Sarcocornia utahensis has also been reported from Arizona and eastern California. No specimens have been seen from these states but it might be expected to occur in both. A vegetative specimen seen from se Oregon is probably S. utahensis.
P. C. Standley (1916) reported the European species Sarcocornia fruticosa (Linnaeus) A. J. Scott [as Salicornia fruticosa Linnaeus] from Louisiana, but no specimens of this species have been seen from North America. The seeds of S. fruticosa are most similar to those of S. utahensis, so it seems possible that Standley mistook a Louisiana collection of S. utahensis for S. fruticosa. Reports of Salicornia virginica and S. perennis from the coast of Texas are mostly referable to Sarcocornia utahensis, so it is probable that S. utahensis occurs more widely on the Gulf of Mexico.
