Jatropha

Jatropha is a genus of flowering plants in the spurgefamily, Euphorbiaceae. The name is derived from the Greek words ἰατρός (iatros), meaning "physician", and τροφή (trophe), meaning "nutrition", hence the common name physic nut. Another common name is nettles purge. It contains approximately 170 species of succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas). The stems of haat (Jatropha cuneata) are used for basketmaking by the Seri people in Sonora, Mexico. The stems are roasted, split and soaked through an elaborate process. The reddish dye that is often used is made from the root of another plant species, Krameria grayi. Spicy jatropha (J. integerrima) is cultivated as an ornamental in the tropics for its continuously blooming crimson flowers. Buddha belly plant (J. podagrica) was used to tan leather and produce a red dye in Mexico and the southwestern United States. It is also used as a house plant.
