Name: A.1757
Reference: EcoArt 2002
Description: This alliance consists of aquatic vegetation in alluvial rivers and springs dominated by ~Vallisneria americana$. The extent and distribution of this alliance is only partly understood. The habitat includes alluvial rivers, above or extending to the upper limit of tidal influence. Stands are dominated by submergent or emergent plants with only minor floating-leaved components. Stands in the northeastern United States may additionally contain ~Potamogeton perfoliatus, Potamogeton epihydrus, Utricularia$ spp., and ~Eriocaulon aquaticum$. New River occurrences have ~Elodea canadensis, Potamogeton foliosus$, and ~Potamogeton nodosus$. Stands in Florida may have dominance or codominance by ~Sagittaria kurziana$ or ~Stuckenia pectinata (= Potamogeton pectinatus)$. In addition, ~Heteranthera dubia (= Zosterella dubia)$ may be locally abundant. Further study is needed to fully characterize the variability in this alliance.
