of four united tepals, and one long wiry style. Perianths are cream at the base and grey-brown at the end. Styles are rusty red-brown with a cream tip, and downwardly hooked rather than straight. The style end is initially trapped inside the upper perianth parts, but breaks free at anthesis. Flower spikes are held erect and are typically terminal on a branch; often other branchlets grow up and around a spike from below. The fruiting structure is a stout woody "cone", around five centimetres (2 inches) in diameter, with a hairy appearance caused by the persistence of old withered flower parts. A "cone" may be embedded with up to 60 follicles, although usually there are very few or even none at all. Unusually for Banksia, each follicle contains just one seed. This is shiny black, oval in shape, about 20 millimetres ( in) long, with a brown papery wing. Taxonomy Banksia brownii was first collected near King George Sound in 1829 by William Baxter, who named it in honour of botanist Robert Brown. A formal description was published by Brown in his 1830 Supplementum Primum Prodromi Florae Novae Hollandiae; thus the full botanic name of the species is Banksia brownii Baxter ex R.Br. Under Brown's taxonomic arrangement, B. brownii was placed in subgenus Banksia verae, the "true banksias", because its inflorescence is a typical Banksia flower spike. 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. brownii placed in series Dryandroideae. 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. This arrangement would stand for over a century. In 1891, Otto Kuntze, in his Revisio Generum Plantarum, rejected the generic name Banksia L.f., on the grounds that the name Banksia had previously been published in 1776 as Banksia J.R.Forst & G.Forst, referring to the genus now known as Pimelea. Kuntze proposed Sirmuellera as an alternative, referring to this species as Sirmuellera brownii. This application of the principle of priority was largely ignored by Kuntze's contemporaries, and Banksia L.f. was formally conserved and Sirmuellera rejected in 1940. 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.
