Since 1998, Austin Mast has been publishing results of ongoing cladistic analyses of DNA sequence data for the subtribe Banksiinae. His analyses has provided compelling evidence for the paraphyly of "Banksia" with respect to "Dryandra", and suggest an overall phylogeny that is very greatly different from George's arrangement. Mast's results clearly recognise "Isostylis" as a distinct clade, but place it in a fairly recent position, within a clade that also contains "B. elegans" (Elegant Banksia) and "B. attenuata" (Candlestick Banksia). It falls a substantial distance from "Dryandra", suggesting that similarities between those two groups are indeed superficial.
