It is only found on the wettest loamy or silty soils. Stands are dominated by <i>Pinus palustris</i> and <i>Pinus serotina</i>. The shrub layer is characterized by the presence of <i>Magnolia virginiana</i>; the herbaceous stratum typically contains <i>Sporobolus teretifolius</i> and <i>Carex striata</i>.

It potentially ranges from panhandle Florida northwards to South Carolina, but may be restricted to Florida, southeastern Alabama and Georgia. This type has an emergent overstory canopy dominated or codominated by <i>Pinus serotina</i> and <i>Pinus elliottii var. elliottii</i>. These swamps may occur on strongly acidic, infertile, often peaty soils which are either shallowly inundated or waterlogged during wet seasons. They are usually isolated from more fire-prone flatwoods. The midstory is strongly dominated by <i>Cliftonia monophylla</i> and <i>Cyrilla racemiflora</i>, which tend to exclude invasion of other species, and which strongly suppress herbaceous understory species. Other evergreen species, such as <i>Lyonia lucida</i> and <i>Ilex coriacea</i>, may be common. Overall, species richness is quite low.
Comm #2397	Taxodium distichum - Nyssa ogeche Floodplain Forest » more details accession code: urn:lsid:vegbank.org:commConcept:32701-{F3F0DBD5-1655-444B-BECE-57582AFF8C4E}	NatureServe Biotics 2019	5	This forest type includes wet forests of the East Gulf Coastal Plain in northern Florida that are flooded by river overbank flow, and are dominated by a combination of <i>Taxodium distichum, Nyssa ogeche</i>, possibly with a minor component of <i>Nyssa biflora</i>. <i>Acer rubrum</i> is also typically present, with <i>Planera aquatica</i> and <i>Cephalanthus occidentalis</i>. Other shrub and herb components vary among stands. This community occurs in sloughs and depressions in seasonally flooded Coastal Plain riverine settings.

Comm #2400	Fraxinus americana - Carya ovata / Frangula caroliniana / Helianthus hirsutus Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:36521-{535C229E-AC86-45B5-AE04-4CF831D9E5BD}	NatureServe Biotics 2019	5	This community type is currently known only from a narrow, midslope band of Greenbrier limestone on Little Stone Mountain in Wise County, Virginia, and a narrow band of limestone along the Virginia side of Cumberland Gap National Historical Park. The stand in Wise County, VA and associated limestone outcrops extend for more than 2 km and cover at least 100 ha (240 acres). It is an open to very open forest that locally approaches woodland physiognomy. Maximum tree heights are approximately 23 m, but the majority of trees are &lt;20 m in most areas. The mean cover of canopy and subcanopy trees combined is 60-70%. <i>Fraxinus americana, Carya ovata</i>, and <i>Quercus rubra</i> are the most constant and abundant canopy trees. <i>Carya ovalis</i> is a frequent canopy associate, while <i>Acer saccharum var. saccharum</i> and <i>Quercus alba</i> are infrequent but locally important. The former is also present in the 6- to 10-m tall understory stratum, along with <i>Ulmus rubra, Juniperus virginiana var. virginiana</i>, and representatives of the other canopy species. <i>Cercis canadensis var. canadensis</i> generally dominates the shrub layer, with <i>Frangula caroliniana, Cornus florida</i>, and <i>Celtis occidentalis</i> as more-or-less constant and common components. <i>Ostrya virginiana</i> may also be present. <i>Toxicodendron radicans</i> and <i>Parthenocissus quinquefolia</i> are common woody vines that frequently reach into the shrub stratum. The herbaceous layer is variable. <i>Polymnia canadensis, Helianthus hirsutus, Helianthus microcephalus</i>, and <i>Salvia urticifolia</i> are constant and relatively abundant herbs that assumes great dominance over some areas. <i>Diarrhena americana</i> is inconstant but locally dominates bouldery slopes in massive colonies. Very locally, on the most xeric and rocky microtopographic positions, tree cover is open enough for light-demanding plants more characteristic of "barrens" or "glades" to thrive. Included in this group of localized species are <i>Andropogon gerardii, Oligoneuron rigidum var. rigidum, Liatris aspera var. intermedia, Blephilia ciliata, Polygonum scandens var. cristatum</i>, and <i>Solidago speciosa var. speciosa</i>. Sites are similar to those occupied by <i>~Acer saccharum - Quercus muehlenbergii / Cercis canadensis</i> Forest (CEGL006017)$$ but have a higher mean elevation (688 m [2257 feet]), a more south-facing (versus southwest-facing) aspect, and soils with much higher mean calcium levels (mean = 3523 ppm). Soil moisture regime is subxeric, and habitats have high surficial cover of bedrock outcrops, boulders, and stones (mean cover of all three classes combined = 39%).
