Discussion

Sesuvium portulacastrum is a widespread and variable subtropical and tropical species to which many names have been applied, particularly to material collected beyond North America (e.g., Argentina and Brazil). Although S. portulacastrum occurs or has been reported in natural habitats on the east coast of North America north to North Carolina, and from ballast north to the Delaware River in Pennsylvania, there are no verified records for this species occurring in western North America north of Mexico, where it occurs northward along the coasts of Sonora and Baja California. All records or collections of S. portulacastrum from desert wetlands of the United States are included in S. verrucosum.

Apparently Sesuvium trianthemoides is known only from the type locality. Additional investigation may reveal this entity should be included in S. maritimum.
