Chorizema rhombeum is a prostrate to ascending or twining shrub. Its leaves are egg-shaped with the narrower end towards the base, or rhombic, long and wide, the upper leaves often lance-shaped and longer. The flowers are orange to pink, or red and yellow, arranged on a peduncle each flower on a pedicel long. The sepals are long and hairy, the upper lobes joined above the middle. The standard petal is long and glabrous, the wings long, and the keel is long. Flowering occurs from August to December and the pod is about long.[1]
Chorizema rhombeum was first formally described in 1811 by Robert Brown in William Aiton's Hortus Kewensis.[2] [3] The specific epithet (rhombeum) means "rhombus", referring to the shape of the leaves.[4]
Chorizema rhombeum grows on gentle slopes, river banks and on exposed coastal sites from about Perth to the Stirling Range in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
