Swainsona vestita is a species of flowering plant in the family Fabaceae and is endemic to central-northern South Australia. It is an erect or ascending perennial plant with imparipinnate leaves with about 7 narrowly lance-shaped leaflets, and racemes of 5 to 20 purple flowers.
Swainsona vestita is an erect or ascending perennial plant that typically grows to a height of up to about 25 cm (9.8 in), and has many strongly ridged stems. Its leaves are imparipinnate, about 30–100 mm (1.2–3.9 in) long with about 7 narrowly lance-shaped leaflets, the side leaflets mostly 10–25 mm (0.39–0.98 in) long, 1–3 mm (0.039–0.118 in) wide and hairy. There is a stipule mostly about 5 mm (0.20 in) long at the base of the petiole. The flowers are arranged in racemes 50–200 mm (2.0–7.9 in) long with 5 to 20 flowers on a peduncle 1.0–1.5 mm (0.039–0.059 in) wide, each flower about 10 mm (0.39 in) long on a hairy pedicel about 1–3 mm (0.039–0.118 in) long. The sepals are joined at the base, forming a tube 2.0–2.5 mm (0.079–0.098 in) long, the sepal lobes about as slightly longer than the tube. The petals are purple, the standard petal 10–12 mm (0.39–0.47 in) long and 9–12 mm (0.35–0.47 in) wide, the wings 8–10 mm (0.31–0.39 in) long, and the keel about 10–11 mm (0.39–0.43 in) long and about 4 mm (0.16 in) deep.[2]
