's taxonomic arrangement of Dryandra was the first arrangement of what is now Banksia ser. Dryandra. His initial arrangement was published in 1810, and a further arrangement, including an infrageneric classification, followed in 1830. Aspects of Brown's arrangements can be recognised in the later arrangements of George Bentham

Background

The dryandras are a group of proteaceous
Proteaceae
Proteaceae is a family of flowering plants distributed in the Southern Hemisphere. The family comprises about 80 genera with about 1600 species. Together with the Platanaceae and Nelumbonaceae they make up the order Proteales. Well known genera include Protea, Banksia, Embothrium, Grevillea,...

It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Indian Ocean to the south, the Northern Territory to the north-east and South Australia to the south-east...

 as B. ser. Dryandra. There are now nearly 100 species, plus numerous subspecies and varieties.

Brown's 1810 arrangement

The genus Dryandra was first published by Brown in "On the natural order of plants called Proteaceae", which was read to the Linnean Society of London

 in 1809, and published the following year in Volume X of Transactions of the Linnean Society of London. Brown listed 13 species, but did not attempt an infrageneric classification of them. Later that year, he republished his descriptions of Dryandra in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen
Prodromus Florae Novae Hollandiae et Insulae Van Diemen

Brown's 1830 arrangement

. He added a further 11 species to Dryandra, but transferred D. falcata into a new, monospecific genus as Hemiclidia Baxteri, on the grounds that its follicles always contained only a single seed. The remaining 23 Dryandra species were divided into three sections based on the number of seed separators in each follicle
Follicle (fruit)
In botany, a follicle is a dry unilocular many-seeded fruit formed from one carpel and dehiscing by the ventral suture in order to release seeds, such as in larkspur, magnolia, banksia, peony and milkweed....

. He allowed for these groups to be given subgenus rather than sectional rank, but they are now treated as having been published as sections.

The first section was defined as containing those species with a single seed separator. This accounted for the majority of species, and was named Dryandra verae ("True Dryandra"). D. sect. Diplophragma, was a monotypic section containing D. bipinnatifida (now B. bipinnatifida
Banksia bipinnatifida

As Mast and Thiele were not yet ready to propose an infrageneric classification for their new circumscription of Banksia, they transferred Dryandra into Banksia at series rank, so as to cause minimal disruption to the current arrangement of Banksia.
