Description
Banksia arctotidis is a prostrate shrub that typically grows to a height of Template:Cvt, width of Template:Cvt and has a short underground stem. The leaves are linear, Template:Cvt long and Template:Cvt wide, pinnately divided to the midrib with between 25 and 45 sharply pointed lobes on each side. The flower spikes are surrounded by hairy thread-like, egg-shaped and oblong bracts and are composed of between 75 and 100 individual flowers. The perianth is Template:Cvt long and yellow cream-coloured or yellowish brown. Flowering occurs between September and October and the fruit is a partly hairy, egg-shaped follicle Template:Cvt long.[1][2]
Taxonomy and naming
This banksia was first formally described in 1830 by Robert Brown who gave it the name Dryandra arctotidis and published the description in Supplementum primum Prodromi florae Novae Hollandiae.[3][4] In 2007, Austin Mast and Kevin Thiele changed the name to Banksia arctotidis.[5] The specific epithet (arctotidis) is a reference to the genus Arctotis.[6]
Distribution and habitat
Banksia arctotidis grows on sandy soil in kwongan south from Kojonup and Ongerup through the Stirling Range National Park to near Albany.
Ecology
An assessment of the potential impact of climate change on this species found that its range is likely to contract by between 50% and 80% by 2080, depending on the severity of the change.[7]
Conservation status
This banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[1]
