[Span., from Ind.] A plant of the Nightshade family, the leaves of which when dried are used for smoking. It was found in America-in use among the Indians-by the Spanish discoverers. The plant is four or five feet high, has a moist, hairy stem, and leaves sometimes two feet long. The leaves are arranged round a singie stalk, and the flowers, which are white and shaped like a funnel, grow at the top of the plant. Only plants grown for seed are allowed to blossom. It is grown in the West Indies, in the southern United States and in other countries. Much is grown in the Philippine Islands. Tobacco leaves rolled up tightly form cigars. The leaves are also twisted, pressed into cake, or cut fine. In making chewing and smoking tobacco in the United States, the leaves are sweetened, colored, and flavored with molasses, liquorice, salt, soda, saltpetre, and aniseed. Snuff is the leaf and stalks ground into powder. Much tobacco is used in the form of cigarettes.
