The Jatropha genus is a group of flowering plants in the spurge family, Euphorbiaceae. The most well-known species in this genus is Jatropha curcas, which is commonly called the physic nut or Barbados nut. This species is known for its oil-rich seeds, which have a variety of uses.

It is native to Central America, but it has spread to many tropical and subtropical regions worldwide. It is often found in arid and semi-arid regions.

The Jatropha plant is a drought-resistant shrub or small tree that typically grows to heights up to five meters (16 feet). It typically has four to five angled stems and is characterized by its glossy, green leaves and its red, papery bark. The plant produces small yellow or greenish-yellow flowers which are followed by the development of green, inedible fruits that contain up to three seeds.

Jatropha seeds are rich in oil, containing between 30-50% of their total dry weight, which can be extracted and used for various purposes, particularly biodiesel production.
