Datura Linnaeus. Jimsonweed, Thorn-apple.

Key to Datura

A genus of 10-11 species, annual herbs, of sw. United States and Mexico. Several species of Datura are known to have been in our area at the time of first settlement by Europeans. They may have been weeds in native American fields, or grown for their hallucinogenic properties; the common name ‘Jimsonweed’ is a corruption of ‘Jamestown Weed’.
