Daviesia campephylla is a species of flowering plant in the family Fabaceae and is endemic to a restricted part of Western Australia. It is a low, spreading shrub with ascending branches, phyllodes shaped like looping caterpillars, and yellow flowers with faint red markings.
Daviesia campephylla is a spreading, often domed shrub that typically grows to high and wide with rough-textured branchlets and phyllodes. Its leaves are reduced to irregularly bent phyllodes often resembling looping caterpillars or s-shaped, mostly long and wide. The flowers are arranged in groups of up to five in leaf axils on a peduncle up to long, each flower on a pedicel long with egg-shaped or oblong bracts about long at the base. The sepals are long and joined at the base, the upper lobes joined for most of their length and the lower three triangular and about long. The flowers are mainly yellow with faint red markings, the standard broadly egg-shaped, long and wide. The wings are spatula-shaped and long and the keel long. Flowering occurs in November and the fruit is a thin-walled pod long.[1]
Daviesia campephylla was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected by Ken Newbey near Munglinup in 1980.[2] The specific epithet (campephylla) means "caterpillar-leaved".[3]
This species of pea grows in a restricted area between Cascade, the Oldfield River and Munglinup on roadsides and nearby mallee in the Mallee biogeographic region of south-western Western Australia.
Daviesia campephylla is classified as "not threatened" by the Department of Biodiversity, Conservation and Attractions.
