Tobacco Nicotiana tabacum, copyright Joachim Müllerchen.

Belongs within: Solanaceae.

Nicotiana, the tobaccos, is a genus of flowering plants, most diverse in the Americas, with funnel-shaped flowers borne in racemes or panicles (Hickman 1993). The leaves of several species, most notably N. tabacum, have a stimulant effect when smoked and they are widely cultivated for this purpose.

Characters (from Hickman 1993): Annual to small tree. Leaves entire. Inflorescence a raceme or panicle, terminal. Flower with calyx five-lobed, more or less enlarging, not fully enclosing fruit; corolla generally radial, generally funnel-shaped to salverform; stamens 5, equal or one smaller. Fruit a capsule. Seeds many, minute, angled.
