Since 1998, Austin Mast has been publishing results of ongoing cladistic analyses of DNA sequence data for the subtribe Banksiinae, which comprises "Banksia" and "Dryandra". With respect to "B. brownii", Mast's results are somewhat at odds with those of both George and Thiele and Ladiges, finding it to be more closely related to "B. nutans" (nodding banksia) and "B. quercifolia" (oak-leaved banksia) than to many of the "Spicigerae". Overall, the inferred phylogeny is very greatly different from George's arrangement, and provides compelling evidence for the paraphyly of "Banksia" with respect to "Dryandra". Early in 2007, Mast and Thiele initiated a rearrangement of "Banksia" by transferring "Dryandra" into it, and publishing "B." subg. "Spathulatae" for the species having spoon-shaped cotyledons. 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. brownii" is placed in "B." subg. "Spathulatae".
