In 1981, Alex George published a thorough revision of "Banksia" in his classic monograph "The genus Banksia L.f. (Proteaceae)". He retained the name "Orthostylis", but demoted it to series rank, placing it in "B." subg. "Banksia" because of its elongate "flower spike", and in "B." sect. "Banksia", because it has straight styles after anthesis. The series was given a rather stricter circumscription to that of Bentham: it was defined as containing only those species with a hairy pistil that is prominently curved before anthesis. The result was a series of just eight species, all of which had been included in Bentham's "B." sect. "Orthostylis". The other eleven members of Bentham's "Orthostylis" were moved into other sections and series.
