CEGL004332 Sagittaria kurziana - Potamogeton illinoensis - Vallisneria americana Aquatic Vegetation

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Spring Tape - Illinois Pondweed - American Eel-grass Aquatic Vegetation

Colloquial Name: Florida Spring-run Aquatic Vegetation

Hierarchy Level:  Association

Type Concept: This association occupies large, clear-water, spring-fed streams in the Florida Panhandle, forming vast beds in freshwater "spring runs," sometimes extending downstream into brackish water. These dense beds are dominated by a combination of Sagittaria kurziana, Potamogeton illinoensis, and/or Vallisneria americana. Other characteristic species include Cabomba caroliniana, Ceratophyllum demersum, Zizania aquatica (submersed forms), Egeria densa (exotic), and Hydrilla verticillata (exotic). This vegetation could extend from the East Gulf Coastal Plain into the adjacent Florida peninsula.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The large and distinctive plants of Vallisneria have sometimes been considered a distinct species, Vallisneria neotropicalis (this now regarded as a synonym of Vallisneria americana).
