Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Threadleaf Beaksedge - Annual Rush Marsh

Colloquial Name: Coastal Plain Limesink Pond (Threadleaf Beaksedge Type)

Hierarchy Level:  Association

Type Concept: This association occupies lower margins of limesinks and other ponds of the Atlantic and Gulf coastal plains of the United States from North Carolina south to Florida and west to Alabama. Stands are dominated by Rhynchospora filifolia and Juncus abortivus. Other characteristic species include Rhynchospora pleiantha, Eleocharis tricostata, Centella erecta, Rhynchospora nitens, and Juncus repens.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Some occurrences may be a mosaic of Dichanthelium-dominated (CEGL004105) and Rhynchospora-dominated (CEGL004131) zones. In some other examples the zones may be more distinctive and spatially separated. At Fort Benning, Georgia, Dichanthelium-dominated pond vegetation seems to predominate over the Rhynchospora filifolia-dominated types, and the latter is not recognized as a distinct association.
