Senna charlesiana is a species of flowering plant in the family Fabaceae and is endemic to Western Australia. It is an erect shrub with cylindrical leaves, sometimes with one or two pairs of cylindrical leaflets, and yellow flowers arranged in pairs or groups of three or four, with ten fertile stamens in each flower.
Senna charlesiana is an erect, compact or straggling shrub that typically grows to a height of up to 2 m (6 ft 7 in), its stems and foliage softly-hairy. The leaves are cylindrical, sometimes flattened, 40–100 mm (1.6–3.9 in) long on a petiole 4–10 mm (0.16–0.39 in) long and about 1 mm (0.039 in) wide, sometimes with one or two pairs of cylindrical leaflets 5–20 mm (0.20–0.79 in) long and about 1 mm (0.039 in) wide. The flowers are yellow and arranged in upper leaf axils in pairs or groups of up to four on a peduncle 10–20 mm (0.39–0.79 in) long, each flower on a pedicel 5–7 mm (0.20–0.28 in) long. The petals are about 12 mm (0.47 in) long and there are ten fertile stamens, the anthers about 3–4 mm (0.12–0.16 in) long. Flowering occurs in winter, and the fruit is a flat pod 50–60 mm (2.0–2.4 in) long.[2][3]
