Isostylis (one species) The top-level split into Eubanksia and Isostylis was abandoned by George Bentham in 1870. Instead, Bentham divided the genus into five section, retaining B. sect. Isostylis, but dividing the remaining species into four sections. B. subg. Banksia sensu George In 1981, Alex George published a thorough revision of Banksia in his classic monograph The genus Banksia L.f. (Proteaceae). George reinstated Meissner's Eubanksia and Isostylis, giving them subgeneric rank. By this time, however, the rules of botanical nomenclature had been formalised in such a way that Eubanksia was required to take the autonym B. subg. Banksia. George's arrangement was overturned in 1996 by Kevin Thiele and Pauline Ladiges, but in 1999 George published a slightly modified version in his treatment of Banksia for the Flora of Australia series of monographs. George's 1999 arrangement is not universally accepted, and accords poorly with recently published cladistic analyses, yet it remains the most recently published arrangement. In George's taxonomic arrangement of Banksia, B. subg. Banksia is further divided into three sections, primarily on the shape
