According to Meissner B. ser.
Salicinae was first published in 1856, in
Carl Meissner's chapter on the
Proteaceae in
A. P. de Candolle's
Prodromus systematis naturalis regni vegetabilis. It was one of four series into which the subgenus
Eubanksia was divided. These four series were defined in terms of leaf characters, with series
Salicinae containing the species with linear, or nearly so, leaves with hoary grey undersides. As they were defined on leaf characters alone, all of Meissner's series were highly heterogeneous. The placement and circumscription of
B. ser.
Salicinae in
Meissner's arrangement may be summarised as follows:
According to George In 1981,
Alex George published a thorough revision of
Banksia in his classic monograph
The genus Banksia L.f. (Proteaceae). He reinstated
B. ser.
Salicinae, placing it within
B. sect. Banksia, and defining it as containing only those species with entire, serrate or dentate leaves; a small
pollen-presenter; and unbeaked
follicles. :

B. ser.
Banksiae, but this is probably a typographical error, as the name has not been validly published. In 1991, the
Tasmanian fossil taxon
B. kingii was placed in this series.
According to Thiele and Ladiges In 1996,
Kevin Thiele and Pauline Ladiges undertook a
cladistic analysis of
morphological characters of
Banksia, which yielded a
phylogeny somewhat at odds with George's taxonomic arrangement. They found George's
B. ser.
Salicinae to be
monophyletic, their
cladogram placing it in a
clade whose sister clade consisted of the members of George's
B. ser. Quercinae and
B. ser. Spicigerae: |1= |2= }} }} Thiele and Ladiges therefore retained George's
B. ser.
Salicinae, further dividing it into two subseries,
B. subser. Acclives and
B. subser. Integrifoliae, in accordance with the resolution of
clades in their analysis. The placement and circumscription of
B. ser.
Abietinae in
Thiele and Ladiges' arrangement may be summarised as follows: :

Banksia ser. Abietinae (4 subseries, 15 species, 8 varieties) Thiele and Ladiges' arrangement remained current only until 1999, when George's treatment of the genus for the
Flora of Australia series of monographs was published. This was essentially a revision of George's 1981 arrangement, which took into account some of Thiele and Ladiges' data, but rejected their overall arrangement. With respect to
B. ser.
Abietinae, George's 1999 arrangement was fundamentally the same as his 1981, but differed in the ranking of some taxa, the inclusion of some newly published taxa, and changes to the
phyletic order. |1=

B. paludosa }} }} Early in 2007 Mast and Thiele initiated a rearrangement of
Banksia by transferring
Dryandra into it, and publishing
B. subg. Spathulatae for the species having spoon-shaped
cotyledons; in this way they also redefined the
autonym B. subg. Banksia as containing those taxa lacking spoon-shaped cotyledons. The members of
B. ser.
Quercinae fall within
B. subg.
Spathulatae, but no further details have been proffered. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of
Dryandra is complete. ==Distribution==
