CEGL004426 Acer rubrum var. trilobum / Viburnum nudum var. nudum / Osmunda cinnamomea - Saururus cernuus - Impatiens capensis Seep Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Carolina Red Maple / Possumhaw / Cinnamon Fern - Lizard''s-tail - Orange Jewelweed Seep Forest

Colloquial Name: Piedmont Low-Elevation Headwater Seepage Swamp

Hierarchy Level:  Association

Type Concept: This saturated vegetation is found in seepage areas, often on edges of floodplains or in headwaters of small streams, in the Inner Coastal Plain and Piedmont of North Carolina, South Carolina, Georgia, Virginia, and likely other states. The canopy includes Acer rubrum, Quercus phellos, and possibly other wetland trees. Some examples may contain, or even be codominated by, Nyssa sylvatica or less likely Nyssa biflora. Some herbs found in this association include Saururus cernuus, Impatiens capensis, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Boehmeria cylindrica, Rudbeckia laciniata, Ranunculus recurvatus, and Juncus spp. Some more western examples may contain Chelone glabra and Saxifraga micranthidifolia. Occurrences in South Carolina''s Savannah River drainage are dominated by Carex atlantica ssp. capillacea, Carex debilis var. pubera, Carex debilis var. debilis, and Carex leptalea.

Classification Comments: Vegetation which may fit this concept at Hanging Rock State Park (Stokes County, northwestern Piedmont of North Carolina) has a canopy dominated by Acer rubrum var. trilobum and Liriodendron tulipifera, and a subcanopy containing Ilex opaca var. opaca and Acer rubrum. Shrubs include Viburnum nudum var. nudum, Ilex montana, Aronia arbutifolia, and Gaylussacia frondosa?. The herbaceous layer contains Osmunda cinnamomea, Osmunda regalis var. spectabilis, Woodwardia areolata, Carex intumescens, Chasmanthium laxum, Calamagrostis coarctata, Doellingeria umbellata var. umbellata, Viola x primulifolia, and Chelone cuthbertii (M. Pyne pers. comm. 1997). In Virginia and farther north, related vegetation is treated (depending on soil chemistry) as ~Acer rubrum - Nyssa sylvatica - Magnolia virginiana / Viburnum nudum var. nudum / Osmunda cinnamomea Swamp Forest (CEGL006238)$$ and ~Acer rubrum - Nyssa sylvatica / Ilex verticillata - Vaccinium fuscatum / Osmunda cinnamomea Seep Forest (CEGL007853)$$.

Floristics: The canopy includes Acer rubrum, Quercus phellos, and possibly other wetland trees. Some examples may contain, or even be codominated by, Nyssa sylvatica or less likely Nyssa biflora. Some herbs found in this association include Saururus cernuus, Impatiens capensis, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Boehmeria cylindrica, Chelone glabra, Rudbeckia laciniata, Ranunculus recurvatus, and Juncus spp. Some more montane-influenced examples (e.g., Stokes County, North Carolina) may contain Saxifraga micranthidifolia (Schafale and Weakley 1990). Occurrences in South Carolina''s Savannah River drainage are dominated by Carex atlantica ssp. capillacea, Carex debilis var. pubera, Carex debilis var. debilis, and Carex leptalea (P. Hyatt pers. comm.).

An apparent example at Hanging Rock State Park (Stokes County, northwestern Piedmont of North Carolina) contains Osmunda cinnamomea, Osmunda regalis var. spectabilis, Woodwardia areolata, Carex intumescens, Chasmanthium laxum, Calamagrostis coarctata, Doellingeria umbellata var. umbellata (= Aster umbellatus var. umbellatus), Viola x primulifolia, and Chelone cuthbertii.
