A native of tropical S. America. Datura innoxia is related to Datura meteloides DC., but differs in the ± erect habit, smaller flowers, the larger stigmas and shorter styles. A common plant of roadsides and weedy places, from sea level to 1524 m. The plant parts as in the other Datura species are poisonous. The poisonous seeds are intoxicating and are also used as a cure for hydrophobia (Bhandari, Ind. Desert 269.1978).
