Name:
Rhynchospora oligantha - Sarracenia spp. - (Aristida beyrichiana, Ctenium aromaticum) - Osmunda cinnamomea / Sphagnum spp. Saturated Herbaceous Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
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.
