Senna aciphylla, commonly known as sprawling senna[2] or Australian senna,[3] is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a sprawling shrub with pinnate leaves with eight to twelve pairs of linear to narrowly elliptic leaflets, and yellow flowers in pairs or groups of three.
Senna aciphylla is an erect or sprawling shrub that typically grows to a height of up to 3 m (9.8 ft). Its leaves are pinnate, 30–50 mm (1.2–2.0 in) long on a petiole usually 2–5 mm (0.079–0.197 in) long, with four to eight pairs of linear or narrowly elliptic leaflets 20–25 mm (0.79–0.98 in) long and 1–4 mm (0.039–0.157 in) wide. The edges of the leaflets are usually rolled under, the end of each almost sharply-pointed and there is a stalked gland between each pair of leaflets. The flowers are yellow and arranged in upper leaf axils in pairs or groups of three on a peduncle 20–50 mm (0.79–1.97 in) long, each flower on a pedicel 10–15 mm (0.39–0.59 in) long. The petals are 10–15 mm (0.39–0.59 in) long and there are ten fertile stamens, the longest anthers 4–5 mm (0.16–0.20 in) long. Flowering occurs in spring and summer, and the fruit is a linear pod 60–80 mm (2.4–3.1 in) long.[2][3][4]
