ⓘ Banksia subulata

It was first published as Dryandra subulata by Charles Gardner in 1964. In Alex Georges 1996 arrangement, this species was recognised as quite distinctive, being unusual in its long, unserrated leaves, its rigid awl-shaped floral leaves, and its round follicles. With no obvious relatives, the species was placed alone in a new series named Dryandra ser. Subulatae.

Since 1998, Austin mast publishes the results of cladistics analyses of data of DNA sequences for potrebu Banksiinae. His analysis provided compelling evidence of the paraphyly of Banksia with respect to Dryandra to, that is, it seems that Dryandra arose in the ranks of "Banksia". Early in 2007, mast and Kevin Thiele initiated a redistribution of Banksia sinking Dryandra into it, thus Dryandra subulata became Banksia subulata. Analyses of the B. subulata mast is placed not with other selected species of Dryandra, and a small hoard of Banksia species themselves reduced the axis of the inflorescence. For this reason, B. subulata were placed incertae Sedis in B. subg; it. Banksia, but not in B. ser. Dryandra with other species of Dryandra.

The transfer of Dryandra to Banksia demanded the abolition of Georges intrapartum organization Dryandra, D. ser. Subulatae does not exist. Mast and Thiele have already foreshadowed publishing a full arrangement once sampling DNA Dryandra is complete.
