'''''Jatropha''''' is a [[genus]] of approximately 175 [[succulent plant]]s, [[shrub]]s and [[tree]]s (some are [[deciduous]], like ''Jatropha curcas'' L.), from the family [[Euphorbiaceae]]. ''Jatropha'' is native to Central America <ref name="Fairless ">{{cite journal|author=Fairless D.|year= 2007|title=Biofuel: The little shrub that could - maybe| journal=Nature|volume=449|pages=652-655}}</ref>, and has become [[Naturalisation (biology)|naturalized]] in many tropical and subtropical areas, including [[India]], [[Africa]], and [[North America]]. Originating in the [[Caribbean]], the jatropha was spread as a valuable [[hedge]] plant to Africa and [[Asia]] by [[Portugal|Portuguese]] traders. The mature small trees bear male and female [[inflorescence]], and do not grow very tall.
+
Juice milky: lvs. alternate, simple, usually palmately lobed, sometimes pinnate and entire: fls. monoecious, rarely dicecious, usually with petals; sepals 5, more or less connate at base, imbricate; stamens about 10, in 2 or more whorls, some, at least, with the filaments connate; ovary 2-5 celled, 1 ovule in each cell: fr. a caps.— About 150 species, chiefly in the tropics of Amer. and Afr. Related to Hevea and Aleurites.
  
−
The hardy jatropha is resistant to [[drought]] and [[pest]]s, and produces [[seed]]s containing up to 40% oil. When the seeds are crushed and processed, the resulting oil can be used in a standard [[diesel engine]], while the residue can also be processed into [[biomass]] to power electricity plants.<ref>[http://www.timesonline.co.uk/tol/news/world/article2155351.ece Poison plant could help to cure the planet] ''Times Online'', 28 July 2007.</ref>
+
Most of the species of Jatropha are tropical shrubs, but several low or herbaceous species extend into the southern United States. One, the spurge nettle, J, stimulosa, Michx. (Cnidoscolus stimulosus, Gray), is a stinging weed of sandy soil in the South, with white tubular calyx. A related species J. aconitifolia, is planted for hedges in Central America. Many species have found use in medicine chiefly as local or popular remedies. The oil of J. Curcas, for which the plant is cultivated in tropical America, is used as a purgative and also for cooking, soap-making and the like. In Mexico the seeds are reported to be eaten like peanuts. A few years ago J. gossypifolia attracted some attention as a remedy for leprosy.

[[Goldman Sachs]] recently cited ''[[Jatropha curcas]]'' as one of the best candidates for future biodiesel production.<ref>[http://online.wsj.com/article/SB118788662080906716.html?mod=googlenews_wsj Jatropha Plant Gains Steam In Global Race for Biofuels]</ref> However, despite its abundance and use as an oil and [[Land reclamation|reclamation]] plant, none of the ''Jatropha'' species have been properly [[domestication|domesticated]] and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown. <ref name="Fairless"/>

Most of the species are adapted to sandy loam soil. They grow readily from seeds, and cuttings from hard young branches can be rooted in sand with bottom heat if dried somewhat before bedding.

Currently the oil from ''[[Jatropha curcas]]'' [[seed]]s is used for making [[biodiesel]] fuel in [[Philippines]], promoted by a law authored by Philippine senators Miriam Defensor-Santiago and Miguel Zubiri. Likewise, jatropha oil is being promoted as an easily grown biofuel crop in hundreds of projects throughout India and other developing countries. <ref name="Fairless"/> <ref>http://www.worldagroforestrycentre.org/news/default.asp?NewsID=75F25096-4E40-4437-B445-37AD534D033F</ref> The rail line between [[Mumbai]] and [[Delhi]] is planted with Jatropha and the train itself runs on 15-20% [[biodiesel]]. <ref name="Fairless"/> In Africa, cultivation of jatropha is being promoted and is grown successfully in countries such as Mali. <ref>{{cite news |first= |last= |authorlink= |coauthors= |title=Mali’s Farmers Discover a Weed’s Potential Power |url=http://www.nytimes.com/2007/09/09/world/africa/09biofuel.html?em&ex=1189483200&en=b8f0eb75c65f04f3&ei=5087%0A |quote=But now that a plant called jatropha is being hailed by scientists and policy makers as a potentially ideal source of biofuel, a plant that can grow in marginal soil or beside food crops, that does not require a lot of fertilizer and yields many times as much biofuel per acre planted as corn and many other potential biofuels. By planting a row of jatropha for every seven rows of regular crops, Mr. Banani could double his income on the field in the first year and lose none of his usual yield from his field. |publisher=[[New York Times]] |date=[[September 9]], [[2007]] |accessdate=2007-08-21 }}</ref>

* ''[[Jatropha curcas]]'', also called '''physic nut''', is used to produce the non-edible Jatropha oil, for making candles and [[soap]], and as a feedstock for producing [[biodiesel]]. Prior to pressing, the seed can be shelled with the [[Universal Nut Sheller]] which reduces the arduous task of removing the seeds from the shell. This is historically done by hand. Once the seeds have been pressed, the remaining cake can be used as feed in [[digester]]s and gasifiers to produce biogas for cooking and in engines, or be used for fertilizing, and sometimes even as animal [[fodder]]. The whole seed (with oil) can also be used in digesters to produce biogas. Extracts have an anti-[[tumor]] activity. The seeds can be used as a remedy for [[constipation]], wounds can be dressed with the [[sap]], and the boiled leaves remedy [[malaria]] and [[fever]].  Large plantings and nurseries have been undertaken in [[India]] by many research institutions, and by women's [[self-help]] groups who use a system of [[microcredit]] to ease poverty among semi-literate Indian women.

Jatropha is a genus of approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas L.). The name is derived from Greek, and has the common name physic nut. Jatropha is native to Central America[1] and has become naturalized in many tropical and subtropical areas, including India, Africa, and North America. The mature small trees bear separate male and female flowers, and do not grow very tall. As with many members of the family Euphorbiaceae, Jatropha contains compounds that are highly toxic.

The hardy Jatropha is resistant to drought and pests, and produces seeds containing 27-40% oil.

Cultivation

Outdoors: likes moderately rich soil, with humus, and some grit for good drainage. Plant in full sun.

Indoors under glass: 2 parts potting mix (soil based) to one part grit and one part leaf mold. Give strong light, but protect from hot sun under glass. Water moderately in Spring/Summer, with monthly fertilizer, and keep very dry in Fall/Winter.

Propagation

Seed should be sown in Spring or Summer at 74F (25C).

Pests and diseases

Susceptible to mushroom root rot, rust, fungal leaf spot, scale insects, mealybugs.

Species

Jatropha gossipifolia in Hyderabad, India.
Jatropha multifida
Jatropha podagrica in Hyderabad, India.

Species of Jatropha include:

  • Jatropha cuneata limberbush, whose stems are used for basketmaking by the Seri people in Sonora, Mexico, who call it haat.
  • Jatropha curcas, also known as physic nut, piñoncillo and Habb-El-Melúk, is used to produce the non-edible Jatropha oil, for making candles and soap, and as a feedstock for producing biodiesel.
  • Jatropha gossypifolia, also called bellyache bush: its fruits and foliage are toxic to humans and animals. It is a major weed in Australia.
  • Jatropha integerrima Jacq., or spicy jatropha: ornamental in the tropics, continuously crimson, flowers almost all year.
  • Jatropha multifida L., or coral plant: bright red flowers, like red coral, charactertised by strongly incised leaves.
  • Jatropha podagrica or buddha belly plant or bottleplant shrub 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.

Synonyms -- This genus is also known as: Adenorhopium Rchb., Adenoropium Pohl, Aamanakku / Kaattaamanakku Tamil, India, Castiglionia Ruiz & Pav., Collenucia Chiov., Curcas Adans., Jarak Indonesia, Jatropa Scop., orth. var., Loureira Cav., Mesandrinia Raf., Mesandrinia Ortega, Zimapania Engl. & Pax, Nkran Dedua, Pourghère French term, Pulga, Tempate

Toxicity

Characteristic of many members of the family Euphorbiaceae, Jatropha plants contain several toxic compounds, including lectin, saponin, carcinogenic phorbol, and a trypsin inhibitor. 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. In 2005 Western Australia banned Jatropha gossypifolia as invasive and highly toxic to people and animals.
