A3407 Schoenoplectus tabernaemontani - Pontederia cordata - Panicum hemitomon Basin Marsh Alliance

Type Concept Sentence: Emergent wetland vegetation of basins and lakeshores, which are flooded for long periods of time, mostly dominated by graminoid plants such as Juncus spp., Panicum hemitomon, Schoenoplectus americanus, Schoenoplectus tabernaemontani, and Typha latifolia; broadleaf emergent wetland forbs are also important, such as Pontederia cordata.

Common (Translated Scientific) Name: Softstem Bulrush - Pickerelweed - Maidencane Basin Marsh Alliance

Colloquial Name: Southeastern Basin Marsh

Hierarchy Level:  Alliance

Type Concept: This emergent wetland vegetation is mostly dominated by graminoid plants such as Juncus spp., Panicum hemitomon, Schoenoplectus americanus, Schoenoplectus tabernaemontani, and Typha latifolia. Broadleaf emergent wetland forbs are also important, such as Pontederia cordata. It is found in basins and along lakeshores of the Southeastern Coastal Plain, which are flooded for long periods of time.

Diagnostic Characteristics: Emergent wetland vegetation of basins and lakeshores, which are flooded for long periods of time. These are mostly dominated by graminoid plants such as Juncus spp., Panicum hemitomon, Schoenoplectus americanus, Schoenoplectus tabernaemontani, and Typha latifolia. Broadleaf emergent wetland forbs are also important, such as Pontederia cordata.

Environmental Description:  These are forb wetlands occurring in depressions. This alliance is particularly prevalent in mucky organic soils, of seasonally (or sometimes nearly semipermanently) flooded situations in basin depression wetlands in Florida.
Geographic Range: This alliance occurs on the Southeastern Coastal Plain, most commonly in Florida but also in Georgia and North Carolina.
