Genus: NicotianaView DescriptionDichotomous Key

Common Name: TOBACCO
Habit: Annual to small tree. Leaf: +- basal or not; margin entire, +- wavy or not. Inflorescence: raceme or panicle, terminal; lower bracts leaf-like. Flower: calyx 5-lobed, +- enlarging, not fully enclosing fruit; corolla generally radial, generally funnel-shaped to salverform; stamens 5, equal or 1 smaller. Fruit: septicidal capsule. Seed: many, minute, angled.
Species In Genus: +- 60 species: generally America; Nicotiana tabacum L. widely cultivated, tobacco of commerce. Etymology: (J. Nicot, said to have introduced tobacco to Eur, 1530--1600) Toxicity: Seriously TOXIC to livestock.

Nicotiana sylvestris Speg. & Comes
Habit: Perennial herb 10--15 dm, glandular-puberulent. Leaf: 5--30 cm; basal, lower cauline generally elliptic, tapered to winged petiole; upper +- clasping. Inflorescence: bracts < 40 mm, linear to lanceolate. Flower: calyx 8--15 mm, lobes < tube, +- equal, triangular; corolla narrowly funnel-shaped, white to cream, tube + throat 50--75 mm, limb 15--20 mm wide; stamens unequal, attached below tube middle. Fruit: 12--16 mm.
Ecology: Open, disturbed areas, fields; Elevation: < 200 m. Bioregional Distribution: n CCo, SnFrB; Distribution Outside California: native to South America. Flowering Time: Jul--Oct
Unabridged Note: Plants with long-tapered sepal lobes +- = tube are Nicotiana alata Link & Otto, cultivated for ornamental, waif in fields but evidently not collected in California since 1960.
