Description:
This alliance encompasses a variety of environmental situations with saturated hydrology and a distinctive open canopy of ~Sabal palmetto$. In Florida, this alliance may be represented by a type of open-canopy hydric hammock over organic soil dominated by a combination of ~Sabal palmetto, Quercus virginiana, Acer rubrum, Liquidambar styraciflua$, and ~Quercus nigra$. All the upper woody strata contain prominent ~Sabal palmetto$. Shrubs include ~Ilex cassine, Morella cerifera (= Myrica cerifera), Ilex glabra, Persea palustris, Cornus foemina, Diospyros virginiana$, and ~Vaccinium corymbosum$. Some other sites may consist of wet flatwoods with sand substrates and canopies of cabbage palmetto. In these cases, there is usually a well-developed shrubby stratum, consisting of species such as ~Morella cerifera (= Myrica cerifera var. cerifera)$ and ~Ilex glabra$. The hydrology is seasonally saturated, with rare surface water. On Kiawah Island, South Carolina, woodlands dominated by ~Sabal palmetto$ occupy old dune swales and extensive low flats between old dune ridges. In this vegetation ~Sabal palmetto$ may comprise over 95% of the canopy; the only other tree species which occur are occasional ~Quercus laurifolia, Acer rubrum, Juniperus virginiana var. silicicola (= Juniperus silicicola), Persea$ sp., ~Morella cerifera$, and ~Morus rubra$. This open, glade-like woodland has a dense herbaceous layer containing ~Glyceria septentrionalis, Cladium mariscus ssp. jamaicense (= Cladium jamaicense), Woodwardia virginica, Woodwardia areolata, Hydrocotyle verticillata, Rhynchospora caduca, Carex stipata var. maxima$, and ~Boehmeria cylindrica$. Marsh edge ~Sabal palmetto$ communities with marsh grass understories may also belong in this alliance.
