. Botany for agricultural students . Botany. NIGHTSHADE FAMILY 491 very rapidly. The Dodders are parasitic plants and do much damage in Clover, Alfalfa, and Flax fields, where they twine about the plants and grow their roots into their stems and rob them of their food. Nightshade Family (Solonaceae). — This family is the one to which the Irish Potato, Tomato, and Tobacco belong. Some authors give the number of species as about 1700. Both the five sepals and five petals are more or less joined {Fig. 440). The stamens are five and usually inserted on the corolla. The Irish Potato {Solanum tuberosum) is probably the most im- portant plant of this group and Tobacco (Nicotiana Tabacum) next. Some years the potato crop in the United States is more than 300,000,000 bushels. New York is the chief potato growing state, although many potatoes are grown in Michigan, Wisconsin, and Pennsylvania. The Tomato {Lycopersi- cum esculentum), when first introduced from tropical America as an ornamental plant, was considered poison- ous, but now its fruits are important vegetables. In some of the Southern states, as Kentucky, North Caro- lina, and Virginia, Tobacco is one of the leading agricultural products, while in many other states it is grown in considerable quantities. Some other cultivated plants of this family are the Egg Plant, Cayenne Pepper, Petunia, and Belladonna. To this family belong a number of weeds, some of which are quite troublesome. The Black Nightshade {Solanum nigrum.) and Jimson Weed {Datura Stramonium) {Fig. 441) are common.
