Banksia subg. Spathulatae is a valid botanic name for a subgenus of Banksia . It was published in 2007 by Austin Mast and Kevin Thiele, and defined as containing all those Banksia species having spathulate (spoon-shaped) cotyledons. [1] The name was published to accommodate forthcoming changes to the taxonomic arrangement of Banksia, based on the DNA sequence analyses of Austin Mast and others, which suggested a phylogeny for Banksia very greatly different from the accepted taxonomic arrangement. They found Banksia to be paraphyletic with respect to Dryandra, and that these two genera were best split into two clades, one with beaked follicles and non-spathulate cotyledons, the other with unbeaked follicles and spathulate cotyledons. Initially this clade was informally named "/Cryptostomata", in reference to the stomates, which are sunken with constricted entrances. [2] [3] [4] Accordingly, in 2007 Mast and Thiele initiated a rearrangement by transferring Dryandra to Banksia, and publishing B. subg. Spathulatae for the species having spathulate cotyledons. The type species of Spathulatae was given as B. integrifolia (coast banksia), but no further details have been given. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete. [1]

Banksia subg. Isostylis is a subgenus of Banksia. It contains three closely related species, all of which occur only in Southwest Western Australia. Members of subgenus Isostylis have dome-shaped flower heads that are superficially similar to those of B. ser. Dryandra, but structurally more like reduced versions of the "flower spikes" characteristic of most other Banksia taxa.

<i>Banksia burdettii</i> Species of shrub in the family Proteaceae native to Western Australia

Banksia burdettii, commonly known as Burdett's banksia, is a species of shrub or tree of the genus Banksia in the family Proteaceae. It occurs on sandplain country north of Gingin, Western Australia. Growing to 4 m (13 ft) in height, it has long serrated leaves and large, bright flower spikes, initially white before opening to a bright orange, that appear mainly in late summer. Edmund Gilbert Baker described B. burdettii in 1934, naming it after its collector, W. Burdett.

<i>Banksia nutans</i> Species of shrub in the family Proteaceae native to the south coast of Western Australia

Banksia nutans, commonly known as nodding banksia, is a species of shrub native to the south coast of Western Australia in the genus Banksia. Growing to a metre (3 ft) tall, it has pale blue-green fine-leaved foliage and unusual purple-brown inflorescences which hang upside down rather than grow upright like most other banksias.

<i>Banksia plagiocarpa</i> Species of shrub in the family Proteaceae native to Queensland

Banksia plagiocarpa, commonly known as the Dallachy's banksia or blue banksia, is a species of shrub or tree in the plant genus Banksia. It occurs only on Hinchinbrook Island, Queensland and the immediately adjacent mainland. First collected in 1867, Banksia plagiocarpa was not described until 1981, when Alex George named it in his monograph of the genus Banksia. Genetic studies show it to be related to Banksia aquilonia, Banksia oblongifolia and Banksia robur.

<i>Banksia praemorsa</i> Species of shrub in the family Proteaceae native to Western Australia

Banksia praemorsa, commonly known as the cut-leaf banksia, is a species of shrub or tree in the plant genus Banksia. It occurs in a few isolated populations on the south coast of Western Australia between Albany and Cape Riche.

Banksia saxicola, the rock banksia or Grampians banksia, is a species of tree or shrub in the plant genus Banksia. It occurs in Victoria in two distinct populations, one in The Grampians and the other on Wilsons Promontory. Formerly considered to be a form of B. integrifolia, it was described as a distinct species by Alex George in 1981. It is most closely related to Banksia marginata.
