Senna sericea is a species of flowering plant in the family Fabaceae and is endemic to inland north-western Australia. It is an erect shrub with pinnate leaves, with one or two pairs of egg-shaped leaflets, and yellow flowers arranged in groups of four to twelve, with ten fertile stamens in each flower.
Senna sericea is an erect shrub that typically grows to a height of 0.3–2 m (1 ft 0 in – 6 ft 7 in). Its leaves are pinnate, 20–50 mm (0.79–1.97 in) long including a petiole 5–15 mm (0.20–0.59 in) long, with one or two pairs of egg-shaped leaflets. The leaflets are 10–40 mm (0.39–1.57 in) long and 10–22 mm (0.39–0.87 in) wide, spaced 3–12 mm (0.12–0.47 in) apart when two pairs of leaflets are present. There are up to three sessile, flat glands between the leaflets. The flowers are yellow and arranged in upper leaf axils in groups of four to twelve on a peduncle 20–30 mm (0.79–1.18 in) long, each flower on a pedicel 10–15 mm (0.39–0.59 in) long. The petals are 8–10 mm (0.31–0.39 in) long and there are ten fertile stamens, the anthers 3–4 mm (0.12–0.16 in) long and of different lengths. Flowering occurs in winter, and the fruit is a flat pod about 70 mm (2.8 in) long and 15–25 mm (0.59–0.98 in) wide.[2][3][4]
