The Senna tora is an herbaceous annual foetid herb. The plant can grow 30-90 centimetres (12-35 in) tall and consists of alternative pinnate leaves with leaflets mostly with three opposite pairs that are obovate in shape with a rounded tip. The leaves grow up to 3-4.5 centimeters long. The stems have distinct smelling foliage when young. The flowers occur in pairs in axils of leaves with five petals and pale yellow in colour. The stamens are of unequal length. The pods are somewhat flattened or four angled, 10-15 cm long and sickle shaped, hence the common name sickle pod. There are 30-50 seeds within a pod.

Impact

Impact

This species can invade and completely dominate pastures and other disturbed areas such as roadsides, fence lines, creek banks and disturbed areas. They have the potential to become major weeds of many crops within a matter of two or three growing seasons. Sicklepod and sennas are unpalatable to domestic stock. However, cattle and horses will eat mature seed, which can pass through the animal and germinate in dung.
