Swainsona affinis, commonly known as common poison pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to arid areas of inland Australia. It is a prostrate perennial herb with imparipinnate leaves with 7 to 25 broadly elliptic leaflets, and racemes of purple, pink, yellow or white flowers.
Swainsona affinis is a prostrate perennial herb, that typically grows to a height of up to 25 cm (9.8 in) and has softly-hairy stems. The leaves are imparipinnate, 30–50 mm (1.2–2.0 in) long with 7 to 25 broadly elliptic leaflets, the leaflets 5–15 mm (0.20–0.59 in) long and 3–8 mm (0.12–0.31 in) wide. The flowers are arranged in racemes 10–150 mm (0.39–5.91 in) long of 5 to 35 or more on a peduncle 70–300 mm (2.8–11.8 in) long, each flower 8–10 mm (0.31–0.39 in) long. The sepals are joined at the base, forming a tube with lobes shorter than the sepal tube. The petals are purple, pink, yellow or white. Flowering occurs from June to August, and the fruit is a broadly oblong, oval or spherical pod 5–11 mm (0.20–0.43 in) long with the remains of the style 2.5–4.5 mm (0.098–0.177 in) wide.[2][3][4]
