Swainsona luteola, commonly known as dwarf Darling pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to the eastern Australia. It is a prostrate or low-lying to semi-erect perennial with imparipinnate leaves with usually 3 to 17 narrowly elliptic leaflets, and racemes of 5 to 15 purple, sometimes yellow flowers.
Swainsona luteola is a prostrate or low-lying to semi-erect perennial plant, that typically grows to a height of up to about 50 cm (20 in) and has hairy stems. The leaves are imparipinnate, mostly 30–100 mm (1.2–3.9 in) long with 3 to 17 narrowly elliptic leaflets, the side leaflets 5–20 mm (0.20–0.79 in) long and 3–10 mm (0.12–0.39 in) wide with stipules 2–5 mm (0.079–0.197 in) long at the base of the petioles. The flowers are purple, sometimes yellow, 6–8 mm (0.24–0.31 in) long, arranged in racemes of 5 to 15, 10–80 mm (0.39–3.15 in) long, on a peduncle 0.5–1.5 mm (0.020–0.059 in) long. The sepals are joined at the base to form a tube 1.5–2.0 mm (0.059–0.079 in) long, with lobes equal to or longer than the tube. The standard petal is 6–9 mm (0.24–0.35 in) long and 5–8 mm (0.20–0.31 in) wide, the wings 3–5 mm (0.12–0.20 in) long and the keel 5–8.5 mm (0.20–0.33 in) long and about 2 mm (0.079 in) deep. The fruit is a narrowly elliptic pod 20–35 mm (0.79–1.38 in) long and 3–8 mm (0.12–0.31 in) wide, with the remains of the curved style 1.0–1.25 mm (0.039–0.049 in) long.[2][3]
