Banksia fililoba is a species of shrub that is endemic to Western Australia. It has pinnatipartite leaves with sharply pointed lobes, heads of up to eighty yellowish flowers and egg-shaped fruit. It mainly grows in kwongan in the south-west of the state.
Banksia fililoba is a tangled shrub that typically grows to a height of but does not form a lignotuber. It has hairy stems and deeply pinnatipartite leaves that are long and wide on a petiole long. There are between ten and seventeen sharply-pointed, linear leaves long on each side of the leaves. The flowers are borne on a head containing between fifty-five and eighty flowers in each head. There are egg-shaped to oblong involucral bracts long, densely covered with silky, rusty brown hairs at the base of the head. The flowers have a pale yellow perianth long and a cream-coloured pistil long. Flowering mainly occurs from May to July and the follicles are egg-shaped, about long and hairy at first.[1] [2]
This banksia was first formally described in 1996 by Alex George in the journal Nuytsia from specimens he collected near Lake Grace, and given the name Dryandra fililoba.[3] In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia fililoba.[4] [5] The specific epithet (fililoba) is from Latin words meaning "a thread" and "a lobe" referring to the fine lobes of the leaves.
Banksia fililoba grows in kwongan, sometimes in wandoo woodland, between Woodanilling, Lake Grace and Harrismith in the Avon Wheatbelt and Mallee biogeographic regions.
This banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
