Salt water
Salt water cordgrass ("Spartina alterniflora") grows along ditches and on the seaside edges of marshes where high tides daily inundate it. Salt meadow cordgrass ("Spartina patens") and spikegrass ("Distichlis spicata") grow in areas less frequently inundated by saltwater, typically closer to dry land. A short form of salt water cordgrass can sometimes be found in the depressions ("pannes") in the higher areas where salt water collects and evaporates, leaving water even higher in salinity than seawater.
