Description:
This seasonally flooded wetland occurs on the North Atlantic Coastal Plain in topographically defined basins of New Jersey and possibly Long Island, New York.

The dominant species are <i>Polygonum hydropiper, Polygonum punctatum, Polygonum lapathifolium, Bidens connata, Bidens frondosa</i>, and <i>Leersia oryzoides</i>.
