    • n jatropha A genus of plants of the natural order Euphorbiaceæ, and tribe Crotoneæ, embracing some 68 species belonging to the warmer parts of both hemispheres, but chiefly American. They are monœcious herbs or shrubs with alternate petioled and stipulate leaves, which are entire or palmately lobed. The small flowers are in dichotomous cymes, the fertile toward the center. The male flowers, and sometimes the female, have a corolla with five petals or lobes. The numerous stamens are in two or more series, with their filaments more or less united in a column. The ovary is two- or three-celled, with one seed in a cell. J. Curcas furnishes the seeds known as Barbados nuts, also, on account of their properties, called physic- or purging-nuts. These, with the seeds of J. multifida (called coral-plant), yield the jatropha-oil. J. glauca of the East Indies yields a stimulating oil, used externally. J. urens, var. stimulosa, called spurge-nettle and tread-softly, is a stinging weed of the southern United States. J. podagrica is a curious species sometimes cultivated in conservatories.
