Datura metel
A wild form of the plant as a distinct species is unknown, with "Datura metel", as currently described, forming essentially a group of ancient cultivars likely attributable to pre-Columbian horticultural practices. Symon and Haegi noted in 1991 the occurrence on the island of Cuba of an apparently wild plant given the name "Datura velutinosa" (no longer an accepted species and now listed as a form of "D. innoxia"), the capsules of which are tuberculate like those of "D. metel".
