Jabarkan Berdasarkan Thiele dan Ladiges dari Banksia ser. Salicinae

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:

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:BanksiaB. subg. Isostylis (3 species)B. elegans (incertae sedis)
