ELEOCHARIS (ELONGATA, EQUISETOIDES) - RHYNCHOSPORA TRACYI SEMIPERMANENTLY FLOODED HERBACEOUS ALLIANCE
Alliance Concept
Summary: This alliance includes the vegetation of deeper Coastal Plain depressional wetlands, typically dominated by aquatic Eleocharis spp., such as Eleocharis elongata, Eleocharis equisetoides, and Eleocharis cellulosa. Rhynchospora tracyi may also be present. The depressions can be of various geomorphic origins, including limesinks and interdune swales.

Alliance Concept
Summary: This alliance includes herbaceous bogs and wetland savannas of the southeastern Coastal Plain ranging from Texas and Oklahoma eastward to North Carolina. Such communities have been variously called hillside seepage bogs, wet prairies, muck bogs, poor fens, sandhill seeps, and other names. Examples are influenced by groundwater seepage and/or seasonally high water tables. Given the large geographic range and extensive species turnover within the Coastal Plain, associations found in this alliance are quite floristically variable. Most types are heavily dominated by wetland herbaceous species. Woody species may occur in scattered clumps and patches in most examples, with density dependent largely on fire frequency and seasonality. In some parts of the distribution of this alliance, especially the Atlantic Coastal Plain, shrubs can be very prominent, even when fire is relatively frequent. Rhynchospora spp. are especially prominent and diverse in most examples; many associations may have as many as ten Rhynchospora spp. present. Carnivorous taxa are also usually present and diagnostic, especially Sarracenia spp. Sarracenia spp. range from dominant or codominant to sparse but diagnostic, and from a single species to several present. The range of species include Sarracenia alata, Sarracenia leucophylla, Sarracenia psittacina, Sarracenia flava, Sarracenia purpurea (= Sarracenia purpurea var. burkii), and Sarracenia rubra. Woody species are Magnolia virginiana, Smilax laurifolia, Morella cerifera (= Myrica cerifera var. cerifera), Morella caroliniensis (= Myrica heterophylla), Morella inodora (= Myrica inodora), Cliftonia monophylla, Cyrilla racemiflora, Clethra alnifolia, Arundinaria gigantea ssp. tecta, and Toxicodendron vernix.

ADIANTUM CAPILLUS-VENERIS SATURATED HERBACEOUS ALLIANCE
Alliance Concept
Summary: Calcareous rock outcrop communities, usually more or less vertical, continuously or seasonally saturated with spray from nearby waterfalls, or wet by wave splash or seepage, with substantial or dominant Adiantum capillus-veneris, and dense cover of bryophytes. Found in Kentucky (and Tennessee) along bluffs of the Cumberland River and its South Fork. At these sites, Boehmeria cylindrica and Lobelia siphilitica are common herbaceous associates; Hydrangea arborescens is a common shrub. Related vegetation is also reported from bluffs of the Cahaba River in central Alabama. Also includes waterfall spray cliff communities along streams in the Edwards Plateau of central Texas. These communities are continuously or at least seasonally saturated by spray, occur on limestone, have Adiantum capillus-veneris as one of the most abundant vascular plants, and dense cover and often also high diversity of bryophytes. In addition, this alliance occurs on seepy limestone exposed on shaded riverbanks, sinkhole sides, and stream ravines in Florida and adjacent states. At these sites, Adiantum capillus-veneris and Thelypteris kunthii are generally the dominant herbs. Decumaria barbara is often a common to codominant festooning vine. Other species may include Aristolochia serpentaria, Selaginella ludoviciana, Carex spp., and others. Bryophytes are abundant and lush, usually dominated by the thallose liverwort Dumortiera hirsuta. Also includes wave splash community on marl outcrops, known from the north shore of Lake Waccamaw, Columbus County, North Carolina.
