Description:
This alliance includes mid-Atlantic maritime forests that occur on the Outer Coastal Plain of South Carolina and North Carolina, on the mainland and on sea islands, on soils with a substantial shell component. Typical canopy trees are ~Carya glabra$ (probably = ~var. megacarpa$), ~Carya cordiformis, Juglans nigra, Quercus austrina, Acer barbatum, Fraxinus americana, Pinus glabra, Ulmus rubra, Quercus virginiana$, and ~Celtis laevigata$. Less commonly, ~Quercus pagoda$ and ~Quercus phellos$ may be present and common. Typical subcanopy trees include ~Acer barbatum, Aesculus pavia var. pavia, Celtis laevigata, Cercis canadensis var. canadensis, Cornus asperifolia, Frangula caroliniana (= Rhamnus caroliniana)$, and ~Ulmus rubra$. Shrubs may include ~Sabal minor, Cornus asperifolia, Rhapidophyllum hystrix$, and ~Ilex vomitoria$. The herbaceous layer is often lush and moderately diverse, including species such as ~Chasmanthium sessiliflorum, Phryma leptostachya, Fleischmannia incarnata (= Eupatorium incarnatum), Smallanthus uvedalius, Verbesina occidentalis, Trillium maculatum, Geranium maculatum, Geum canadense, Thelypteris kunthii, Carex digitalis, Carex godfreyi, Carex calcifugens$, and ~Carex basiantha$. Soils are calcareous or circumneutral, and have a substantial component of shell or shell hash, deposited either naturally or in prehistoric shell middens. Individual occurrences tend to be small, limited by the unusual edaphic conditions, and are highly variable from one occurrence to another, because of edaphic variation, founder effect, and/or disturbance events.
