Banksia platycarpa is a species of small shrub that is endemic to the south-west of Western Australia. It has broadly linear pinnatipartite leaves, with up to twenty-five sharply pointed lobes on each side, creamy-yellow to orange flowers in heads of up to seventy-five, and egg-shaped follicles.
Banksia platycarpa is a shrub with column-like branches that typically grows to a height of, has hairy stems and does not form a lignotuber. Its leaves are broadly linear and pinnatipartite, long and wide with between ten and twenty-five sharply-pointed, linear to narrow triangular lobes up to long on each side. The flowers are creamy-yellow to orange and arranged in heads of between sixty and seventy-five with many linear involucral bracts about long at the base of the head. The perianth is long and the pistil long and downturned. Flowering occurs from May to August and the follicles are egg-shaped, long and wide.[1] [2]
This species was first formally described in 1996 by Alex George who gave it the name Dryandra platycarpa and published the description in the journal Nuytsia from specimens he collected in the Alexander Morrison National Park in 1986.[3] The specific epithet (platycarpa) is from Greek words meaning "wide" and "fruit", referring to the follicles.
In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia platycarpa.[4] [5]
Banksia platycarpa grows in kwongan between Eneabba and Mogumber.
This Banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
