Banksia comosa, commonly known as Wongan dryandra, is a species of shrub that is endemic to Western Australia. It has linear leaves with widely spaced, sharply pointed serrations, heads of yellow flowers and glabrous fruit.
Banksia comosa is a dense, bushy shrub that typically grows to a height of but does not form a lignotuber. It has linear, often bent leaves that are long and wide on a petiole up to long. Each side of the leaf has between eight and fifteen well-shaped, sharply pointed, narrow triangular teeth. The flowers are borne in heads of 110 to 150, the heads surrounded by dark reddish brown involucral bracts that are up to long. The flowers have a yellow perianth long and a pistil long. Flowering occurs from August to October and the fruit is a broadly egg-shaped, more or less glabrous follicle long.[1]
This species was first formally described in 1848 by Carl Meissner who gave it the name Dryandra carlinoides and published the description in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond.[2] [3] The specific epithet (comosa) is a Latin word meaning "having tufts of hairs or of leaves".[4] In 2007 Austin Mast and Kevin Thiele transferred all dryandras to the genus Banksia and renamed this species Banksia comosa.[5] [6]
Wongan dryandra grows in kwongan and is only known from Wongan Hills.
This banksia is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife, meaning that is rare or near threatened.[7]
