Senna costata is a species of flowering plant in the family Fabaceae and is endemic to northern Australia. It is a shrub or small tree with pinnate leaves with four or five pairs of narrowly elliptic leaflets, and yellow flowers arranged in pairs or groups of five to eight, with ten fertile stamens in each flower.
Senna costata is a shrub or small tree that typically grows to a height of 0.6–3 m (2 ft 0 in – 9 ft 10 in), its stems and foliage softly-hairy. The leaves are pinnate, 40–60 mm (1.6–2.4 in) long on a petiole up to 20 mm (0.79 in) long with four or five pairs of narrowly elliptic leaflets 20–40 mm (0.79–1.57 in) long and 3–8 mm (0.12–0.31 in) wide. The flowers are yellow and arranged in upper leaf axils in groups of five to eight on a peduncle 10–15 mm (0.39–0.59 in) long, each flower on a pedicel 10–15 mm (0.39–0.59 in) long. The petals are 7–10 mm (0.28–0.39 in) long and there are ten fertile stamens, the anthers about 3 mm (0.12 in) long. Flowering occurs in winter and spring, and the fruit is a flat pod 70–80 mm (2.8–3.1 in) long, 8–10 mm (0.31–0.39 in) wide and usually curved.[2][3]
