More recently, however, Alf Salkin has argued that White probably collected the type material of B. spinulosa in 1792. The following year, the species was formally described by Smith in his A Specimen of the Botany of New Holland. It was thus the seventh Banksia species collected, and the fifth described. Smith gave it the specific epithet spinulosa, a Latin term meaning having minute spines, probably in reference to the leaf tips. Thus the species' full name is Banksia spinulosa Sm. Placement within Banksia In the first infrageneric arrangement of Banksia, that of Brown in 1830, B. spinulosa was placed in subgenus Banksia verae, the "true banksias", because its inflorescence is a typical Banksia flower spike. It was placed next to B. cunninghamii and B. collina, both now considered varieties of B. spinulosa; these three were placed between B. ericifolia (heath-leaved banksia) and B. occidentalis (red swamp banksia). Banksia verae was renamed Eubanksia by Stephan Endlicher in 1847. Carl Meissner demoted Eubanksia to sectional rank in his 1856 classification, and divided it into four series, with B. spinulosa placed in series Abietinae, while B. cunninghamii and B. collina were placed alongside each other in series Salicinae. When George Bentham published his 1870 arrangement in Flora Australiensis, he discarded Meissner's series, placing all the species with hooked styles together in a section that he named Oncostylis. B. cunninghamii was reduced to synonymy with B. collina, as was the western species B. littoralis (western swamp banksia). This arrangement would stand for over a century. Alex George published a new taxonomic arrangement of Banksia in his landmark 1981 monograph The genus Banksia L.f. (Proteaceae). Endlicher's Eubanksia became B. subg. Banksia, and was divided into three sections, one of which was Oncostylis. Oncostylis was further divided into four series, with B. spinulosa placed in series Spicigerae because its inflorescences are cylindrical. In 1996, Kevin Thiele and Pauline Ladiges published a new arrangement for the genus, after cladistic analyses yielded a cladogram significantly different from George's arrangement. Thiele and Ladiges' arrangement retained B. spinulosa in series Spicigerae, placing it alone in B. subser. Spinulosae. This arrangement stood until 1999, when George effectively reverted to his 1981 arrangement in his monograph for the Flora of Australia series. Under George's taxonomic arrangement of Banksia, B. spinulosas taxonomic placement may be summarised as follows: Genus Banksia Subgenus Banksia Section Banksia Section Coccinea Section Oncostylis Series Spicigerae B. spinulosa
