Morphology
Plants are dioecious, perennial sub shrubs 0.1–1.5 m tall and form dense colonies. The succulent leaves are opposite and sessile. The small, white flowers of ''Batis maritima'' are self-incompatible and the morphology of the pollen indicate that the plant is wind pollinated. Seeds are 1.1 mm long and 0.8 mm wide and have an extreme low weight (0.5 mg/seed). They have a smooth, very dark and hard walled coating and an elongated lenticular shape. It has been reported that they have germinated after several months of floating in seawater. The primary root branches early in development and is unbranched until the shoot is 10 cm or more in height.Duncan S. Johnson, 1935. ''The Development of the Shoot, Male Flower and Seedling of Batis maritima L.'' Bulletin of the Torrey Botanical Club 62:19-32Geographical distribution and environmental requirements
''Batis maritima'' occurs on both Atlantic and Pacific tropical coasts of the three Americas and the Caribbean Islands. The northern distribution (up to 33º N latitude) appears to be influenced by frost events. Many sites where maritime saltwort occurs are subject to severe tropical storms. It typically occurs at elevations less than 1.0 m above mean sea level and at sites where salinity ranges from 18 to 50 ppt (muddy tidal banks, mangrove swamps, salt-marshes, mud and salt flats). It also grows in soils without salt but is vulnerable to competition from nonhalophytes. ''Batis maritima'' occurs in sites normally subject to minimal sand coverage. Wrack deposits seem to stimulate growth. Maritime saltwort has been reported as an invasive species in Hawaii, where it displaces native species. The ability to produce adequate levels of biomass over a wide environmental range have been well documented.Haddad, and Maher M. Noaman, 2001. "Leaching requirement and salinity threshold for the yield and agronomic characteristics of halophytes under salt stress" ''El-Journal of Arid Environments'' 49:865–874 The plant is not seriously affected by insects, disease, or grazing, but the shoots cannot bear sand coverage.Product use
Leaves occasionally are added to salads in Puerto Rico, it has also been used as a pot herb, puree and picklSeeds
Main component of seeds are carbohydrates. The extremely small starch granule size, could be useful for other food and non food applications, which require small starch granules. Overall low values of soluble sugars, especially sucrose, are found. The seed contains high levels of crude protein. The vast majority of its storage proteins are of the aqueous soluble form. It is also a good source of the essential amino acidsPhysiology
It is recognized as a major colonizer after mangroves are destroyed by hurricanes. Although it is not a water plant, it can endure brief flooding and long periods of waterlogged soils.G. Neson, 1965. ''The shrubs and woody vines of Florida'' Pineapple Press 391, pp. Saltwort grows slowly in soils with high salt concentrations but it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves. Obligate-symbiotic vesicular-arbuscular mycorrhizae (VAM) that colonize the roots indirectly reduce water stress and improve phosphate nutrition.R. E. Koske, 1988. "Vesicular-Arbuscular Myccorrhizae of some Hawaiian USA Dune Plants ''Pacific Science'' 42:217-229References
