Euphorbiaceae Juss.: Jatropha L.: Jatropha, a member of family, Euphorbiaceae [subfamily: Crotonideae; tribe: Jatropheae] is a genus of around 75 species. The name is derived from the Greek iatrós (doctor) and trophé (food), referring to its nutritious qualities (when consumed in small amounts).
In 2007 Goldman Sachs cited Jatropha curcas as one of the best candidates for future biodiesel production. It is resistant to drought and pests, and produces seeds containing 27-40% oil, averaging 34.4%. The remaining press cake of jatropha seeds after oil extraction could also be considered for energy production. However, despite their abundance and use as oil and reclamation plants, none of the Jatropha species have been properly domesticated and, as a result, their productivity is variable, and the long-term impact of their large-scale use on soil quality and the environment is unknown. Igbinosa and colleagues (2009) demonstrated potential broad spectrum antimicrobial activity of J. curcas. [source: Wikipedia]
Much like other members of the family Euphorbiaceae, Jatropha plants contain several toxic compounds, including lectin, saponin, carcinogenic phorbol, and a trypsin inhibitor. The seeds of this genus are also a source of the highly poisonous toxalbumin curcin. Despite this, the seeds are occasionally eaten after roasting, which reduces some of the toxicity. Its sap is a skin irritant, and ingesting as few as three untreated seeds can be fatal to humans. [source: Wikipedia]

Pl. go through Jatropha page with images of species in efloraofindia (done by Bhagyashri Ranade ji).
If you find any mis-identification, pl. let us know.
If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let me know.
