Datura wrightii differs from Datura inoxia in having wider, 5-toothed (instead of 10-toothed) flowers.
Datura inoxia differs from D. stramonium, D. metel & D. fastuosa in having about 7 to 10 secondary veins on either side of the midrib of the leaf which anastomose by arches at about 1 to 3 mm. from the margin. No anastomosis of the secondary veins are seen in the other 4 major species of Datura.
