This association is found in the Arbuckle Mountains of Oklahoma (Garvin, Johnston, and Murray counties) and the Lampasas Cutplain and Edwards Plateau of central Texas, where it occurs on shallow soils over limestone mesatops, upper slopes and escarpments. <i>Quercus sinuata var. breviloba</i> is dominant. Other characteristic species may include, within their respective ranges, <i>Bouteloua curtipendula, Bouteloua hirsuta, Bouteloua rigidiseta, Hedeoma drummondii, Hilaria belangeri, Cercis canadensis var. texensis, Engelmannia peristenia, Forestiera pubescens, Fraxinus albicans, Sideroxylon lanuginosum, Ilex decidua, Celtis laevigata var. reticulata, Ulmus crassifolia, Sophora secundiflora, Quercus buckleyi, Polygala lindheimeri, Ptelea trifoliata, Rhus lanceolata, Rhus virens var. virens, Rhus trilobata var. trilobata, Schizachyrium scoparium</i>, and, in more mesic areas, <i>Toxicodendron radicans ssp. eximium, Ungnadia speciosa, Sporobolus vaginiflorus var. ozarkanus, Carex planostachys, Lespedeza texana</i>, and <i>Opuntia engelmannii</i>.

It is considered good habitat for the endangered black-capped vireo (<i>Vireo atricapilla</i>) which prefers an open, primarily deciduous shrubland with dense foliage extending to ground level. |

This association represents graminoid-dominated deep flatwoods ponds of the West Gulf Coastal Plain. These ponds are generally circular or elliptical, flat-bottomed depressions on flat terraces in the Outer Coastal Plain, often in ancient stream channels and sloughs. They tend to occur as inclusions within wetland pine savannas, but may also be bordered by upland depression swamps. Examples generally have a layer of tall wetland grasses and sedges above a layer of semi-aquatic herbs. Plant species dominance varies greatly depending upon water depth and the spread of colonial, rhizomatous species, and may also be related to geographic isolation of individual ponds and variations in local fire regimes. These ponds tend to lack woody plant species, but may contain scattered, stunted <i>Nyssa biflora</i> and stems of <i>Cephalanthus occidentalis</i>. The following species are characteristic of this type: <i>Eriocaulon compressum, Xyris fimbriata, Eleocharis equisetoides, Eleocharis quadrangulata</i>, as well as two additional species, <i>Carex verrucosa</i> and <i>Rhynchospora cephalantha</i>, which are more frequent in other pond types. Some other species frequently found in this type include <i>Eriocaulon compressum, Rhynchospora corniculata, Panicum hemitomon, Ludwigia sphaerocarpa, Xyris laxifolia var. iridifolia</i>, and <i>Sagittaria graminea</i>. Other herbaceous species may include <i>Gratiola brevifolia, Hydrolea ovata, Proserpinaca pectinata, Pluchea rosea, Ludwigia pilosa, Bacopa caroliniana, Xyris</i> sp., and <i>Rhynchospora capitellata</i>. |

This successional association could be found anywhere in the southeastern United States from Virginia to Texas, in the coastal plain or adjacent ecoregions. It includes vine-dominated vegetation that develops following clearcut logging, blowdowns, and possibly other disturbance in wetlands. This vine-shrubland is dominated by <i>Vitis rotundifolia, Nekemias arborea</i>, and <i>Campsis radicans</i>. Other species that are present in the vine/liana stratum include <i>Parthenocissus quinquefolia, Toxicodendron radicans ssp. radicans, Bignonia capreolata, Smilax rotundifolia, Berchemia scandens</i>, and likely others. There may exist a limited canopy of <i>Liquidambar styraciflua, Ulmus americana, Quercus</i> spp., <i>Celtis laevigata, Salix</i> spp., and likely other species. Often the weight of the vine coverage will break the stems of woody species before they attain 5 m in height. A limited shrub stratum that contains canopy species as well as <i>Arundinaria gigantea, Ilex decidua, Lindera benzoin, Morella cerifera</i>, and others may be present. <i>Carex abscondita, Arisaema dracontium, Eupatorium capillifolium, Boehmeria cylindrica, Cryptotaenia canadensis, Carex retroflexa, Carex lupulina, Polygonum</i> spp., <i>Cyperus</i> spp., and other species are present in the sparse herbaceous layer. |

This community occurs on the sandy and peaty, seasonally flooded shores of Lake Drummond (Great Dismal Swamp National Wildlife Refuge) and Outer Coastal Plain vernal ponds in Virginia. <i>Taxodium distichum</i> forms an open canopy (averaging about 50% cover). The shrub stratum is dominated by <i>Cephalanthus occidentalis</i> and seedlings of <i>Taxodium distichum</i>, with <i>Clethra alnifolia, Eubotrys racemosa, Toxicodendron radicans ssp. radicans</i>, and <i>Acer rubrum</i> also present. Herbaceous species typical of forested swamps, such as <i>Triadenum walteri, Bidens discoidea</i>, and <i>Cuscuta compacta</i>, occupy the peaty bases of trees and shrubs. Larger areas of exposed sand support <i>Juncus repens, Eleocharis quadrangulata, Panicum verrucosum, Fuirena pumila, Cyperus polystachyos var. texensis, Cyperus odoratus, Fimbristylis autumnalis, Lindernia dubia, Echinochloa muricata</i>, and <i>Panicum dichotomiflorum</i>. |
