Swainsona dictyocarpa is a species of flowering plant in the family Fabaceae and is endemic to central areas of South Australia. It is a small erect perennial herb with imparipinnate leaves with 3 to 7 elliptic leaflets, and racemes of purple flowers in racemes of 2 to 6.
Swainsona dictyocarpa is an erect perennial herb, that typically grows to a height of up to 6 cm (2.4 in) and has gabrous stems. The leaves are imparipinnate, mostly 8–10 mm (0.31–0.39 in) long with 3 to 7 elliptic leaflets, the leaflets 5–9 mm (0.20–0.35 in) long and 2–4 mm (0.079–0.157 in) wide on a petiole 10–15 mm (0.39–0.59 in) long. There are lance-shaped stipules 1–2 mm (0.039–0.079 in) long at the base of the petioles. The flowers are purple, arranged in racemes of 2 to 6 on a peduncle 25–100 mm (0.98–3.94 in) long with bracts 1–2 mm (0.039–0.079 in) long at the base. Each flower is 8–10 mm (0.31–0.39 in) long on a pedicel about 2 mm (0.079 in) long, the sepals 5–6 mm (0.20–0.24 in) long and joined at the base with lance-shape lobes longer than the tube. The standard petal is about 10 mm (0.39 in) long, the wings about 8 mm (0.31 in) long and the keel 8 mm (0.31 in) long. Flowering usually occurs from June to October, and the fruit is a cylindrical pod 12–14 mm (0.47–0.55 in) long and 3–5 mm (0.12–0.20 in) wide.[2][3]
