Editing Solanum (section)

==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 ([[Vine|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 (botany)|tribe]] [[Hyoscyameae]] (''Solanum'' belongs to tribe Solaneae).<ref>Armando T.
