Solanum

The generic name was first used by Pliny the Elder (AD 23–79) for a plant also known as , most likely S. nigrum. Its derivation is uncertain, possibly stemming from the Latin word , meaning "sun", referring to its status as a plant of the sun. ==Species having the common name "nightshade"==

The species most commonly called nightshade in North America and Britain is Solanum dulcamara, also called bittersweet or woody nightshade (so-called because it is a scandent shrub). Its foliage and egg-shaped red berries are poisonous, the active principle being solanine, which can cause convulsions and death if taken in large doses. Black nightshades (many species in the Solanum nigrum complex, Solanum sect. Solanum) have varying levels of toxins and are considered too toxic to eat by many people in North America and Europe, but young stems and leaves or fully ripened fruit of various species are cooked and eaten by native people in North America, Africa, and Asia. Deadly nightshade (Atropa belladonna) belongs, like Solanum, to subfamily Solanoideae of the nightshade family, but, unlike that genus, is a member of tribe Hyoscyameae (Solanum belongs to tribe Solaneae). The chemistry of Atropa species is very different from that of Solanum species and features the very toxic tropane alkaloids, the best-known of which is atropine. == Taxonomy ==

The following phylogeny of Solanaceae is from Zhang et al. (2025) figure 1B. It is based on a consensus of 500 trees randomly sampled from 1-Mb genomic windows with 200-kb step size. }}}}}} The non-italicized names inside of Solanum refer to the major clade names within Solanum. These names usually include the similarly-named section but do not have taxonomic standing. ==Ecology==

Solanum species are used as food plants by the larvae of some Lepidoptera species (butterflies and moths). ==Toxicity==

Most parts of the plants, especially the green parts and unripe fruit, are poisonous to humans (although not necessarily to other animals), with some species even being deadly. == Uses ==

Many species in the genus bear some edible parts, such as fruits, leaves, or tubers. Three crops in particular have been bred and harvested for consumption by humans for centuries, and are now cultivated on a global scale: • Tomato, S. lycopersicum • Tomato varieties are sometimes bred from both S. lycopersicum and wild tomato species such as S. pimpinellifolium, S. peruvianum, S. cheesmanii, S. galapagense, S. chilense, etc. (such varieties include—among others—Bicentennial, Dwarf Italian, Epoch, Golden Sphere, Hawaii, Ida Red, Indigo Rose, Kauai, Lanai, Marion, Maui, Molokai, Niihau, Oahu, Owyhee, Parma, Payette, Red Lode, Super Star, Surecrop, Tuckers Forcing, V 121, Vantage, Vetomold, and Waltham.) • Potato, S. tuberosum, fourth largest food crop. • Less important but cultured relatives used in small amounts include S. stenotomum, S. phureja, S. goniocalyx, S. ajanhuiri, S. chaucha, S. juzepczukii, S. curtilobum. • Eggplant (also known as brinjal or aubergine), S. melongena Other species are significant food crops regionally, such as Ethiopian eggplant or scarlet eggplant (S. aethiopicum), naranjilla or lulo (S. quitoense), cocona (S. sessiliflorum), turkey berry (S. torvum), pepino or pepino melon (S. muricatum), tamarillo (S. betaceum), wolf apple (S. lycocarpum), garden huckleberry (S. scabrum) and "bush tomatoes" (several Australian species). Ornamentals The species most widely seen in cultivation as ornamental plants are: • Solanum aviculare - (kangaroo apple) • Solanum crispum - (Chilean potato tree) • Solanum laciniatum - (kangaroo apple) • Solanum laxum - (potato vine) • Solanum mammosum - (Nipplefruit, titty fruit, cow's udder, apple of Sodom) • Solanum pseudocapsicum - (Christmas cherry, winter cherry) • Solanum seaforthianum - (Italian jasmine, St. Vincent lilac) • Solanum mauritianum - (woolly nightshade, earleaf nightshade) • Solanum wendlandii - (paradise flower, potato vine) Medicine Several species are locally used in folk medicine, particularly by native people who have long employed them. ==References==
