CEGL008588 Amphicarpum muehlenbergianum - (Panicum hemitomon) Marsh

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Peanutgrass - (Maidencane) Marsh

Colloquial Name: Peanutgrass - Maidencane Depression Pond

Hierarchy Level:  Association

Type Concept: This depression pond community, dominated by Amphicarpum muehlenbergianum, is found nearly throughout Florida with the exception of south Florida. In addition, Panicum hemitomon may be present or may dominate adjacent zones. This association is intended to accommodate distinctive stands with dominance or at least codominance by Amphicarpum muehlenbergianum. This species is primarily found in Florida and southern Georgia, and is rare or absent in other southeastern states.

Diagnostic Characteristics: No Data Available

Classification Comments: This association is intended to accommodate distinctive herbaceous stands found in Coastal Plain depression ponds with dominance or at least codominance by Amphicarpum muehlenbergianum.

Floristics: Stands of this vegetation are dominated by Amphicarpum muehlenbergianum. In addition, Panicum hemitomon may be present or may dominate adjacent zones. Other herbaceous species are present at much lower cover values, including Rhexia mariana, Eupatorium capillifolium, Eupatorium leptophyllum, Xyris elliottii, Fuirena scirpoidea, Fuirena squarrosa, Lachnanthes caroliana, Rhexia nashii, and Rhynchospora fascicularis (NatureServe Ecology unpubl. data). Shrubs include Hypericum brachyphyllum, Hypericum myrtifolium, Ilex glabra, Ilex myrtifolia, Morella cerifera, and/or Vaccinium darrowii. In addition, scattered Pinus elliottii and/or Taxodium ascendens may be present in some stands. There may be some variability in zonation within ponds; in one pond on the Apalachicola National Forest, a shoreward zone contains more Amphicarpum muehlenbergianum and less Panicum hemitomon, while a central zone of longer hydroperiod was observed with greater Panicum hemitomon dominance, lacking Amphicarpum.

Dynamics:  Fire may be frequent in stands of this association, which is part of a Pinus palustris-dominated landscape.
Environmental Description:  This vegetation is found in depressions of the South Atlantic Coastal Plain, East Gulf Coastal Plain portions of Florida, as wells as the Florida peninsula.
Geographic Range: This association is possible in the South Atlantic Coastal Plain, East Gulf Coastal Plain, and Florida peninsula.
