Banksia serra
Banksia serra, commonly known as serrate-leaved dryandra, is a species of shrub that is endemic to Western Australia. It has broadly linear, serrated leaves, pale yellow flowers in heads of about thirty and egg-shaped follicles.
Description
Banksia serra is a shrub that typically grows to a height of but does not form a lignotuber. It has slender stems and broadly linear leaves long and wide on a petiole long. There are between eight and twenty broadly triangular serrations on each side of the leaves. Between twenty and thirty-six pale yellow flowers are arranged in heads with narrow egg-shaped to lance-shaped involucral bracts long at the base of each head. The perianth is long and more or less straight, and the pistil is long with a green pollen presenter. Flowering occurs from July to October and the follicles are egg-shaped but curved, long.Taxonomy and naming
This species was first formally described in 1830 by Robert Brown who gave it the name Dryandra serra and published the description in the Supplementum primum Prodromi florae Novae Hollandiae from specimens collected by William Baxter near King George's Sound in 1829. The specific epithet is a Latin word meaning "saw", referring to the leaves.In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia serra.
