Summary:The distribution of aquatic vascular plants in two transition areas was studied on the South River, an estuarine branch of the Chesapeake Bay located in Anne Arundel County, Maryland (N 38°54′, W 76°20′). One transition area was near the mouth of the river, where salinities were constantly high due to the proximity of Chesapeake Bay. The other area was at the headwaters of the river, where salinities were lower and without diurnal variation. Temperature, pH, surface currents, and tide levels were measured. Laboratory analyses included three of the major cations in the water, calcium, sodium, and potassium. The dominant species at the mouth of the river were Myriophyllum spicatum, Potamogeton perfoliatus, Elodea Nuttallii, and Spartina alterniflora. The dominant species found at the headwaters were Elodea canadensis, Typha angustifolia, Pontederia lanceolata, Peltandra virginica, and species of the genus Sagittaria.
