About Chorizema rhombeum R.Br.
Chorizema rhombeum R.Br. is a prostrate, ascending, or twining shrub. Its leaves are either egg-shaped with the narrow end at the base, or rhombic, measuring 7–25 mm long and 6–8 mm wide; upper leaves are often lance-shaped and longer than lower leaves. Flowers of this species range in color from orange to pink, or red and yellow. They are arranged on a peduncle, with each individual flower borne on a pedicel 3.0–3.4 mm long. The sepals are 9–10 mm long and covered in hairs, with the upper lobes joined together above the middle. The standard petal is 4–10 mm long and glabrous, the wing petals are 11–12 mm long, and the keel petal is 9–11 mm long. Flowering takes place from August to December, and the resulting seed pod is approximately 6 mm long. This species grows on gentle slopes, river banks, and exposed coastal sites. Its distribution extends from around Perth to the Stirling Range, within the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
