Solanaceae is a family of monopetalous exogenous plants, composed of herbs or shrubs, natives of most parts of the world, and especially within the tropics. They have alternate leaves, terminal or axillary inflorescence, and regular, or nearly regular, monopetalous flowers. They are generally narcotic, tonic and poisonous, although some parts of the plants are cultivated for food (such as the potato, aubergine, chililies and tomato) and others for smoking, such as tobacco.
