CEGL004127 Panicum hemitomon - Eleocharis equisetoides - Rhynchospora inundata Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Maidencane - Horsetail Spikerush - Narrow-fruit Horned Beaksedge Marsh
Colloquial Name: Atlantic Coastal Plain Maidencane Limesink Pond
Hierarchy Level: Association
Type Concept: This association covers emergent zones of Coastal Plain limesink ponds. Stands are dominated by Panicum hemitomon, Eleocharis equisetoides, and Rhynchospora inundata. Other characteristic species include Eleocharis elongata, Eleocharis robbinsii, Rhynchospora careyana, Eriocaulon compressum, Xyris smalliana, Polygala cymosa, and Juncus abortivus. The use of Eleocharis species as nominals and in the description would indicate that this association is intended to cover deeper ponds, or the deeper zones of those ponds.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Coastal Plain pond communities need reassessment, with additional information from the Deep South and Delmarva-New Jersey-New England. One example of a maidencane pond at Fort Benning, Georgia (L6 Pond), has seasonal codominance by Eleocharis robbinsii and Eleocharis tricostata. It is probably best placed here, but placement between this type (CEGL004127) and CEGL007792 is somewhat problematic because the two associations are not perfectly distinguished from one another.

Floristics: Stands are dominated by Panicum hemitomon, Eleocharis equisetoides, and Rhynchospora inundata. Other characteristic species include Eleocharis elongata, Eleocharis robbinsii, Rhynchospora careyana, Eriocaulon compressum, Xyris smalliana, Polygala cymosa, and Juncus abortivus. Ponds seen on the De Soto National Forest (Jones and Perry counties, Mississippi) have two distinct zones. A less diverse zone of longer hydroperiod (cf. CEGL004127) is dominated by low graminoids and forbs. Eleocharis robbinsii and Eleocharis melanocarpa may exhibit heavy dominance; Carex glaucescens, Juncus repens, and Proserpinaca pectinata are also typically present. A second distinct zone of shorter hydroperiod (cf. CEGL007792) is dominated by Panicum hemitomon with other grasses and graminoids such as Saccharum giganteum, Saccharum brevibarbe, Scirpus cyperinus, Dichanthelium scabriusculum, Panicum rigidulum, Leersia sp., and Rhynchospora glomerata. In addition, Fuirena breviseta, Ludwigia pilosa, and Pluchea rosea are also found there.
Dynamics: No Data Available
Environmental Description: This association represents the emergent zones of Coastal Plain limesink ponds.
