Banksia ser. Banksia is a valid botanic name for a series of Banksia. As an autonym, it necessarily contains the type species of Banksia, B. serrata (Saw Banksia). Within this constraint, however, there have been various circumscriptions.
Banksia ser. Banksia originated in 1870 as Banksia sect. Orthostylis. Published by George Bentham in 1870, B. sect. Orthostylis consisted of those Banksia species with flat leaves with serrated margins, and rigid, erect styles that "give the cones after the flowers have opened a different aspect". The placement and circumscription of B. sect. Orthostylis in Bentham's arrangement can be summarised as follows:
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.
