Banksia seneciifolia is a species of column-shaped shrub that is endemic to the south-west of Western Australia. It has linear, pinnatifid leaves, yellow flowers in heads of about twenty-five, and narrow egg-shaped follicles.

Description

Banksia seneciifolia is a column-shaped shrub that grows to a height of 0.6–1.0 m (2 ft 0 in – 3 ft 3 in) but does not form a lignotuber. It has linear, pinnatifid leaves 30–50 mm (1.2–2.0 in) long and 5–15 mm (0.20–0.59 in) wide on a petiole up to 15 mm (0.59 in) long. There are between two and five linear lobes up to 9 mm (0.35 in) long on each side of the leaves. About twenty-five yellow flowers are arranged in heads surrounded by linear, tapering, hairy involucral bracts up to 17 mm (0.67 in) long at the base of each head. The perianth is 12–14 mm (0.47–0.55 in) long and curved downwards, and the pistil is 17–19 mm (0.67–0.75 in) long and also curved downwards. Flowering occurs from July to August. A single, narrow egg-shaped follicle 7–9 mm (0.28–0.35 in) long forms in each head. [2] [3]

Taxonomy and naming

This species was first formally described in 1830 by Robert Brown who gave it the name Dryandra seneciifolia and published the description in the Supplementum primum Prodromi florae Novae Hollandiae from specimens collected by William Baxter near King George's Sound in 1829. [4] [5] The specific epithet (seneciifolia) refers to the genus Senecio with the ending -folia from the Latin -folius meaning "-leaved". [6]

In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia seneciifolia. [7] [8]

Distribution and habitat

Banksia seneciifolia grows in mallee-kwongan in the Stirling Range National Park but there are record from before 1900 as far south as Albany. [3]

Conservation status

This banksia is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife, [2] meaning that is rare or near threatened. [9]

Dryandra subg. Diplophragma is an obsolete subgenus within the former genus Dryandra. It was first published by Robert Brown in 1830, but was discarded by George Bentham in 1870. It was reinstated with a new circumscription by Alex George in 1996, but was ultimately discarded again in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.

Robert Brown'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 and Alex George.

<i>Dryandra</i> subg. <i>Hemiclidia</i> Obsolete subgenus within the former genus Dryandra

Dryandra subg. Hemiclidia is an obsolete plant taxon that encompassed material that is now included in Banksia. Published at genus rank as Hemiclidia by Robert Brown in 1830, it was set aside by George Bentham in 1870, but reinstated at subgenus rank by Alex George in 1996. In 2007, all Dryandra species were transferred into Banksia at series rank, and the infrageneric Dryandra taxa, including D. subg. Hemiclidia, were set aside.
