Banksia Ser. Banksia - According To Thiele and Ladiges

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. Their cladogram included a clade consisting of the members of B. ser. Banksia sensu George, together with the four members of George's B. ser. Crocinae:

On the basis of this clade, Thiele and Ladiges abandoned B. ser. Crocinae, transferring its four taxa into B. ser. Banksia. They then divided the series into two subseries, placing B. ornata (Desert Banksia), B. serrata and B. aemula in B. subser. Banksia, and all other species in B. subser. Cratistylis.

The placement and circumscription of B. ser. Banksia in Thiele and Ladiges' arrangement may be summarised as follows:
