Comments: Zostera marina, also known as eelgrass, is found in shallow marine waters between New Jersey Coastal County mainland and barrier islands.  Once present from Monmouth County south to Cape May, it is today restricted to Atlantic and Ocean counties due to boat traffic and eutrophication. Fernald determined Northeastern North American specimens belonged to the variety stenophylla because of the strongly nerved leaves.
