Reference:

Description:
These are forests of steep, protected coves and slopes at the lower elevations (below 610 m [2000 feet]) of the Southern Appalachians and upper Piedmont, containing a significant component of species associated with high-base status substrates. They share species in common with other Southern Appalachian cove forests, but are distinguished by occurring at relatively low elevations ((305-760 m [1000-2500 feet])) and by the presence of strongly calciphilic species such as <i>Asplenium rhizophyllum, Aquilegia canadensis, Cystopteris protrusa, Diplazium pycnocarpon, Trillium simile, Trillium discolor</i>, and <i>Collinsonia verticillata</i>. Common canopy species include <i>Tilia americana var. heterophylla, Liriodendron tulipifera, Fraxinus americana, Quercus rubra</i>, and <i>Aesculus flava</i>. Other species in the canopy and subcanopy include <i>Ulmus rubra, Juglans nigra, Betula lenta, Carya cordiformis, Halesia tetraptera</i>, and <i>Cornus florida</i>. <i>Acer saccharum</i> is generally not a constant component in these forests. The shrub stratum can be diverse, but the coverage is often quite sparse. Typical shrubs include <i>Hydrangea arborescens, Lindera benzoin, Calycanthus floridus, Philadelphus hirsutus, Philadelphus inodorus</i>, and <i>Rhododendron maximum</i>. The herbaceous stratum is dense, lush, and diverse. Some of the more characteristic species include <i>Sanguinaria canadensis, Cystopteris protrusa, Viola canadensis, Caulophyllum thalictroides, Hydrophyllum canadense, Trillium cuneatum, Asplenium rhizophyllum, Dicentra cucullaria, Tradescantia subaspera, Asarum canadense, Carex plantaginea, Hybanthus concolor, Trillium simile, Aquilegia canadensis, Carex austrocaroliniana, Deparia acrostichoides, Diplazium pycnocarpon, Trillium rugelii</i>, and <i>Trillium luteum</i>.
