Banksia pilostylis is a species of shrub that is endemic to the south-west of Western Australia. It has hard, fissured bark, narrow wedge-shaped, serrated leaves, pale yellow flowers in cylindrical spikes and elliptical follicles that open when heated in a bushfire.

Description

Banksia pilostylis is a shrub that typically grows to a height of Шаблон:Cvt and has hard, fissured bark but does not form a lignotuber. The leaves are serrated, narrow wedge-shaped, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flowers are pale yellow and closely packed in a cylindrical spike Шаблон:Cvt long and Шаблон:Cvt wide with hairy involucral bracts Шаблон:Cvt long at the base of the spike. The perianth is Шаблон:Cvt long and the pistil Шаблон:Cvt long and curved. Flowering occurs from October to January and up to twenty-five elliptical follicles Шаблон:Cvt long and Шаблон:Cvt wide, surrounded by the remains of the flowers, develop in each spike. The follicles usually remain closed until the plant is killed in a bushfire.[1][2][3][4]

Taxonomy and naming

Шаблон:See also Шаблон:See also Banksia pilostylis was first formally described in 1964 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens he collected in October 1960.[3][5][6] The specific epithet (pilostylis) is from Latin and refers to the hairy style.[7]

In 1981, George placed this species in the series Cyrtostylis. Cladistic analysis in a 1996 paper by Kevin Thiele and Pauline Ladiges confirmed that placement.[8]
