Century Dictionary and Cyclopedia

1. n. The fruit of a garden vegetable, Lycopersicum esculentum, native in tropical South America, now widely cultivated for its esculent fruit in temperate as well as tropical lands; also, the plant itself. The stem is ordinarily weak and reclining, much branched, becoming 4 feet long, but in a French variety—the upright or tree tomato—erect, and sustaining its own fruit. The leaves are interruptedly pinnate, and stain green by contact. It has a small yellow flower, the parts of which are often multiplied in cultivation. The fruit is a berry, normally one- or two-celled and small; under culture, often many-celled and complicated in structure as if by the union of several fruits, large and of a depressed-globose form. A simple pear-shaped form exists; and in one very distinct variety, L. cerasiforme, the cherry- or currant-tomato, the fruit is scarcely larger than a large currant, and is borne in long racemes. The color is commonly some tint of red, sometimes yellow, in one variety nearly white. The tomato-fruit is of a soft, pulpy texture and peculiar slightly acid flavor. It is nutritious and wholesome. with laxative and antiscorbutic properties. The tomato was introduced into Europe early in the sixteenth century; but its esculent use in northern countries began much later. In the United States it was known only as a curiosity till about 1830. It is often called love-apple, a translation of the French pomme d'amour, which is a corruption of the former Italian name pomo dei Mori, the plant having reached Italy through Morocco. From this name aphrodisiac properties have been ascribed to it.
2. n. See Cyphomandra.
