Notes: This plant is covered with glandular hairs, making it sticky to the touch and giving it a pungent, bitter scent; the leaf bases clasp stems; it has a beautiful white to cream or green-tinged flowers; and the the calyx lobes either don't or barely surpass the capsule. This is desert tobacco and the leaves are mild and peppery when smoked. Ethnobotany: Poultice of the leaves applied to cuts, bruises, swellings, and other wounds; smoke was blown into the ear to treat earaches; also used as chew, smoked, and used ceremonially. Etymology: Nicotiana is named for Jean Nicot (1530-1600), the French ambassador to Portugal responsible for introducing tobacco to France in 1560; obtusifolia means obtuse or blunt leaved.
