Grevillea leucopteris, also known as Old Socks or White Plume Grevillea, is a shrub which is endemic to the south-west of Western Australia. It grows up to 5 metres in height and produces white or cream unpleasantly-scented flowers between July and January (mid winter to mid summer) in its native range. The species was first formally described by botanist Carl Meissner, his description published in Hooker's Journal of Botany and Kew Garden Miscellany in 1855.
