Floristics: The vegetation in examples of this type is zoned with an outer ring of trees, a more interior ring of shrubs, herbs and vines, and a central area with or without standing water year round depending on precipitation (Greear 1967, 1986, Wharton 1978). These various regularly occurring zones are all accommodated here. Tree species include Nyssa biflora (which is most abundant and diagnostic), Liquidambar styraciflua, and Acer rubrum var. rubrum (which are typically present but not diagnostic). There are two shrub zones, one dominated by Cephalanthus occidentalis and another slightly higher one dominated by Lyonia lucida (Wharton 1978). Other shrubs that may be present include Viburnum nudum var. nudum, Alnus serrulata, Ilex glabra, Itea virginica, and others. The greenbrier Smilax laurifolia is also present. Herbaceous dominants include Woodwardia virginica and Osmunda regalis var. spectabilis in a fern zone, with Carex glaucescens, Dulichium arundinaceum, and Panicum virgatum (= var. cubense) in a grass-sedge zone. A deeper open-water zone contains Torreyochloa pallida (= Glyceria pallida), Potamogeton pulcher, and Utricularia gibba (= Utricularia biflora). Many plants found in this association are otherwise restricted to the Coastal Plain, at least in Georgia (Greear 1967, 1986). Tennessee examples (if there are any) would lack Lyonia lucida, which is not known from that state.
