foetid cassia

Senna tora belongs to the genus Senna and is part of the Fabaceae family. It is a tropical plant that grows wild in many regions and is considered an invasive species in some areas. The species was first described in 1832 and is known by several common names, including foetid cassia and sickle senna. Its native range is in Central America, but it has since spread to various tropical regions. The plant is often mistaken for Senna obtusifolia due to their similar appearance. The name 'tora' is derived from the Sinhala language. The holotype designation has had some confusion in botanical literature, with early type choices being unclear or incorrect.
