Styphelia ciliosa is a species of flowering plant in the heath family Ericaceae and is endemic to a small area of Western Australia. It is usually an erect shrub with narrowly elliptic to narrowly egg-shaped leaves with the narrower end towards the base, and white flowers usually arranged in pairs in leaf axils.
Styphelia ciliosa is usually an erect shrub that typically grows up to high and wide, its young branchlets hairy. The leaves are directed upwards and are narrowly elliptic to narrowly egg-shaped with the narrower end towards the base, long and wide on a petiole long. Both sides of the leaves are more or less glabrous, but the lower surface is a lighter shade of green. The flowers are usually arranged in pairs in leaf axils with egg-shaped bracts long and bracteoles long and long at the base. The sepals are narrowly egg-shaped, long and wide, the petals white, forming a tube long with lobes long and bearded on the inside. Flowering mainly occurs from September to November and the fruit is narrowly elliptic, long and wide.[1]
Styphelia ciliosa was first formally described in 2019 by Michael Clyde Hislop and Caroline Puente-Lelievre in the journal Nuytsia from specimens collected by Hislop in the Moore River National Park in 1999.[2] The specific epithet (ciliosa) means "full of fine hairs", referring to the scales on the nectary of this species.
This styphelia grows in Banksia woodland between the Warradarge area and Badgingarra, and around Keysbrook, in the Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.
Styphelia ciliosa is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
