(Strammonium datura.) The popular name of a poisonous weed which grows at the West and South. It bears beautiful flowers, but has a nauseous smell. In the villages on the margins of the Western rivers it is a great annoyance. Its name Jimson is supposed to be a corruption of Jamestown, the place whence it is said to have been brought. It is used in medicine in spasmodic asthma.--Flint's Mississippi Valley.
