Subgenus in the family Proteaceae

Banksia subg. Banksia is a valid botanic name for a subgenus 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 verae was renamed Eubanksia by Stephan Endlicher in his 1847 fourth supplement to Genera Plantarum Secundum Ordines Naturales Disposita, and this name was retained in Carl Meissner's 1856 arrangement. Meissner gave Eubanksia sectional rank, further dividing it into four series, B. ser. Abietinæ, B. ser. Salicinae, B. ser. Quercinae and B. ser. Dryandroideae. These series were defined in terms of leaf shape alone, and were hence all highly heterogeneous, with the exception of B. ser. Abietinæ, which contained only (but not all) species with hooked styles.

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 of the style. B. sect. Banksia species have a straight or curved, but never hooked, style; this section contains about 50 species that are further divided into nine series. B. sect. Coccinea contains a single species, Banksia coccinea. B. sect. Oncostylis contains those species whose styles are hooked; it contains about 20 species, which are further divided into four series. It is circumscribed as follows:

In Thiele and Ladiges' taxonomic arrangement of Banksia, B. subg. Banksia is divided into twelve series. Its placement and circumscription may be summarised as follows: A new taxonomic arrangement was not published at the time, but early in 2007 Mast and Thiele initiated a rearrangement by transferring Dryandra to Banksia, and publishing B. subg. Spathulatae for the species having spoon shaped cotyledons. Thus B. subg. Banksia was redefined as containing the species lacking spoon shaped cotyledons. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete.
