B. menziesii" is placed in "B." subg. "Banksia".
