Description:
This alliance accommodates seasonally saturated, open-canopied seeps or peatlands of lower and central New England, the Appalachian Plateau of Kentucky, and the Uwharrie Mountains portion of the Piedmont of North Carolina. In this latter example this vegetation is part of a hillside seepage bog complex; the vegetation is patchy with areas of open canopy as well as areas with no canopy. Shrubs may be sparse to dense. Canopy species include ~Acer rubrum var. trilobum, Liquidambar styraciflua, Nyssa sylvatica, Oxydendrum arboreum, Liriodendron tulipifera, Nyssa biflora, Pinus palustris$, and ~Pinus taeda$. ~Morella caroliniensis (= Myrica heterophylla), Gaylussacia frondosa (= var. frondosa), Vaccinium formosum, Viburnum rufidulum, Alnus serrulata$, and ~Photinia pyrifolia (= Aronia arbutifolia)$ occur in the shrub layers. The herb layer may contain ~Andropogon glomeratus, Calamovilfa brevipilis, Symphyotrichum dumosum var. dumosum (= Aster dumosus var. dumosus), Danthonia spicata, Eupatorium leucolepis var. leucolepis, Eupatorium rotundifolium, Hypericum setosum, Osmunda cinnamomea var. cinnamomea, Panicum virgatum var. virgatum, Pogonia ophioglossoides, Polygala lutea, Sarracenia flava, Sarracenia purpurea var. purpurea (= Sarracenia purpurea ssp. venosa), Sarracenia X catesbaei, Scleria triglomerata, Smilax laurifolia, Solidago stricta, Sphagnum$ spp., and ~Xyris ambigua$ among other species. The open woodland seep association described from broad sandstone ridges in the Appalachian Plateau of Kentucky and Tennessee has a very open canopy with ~Acer rubrum, Ilex opaca var. opaca, Oxydendrum arboreum$, and ~Kalmia latifolia$. Some examples lack a canopy and are dominated by shrubs or herbs, but all are placed here. Shrubs include ~Alnus serrulata, Photinia melanocarpa (= Aronia melanocarpa), Ilex verticillata$, and ~Itea virginica$. Ferns and sedges are locally dominant and ~Sphagnum$-dominated pockets are common with ~Sphagnum palustre$ typical. Herbs include ~Carex atlantica, Carex stricta, Carex bromoides ssp. bromoides, Carex leptalea, Chasmanthium laxum$ (on margins), ~Osmunda cinnamomea, Osmunda regalis var. spectabilis, Thelypteris noveboracensis, Woodwardia areolata, Lygodium palmatum, Scirpus cyperinus, Dichanthelium oligosanthes var. scribnerianum, Rhexia$ spp., ~Mimulus$ spp., ~Eupatorium fistulosum$, and ~Lycopodiella appressa$. New England examples contain ~Acer rubrum$ and ~Larix laricina$.
