Madia sativa Molina. Compositae. Madia-Oil Plant.
Western North and South America. This plant is cultivated in Chile, France, Germany and Italy for the sake of the limpid and sweet oil which is expressed from its seeds. This oil is used as a substitute for olive oil. The seeds yield about 41 per cent to analysis and from 26 to 28 per cent to the oil-press, according to Boussingault, whose experiment in 1840 gave 635 pounds of oil and 1706 pounds of oil cake per acre. The plant is easily cultivated, requiring management similar to seed clover, but, owing to the glutinous nature of the stems and stalks, the seeds require to be threshed and sown as soon as the crop is cut, otherwise fermentation injures them.
