Banksia proteoides

Banksia proteoides, commonly known as king dryandra, is a shrub endemic to Western Australia. It was known as Dryandra proteoides until 2007, when all Dryandra species were transferred to Banksia by Austin Mast and Kevin Thiele.

Description

It is a dense, bushy shrub, without a lignotuber, that reaches up to two metres high. Leaves are linear, 20 to 26 centimetres long and 10 to 20 millimetres long, with a pointed tip and serrated margins. Inflorescence are yellow-brown, but concealed within the long red-brown outer bracts, making the flower head resemble that of a Protea.[1]

Taxonomy

Specimens of B. proteoides were first collected in the 1830s by

lectotype for the species.[4] Lindley also proffered no etymology for the specific epithet, but it is accepted that it is a reference to the similarity of the flower heads to those of Protea.[5]

The species has no infraspecific taxa; in 1870 George Bentham demoted Dryandra ferruginea (now Banksia rufa) to a variety of D. proteoides,[6] but this has since been reinstated to specific rank.[7]

There have been two attempts to transfer the species from Dryandra to a new name: in 1891,

nomenclatural synonym of B. proteoides.[8] More recently, in 2007 the genus Dryandra was transferred into Banksia by Austin Mast and Kevin Thiele,[9] resulting in the publication of the current name for this species, Banksia proteoides (Lindl.) A.R.Mast & K.R.Thiele.[10]

Distribution and habitat

It grows in sandy gravelly soils or sandy loam, in

Southwest Botanic Province.[5][11]

Cultivation

Banksia proteoides is not often cultivated. It requires an extremely well drained soil, being particularly susceptible to poor drainage. It prefers full sun and is hardy to both drought and frost once established. Propagation is by seed, but this is by no means easy. It is thought that the seed must be no older than twelve months, and even germination is erratic and slow.[5]
