The next change to "Isostylis" came in 1981, when Alex George promoted it back to subgenus rank, and published a second species, "B. cuneata". In discussing the subgenus, George commented that there had been calls to transfer "Isostylis" into "Dryandra", which was then a distinct genus. He argued, however, that the similarities between "Isostylis" and "Dryandra" were largely superficial, whereas the similarities with "Banksia" were much more important taxonomically. His conclusion was that the taxon should remain in "Banksia", although he did not rule out promoting it into a separate genus. A third "B." subg. "Isostylis" species, "B. oligantha", was published by George in 1988.
