CEGL004752 Saccharum spp. - Panicum verrucosum - (Rhexia spp., Sabatia spp.) Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Plumegrass species - Warty Panicgrass - (Meadowbeauty species, Rose-gentian species) Marsh
Colloquial Name: Southeastern Coastal Plain Pond Marsh (Plumegrass Type)
Hierarchy Level: Association
Type Concept: This vegetation occupies isolated upland depressions in the Coastal Plain of south-central and southwestern Georgia and Alabama. Examples are not connected to surface flow, but are poorly drained. These habitats are classically found on Grady soils, and are called "Grady Ponds," a term whose exact application is uncertain. They appear to be floristically and geomorphologically distinct from both Carolina bays and Georgia limesink ponds. Examples contain Panicum verrucosum, Scirpus cyperinus, Rhexia mariana, Rhexia virginica, Rhynchospora spp., and Carex glaucescens. Additional taxa seen include Hypericum sp., Ludwigia sp., Mecardonia acuminata, Sabatia angularis, Lachnanthes caroliana, Hypericum denticulatum, Viola x primulifolia, Dichanthelium sp., Euthamia sp., Eupatorium capillifolium, Eupatorium compositifolium, Pluchea camphorata, Drosera intermedia, and Ludwigia linifolia?.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association generally fits the many depressions dominated by Saccharum (particularly Saccharum baldwinii) in Francis Marion National Forest; the dominant Sabatia is Sabatia campanulata, not Sabatia angularis, however. Other characteristic forbs are Pluchea rosea, Pluchea odorata, and Xyris floridana (Glitzenstein and Streng 2004). These ponds are floristically and geomorphologically distinct from both Carolina bays and Georgia limesink ponds. On Fort Benning, Georgia (L6 Pond), this or related vegetation grades into that of ~Panicum hemitomon Pondshore Marsh Alliance (A1379)$$, which appears to be in areas of generally longer hydroperiod. More information on this or related vegetation is available from researchers at Ichauway Plantation, Georgia [see also Lynch (1986)]. Additional data may result in the renaming of this association.

Floristics: Examples of this association contain Panicum verrucosum, Scirpus cyperinus, and Carex glaucescens. Additional taxa seen include Hypericum sp., Ludwigia sp., Mecardonia acuminata, Rhexia spp., and Sabatia angularis. Ponds on Fort Benning, Georgia, contain Rhexia mariana, Rhexia virginica, Rhynchospora spp., Lachnanthes caroliana, Hypericum denticulatum, Viola x primulifolia, Dichanthelium sp., Euthamia sp., Eupatorium capillifolium, Eupatorium compositifolium, Pluchea camphorata, Drosera intermedia, and Ludwigia linifolia?. On the Francis Marion National Forest (South Carolina), the dominant Sabatia is Sabatia campanulata, not Sabatia angularis, however. Other characteristic forbs are Pluchea rosea, Pluchea odorata, and Xyris floridana (= Xyris difformis var. floridana) (Glitzenstein and Streng 2004).
Dynamics: The vegetation varies according to hydroperiod which changes seasonally. Standing water is often present during the winter, while many ponds dry up completely during the summer (Lynch 1986); many examples have evidence of fire as well.
Environmental Description: This vegetation occupies isolated upland depressions in the Coastal Plain of south-central and southwestern Georgia (and possibly Alabama) primarily in the Dougherty Plains (Omernik 65g) (EPA 2004), which are not connected to surface flow. These habitats are classically found on the Grady soil series (Typic Paleaquults), and they may also occur on the Pelham soil series (Arenic Paleaquults) (Lynch 1986).
Geographic Range: This vegetation is associated with, but not restricted to, "Grady Ponds." These ponds are found in the Coastal Plain of south-central and southwestern Georgia (and possibly Alabama) and are floristically and geomorphologically distinct from both Carolina bays and Georgia limesink ponds.
