Swainsona campylantha

Swainsona campylantha is a low-growing perennial herb, that typically grows to a height of up to 25 cm (9.8 in) with more or less glabrous, strongly ribbed stems. Its leaves are imparipinnate, mostly 30–60 mm (1.2–2.4 in) long on short petiole with up to 7 narrowly lance-shaped to narrowly elliptic leaflets 5–60 mm (0.20–2.36 in) long and 1–5 mm (0.039–0.197 in) wide. There are stipules 1–15 mm (0.039–0.591 in) long at the base of the petiole. The flowers are arranged in racemes 50–100 mm (2.0–3.9 in) long of 2 to 10 on a peduncle 1.5–3 mm (0.059–0.118 in) long, each flower 7–10 mm (0.28–0.39 in) long. The sepals are joined at the base, forming a tube about 2 mm (0.079 in) long, the sepal lobes about the same length as the tube. The petals are pink to purple, the standard petal 15–25 mm (0.59–0.98 in) long and 10–15 mm (0.39–0.59 in) wide, the wings crescent-shaped and 7–11 mm (0.28–0.43 in) long, and the keel 7–10 mm (0.28–0.39 in) long with a broad, erect, beak-like tip. Flowering depends on the environment, and the fruit is an elliptic or oblong pod mostly 10–30 mm (0.39–1.18 in) long and 6–7 mm (0.24–0.28 in) wide with the remains of the strongly curved style about 6 mm (0.24 in) long.^{[2][3][4][5][6]}
