Swainsona acuticarinata is a species of flowering plant in the family Fabaceae and is endemic to arid areas of central Australia. It is a prostrate perennial herb with imparipinnate leaves with 5 to 11 leaflets, and racemes of purple flowers.
Swainsona acuticarinata is a prostrate perennial herb, that typically grows to a height of up to 45 cm (18 in) with several densely softly-hairy stems at the base. The leaves are imparipinnate, 10–50 mm (0.39–1.97 in) long with 5 to 11 egg-shaped leaflets, the leaflets 5–15 mm (0.20–0.59 in) long and 3–7 mm (0.12–0.28 in) wide. The flowers are purple, arranged in racemes 10–150 mm (0.39–5.91 in) long of 2 to 10, each flower 7–10 mm (0.28–0.39 in) long on a pedicel about 2 mm (0.079 in) long with lance-shaped bracts 2–3 mm (0.079–0.118 in) long at the base. The sepals are joined at the base, forming a tube about 1.5 mm (0.059 in) long, the lobes 3 or 4 times longer than the sepal tube. The standard petal is 7–11 mm (0.28–0.43 in) long, 8–10 mm (0.31–0.39 in) wide, the wings 4.5–7 mm (0.18–0.28 in) long, and the keel 6–10 mm (0.24–0.39 in) long and 3–4 mm (0.12–0.16 in) deep. Flowering occurs in most months, and the fruit is an oblong pod 10–15 mm (0.39–0.59 in) long and about 4–5 mm (0.16–0.20 in) wide.[2][3]
