Swainsona cornuta is a species of flowering plant in the family Fabaceae and is endemic to the west of Western Australia. It is a low-lying, annual or perennial herb with imparipinnate leaves usually with about 7 elliptic leaflets and racemes of 3 to 7 purple flowers.
Swainsona cornuta is a low-lying annual or perennial herb, usually less than 20 cm (7.9 in) high, its stems covered with long, fine hairs uo to 0.75 mm (0.030 in) long. Its leaves are imparipinnate, less than 50 mm (2.0 in) long, sometimes with stipules up to 10 mm (0.39 in) long at the base of the petiole. There are about 7 elliptic leaflets up to about 10 mm (0.39 in) and 5 mm (0.20 in) wide. The flowers are purple, arranged in racemes up to 150 mm (5.9 in) or more long, with 3 to 7, each flower 10–15 mm (0.39–0.59 in) long on a softly-hairy peduncle 1 mm (0.039 in) long. The sepals are joined at the base, forming a tube about 15 mm (0.59 in) long with the sepal lobes much longer than the sepal tube. The standard petal is 10–15 mm (0.39–0.59 in) long and 8–12 mm (0.31–0.47 in) long, the wings 7–8 mm (0.28–0.31 in) long, and the keel 8–9 mm (0.31–0.35 in) long. Flowering has been observed August.[2][3]
