CEGL004333 Vallisneria americana - (Heteranthera dubia) Riverine Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Eel-grass - (Grassleaf Mud-plantain) Riverine Aquatic Vegetation
Colloquial Name: Eel-grass River Channel
Hierarchy Level: Association
Type Concept: Stands of this association consist of aquatic vegetation in rivers of the Piedmont, Central Appalachians, Southern Appalachians, and possibly the Atlantic Coastal Plain. This rooted aquatic vegetation is documented from the channels of the Potomac, Shenandoah, James, Clinch and New rivers. Vallisneria americana and Heteranthera dubia are the dominant species in variable proportions. The extent and distribution of this vegetation type and its alliance are poorly understood. Associated species recorded from various sites include Elodea canadensis, Elodea nuttallii, Myriophyllum spicatum, Najas gracillima, Lemna minor, Justicia americana, Potamogeton foliosus, Potamogeton illinoensis, Potamogeton crispus, Stuckenia pectinata, and Potamogeton nodosus.

Floristics: Stands of this association consist of aquatic vegetation dominated by Vallisneria americana and Heteranthera dubia (= Zosterella dubia) in variable proportions. Associated species recorded from various sites include Elodea canadensis, Elodea nuttallii, Myriophyllum spicatum, Najas gracillima, Lemna minor, Justicia americana, Potamogeton foliosus, Potamogeton illinoensis, Potamogeton crispus, Stuckenia pectinata (= Potamogeton pectinatus), and Potamogeton nodosus.
Dynamics: No Data Available
Environmental Description: Stands of this association are found in shallow waters of large rivers. The extent and distribution of this vegetation type and its alliance are poorly understood. It is found in alluvial rivers of the Piedmont, Central Appalachians, Southern Appalachians, and possibly the Mid-Atlantic Coastal Plain. Such vegetation could possibly occur in the East Gulf Coastal Plain states of Mississippi, Alabama, and Georgia, but no specific observations or data are available to support this possibility.
Geographic Range: This is primarily a Southern and Central Appalachian type, ranging from Maryland, West Virginia, Virginia and Kentucky south possibly to South Carolina. It is doubtfully attributed to the Mid-Atlantic Coastal Plain.
