Discussion
Sesuvium maritimum is often overlooked in coastal environments, perhaps due to the small size of some individuals, particularly in the northern portions of its distribution. Nonetheless, this species appears to be infrequent (and possibly in decline) in coastal environments of northern states (e.g., Delaware, Maryland, New Jersey, and New York), where development of the coast has impacted sensitive environments. This species is also present in Kansas and Oklahoma but its distribution in those states is currently not well known.
The name Sesuvium sessile Persoon has been misapplied to this species.
Selected References
None.
