CEGL004725 Potamogeton spp. - Ceratophyllum spp. - Elodea spp. Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pondweed species - Hornwort species - Waterweed species Aquatic Vegetation
Colloquial Name: Pondweed - Hornwort - Waterweed Submerged Aquatic Vegetation
Hierarchy Level: Association
Type Concept: This broadly defined type represents vegetation dominated by various floating-leaved and submerged aquatic species (including Potamogeton spp., Ceratophyllum spp., Utricularia spp., and Elodea spp.) from the Cumberlands across to the Atlantic and Gulf coastal plains. Individual stands are typically species-poor and may be dominated by a single species, this leading to any number of apparent dominance types. Until the patterns are better understood, these are all grouped together here.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Additional types may be developed as more information becomes available. Vallisneria americana may be present, and in some cases this would overlap with ~Vallisneria americana Aquatic Vegetation (CEGL002284)$$.

Physiognomy and Structure: No Data Available
Floristics: This association represents submerged aquatic vegetation in the southeastern U.S. Hydrophytes dominate the vegetation, forming 50-80% cover. Composition is variable, but typical plants include Ceratophyllum demersum, Elodea canadensis, Elodea nuttallii, Heteranthera dubia, Justicia americana, Najas gracillima, Podostemum ceratophyllum, Potamogeton crispus, Potamogeton diversifolius, Potamogeton foliosus, Potamogeton nodosus, Stuckenia pectinata (= Potamogeton pectinatus), Utricularia spp., and Vallisneria americana.
At Reelfoot Lake, Tennessee, submerged aquatic vegetation contains variable combinations of Potamogeton diversifolius, Potamogeton nodosus, Ceratophyllum demersum, Stuckenia pectinata, Ludwigia peploides ssp. glabrescens, and Utricularia spp., with Cabomba caroliniana, Heteranthera dubia, and Elodea nuttallii (Guthrie 1989).

Dynamics: The exotic Egeria densa may also be present and may crowd out native components. This association is reported from South Carolina by Aulbach-Smith (pers. comm. 2001).
Environmental Description: This community type is found in shallow to relatively deep (1 m) freshwater basins, marshes, or bays that remain flooded in all but the driest years. Species composition varies with substrate, water depth, water chemistry, turbidity, water temperatures and other factors, but these are poorly understood.
Geographic Range: This aquatic vegetation is found in the southeastern United States, from West Virginia and Tennessee south into Georgia and Mississippi.
