Solanaceae (/ˌsɒləˈneɪsi.iː, -ˌaɪ/),[3] commonly known as the nightshades, is a family of flowering plants that includes annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
The family includes a number of commonly collected or cultivated species. The most economically important genus of the family is Solanum, which contains the potato (S. tuberosum), the tomato (S. lycopersicum), and the eggplant (S. melongena). Another important genus, Capsicum, produces both chili peppers and bell peppers. The genus Physalis produces the so-called groundcherries, as well as the tomatillo (Physalis philadelphica) and Physalis peruviana (Cape gooseberry). Alkekengi officinarum (Chinese Lantern) was previously included in the genus Physalis (as Physalis alkekengi), until molecular and genetic evidence placed it as the type species of a new genus.[4][5] The genus Lycium contains the boxthorns and the goji berry, Lycium barbarum. Nicotiana contains, among other species, tobacco. Some other important members of Solanaceae include a number of ornamental plants such as Petunia, Browallia, and Lycianthes, and sources of psychoactive alkaloids, Datura, Mandragora (mandrake), and Atropa bella-donna (deadly nightshade). Certain species are widely known for their medicinal uses, their psychotropic effects, or for being poisonous.[6]
This family has a worldwide distribution, being present on all continents except Antarctica. The greatest diversity in species is found in South America and Central America. Most of the economically important genera are contained in the subfamily Solanoideae, with the exceptions of tobacco (Nicotiana tabacum, Nicotianoideae) and Petunia (Petunia × hybrida, Petunioideae), both of which are used as model organisms.[7][8]
