Banksia ser. Cyrtostylis is a taxonomic series within the plant genus Banksia. First published at sectional rank by George Bentham in 1870, it was demoted to a series by Alex George in 1981. The name has had three circumscriptions.
Bentham published B. sect. Cyrtostylis in Flora Australiensis, as part of his taxonomic arrangement of Banksia, defining it as those taxa with
"Leaves flat or undulate, the margins not revolute, toothed pinnatifid or pinnate. Style arched or nearly straight and turned upwards or curved, but not hooked after flowering, the stigmatic end small, not furrowed."
This definition essentially defined Cyrtostylis as a section for those species that did not possess the characters of the other sections; thus it was highly heterogeneous.
George Bentham's placement and circumscription of B. sect. Cyrtostylis may be summarised as follows:
Bentham's circumscription of Cyrtostylis remained current for over 100 years, only being superseded in 1981 by George's revision.
In 1981, George published a taxonomic revision of Banksia in The genus Banksia L.f. (Proteaceae). He demoted Cyrtostylis to series rank, placing it within Banksia subgenus Banksia, section Banksia. It has remained at this rank since then, so its current name is Banksia ser. Cyrtostylis (Benth.) A.S.George.
George defined Cyrtostylis as those members of B. sect. Banksia with slender flowers, a small pollen-presenter, and beaked follicles. Its type species was given as B. media (Southern Plains Banksia).
