This association is only known from ponds on Macon Ridge in the Mississippi River Alluvial Plain of northeastern Louisiana. The canopy is generally closed and consists of <i>Fraxinus pennsylvanica</i> and <i>Populus heterophylla</i>, with lesser amounts of <i>Ulmus americana</i> (mostly in the less flooded portions), <i>Quercus texana</i>, and <i>Acer rubrum var. drummondii</i>. Typical shrubs are <i>Styrax americanus, Cephalanthus occidentalis</i>, and <i>Ilex decidua</i>. These ponds occur in depressions in an upland ridge and do not receive alluvial flooding. |

This community occurs on flat, massive exposures of Edwards Limestone, in the Edwards Plateau of central Texas. Very shallow pothole depressions accumulate shallow soils. This community is dominated by vernal annuals, including <i>Sedum nuttallianum, Sedum pulchellum</i>, and <i>Sporobolus vaginiflorus var. ozarkanus (= Sporobolus ozarkanus)</i> (and/or likely <i>Sporobolus vaginiflorus var. vaginiflorus</i>). <i>Nostoc commune</i> is common. Vegetative cover generally exceeds 10%, at least during wet periods. |

These are drier Coastal Plain limesink (and other depressional) ponds of the southern Atlantic and East Gulf coastal plains, dominated by <i>Aristida palustris, Andropogon capillipes</i> ('wetland variant'), <i>Andropogon glaucopsis, Andropogon virginicus, Andropogon gyrans var. stenophyllus (= Andropogon perangustatus), Schizachyrium scoparium var. scoparium</i>, and also typically with such species as <i>Saccharum giganteum, Sphagnum</i> spp., and <i>Centella erecta</i>. |

Cynodon dactylon Eastern Herbaceous Vegetation

This association is comprised of improved pastures dominated by <i>Cynodon dactylon</i>, with varying degrees of native composition remaining, on a wide variety of soils and sites. It is currently reported from Florida, Georgia, Oklahoma, and possibly other states, primarily in the Southeastern Coastal Plain, but also in other ecoregions. Vegetation is dominated by the introduced grass <i>Cynodon dactylon</i>, with various remnant native species. Although originally planted, <i>Cynodon dactylon</i> maintains itself spontaneously and is considered weedy or "semi-natural" as opposed to cultivated. Examples from Florida may include the native species <i>Eupatorium capillifolium, Helianthemum carolinianum, Heterotheca subaxillaris, Lechea sessiliflora, Nuttallanthus canadensis, Oenothera laciniata</i>, and <i>Solidago odora var. chapmanii</i>, among others. In addition, <i>Juniperus virginiana var. silicicola, Prunus serotina, Quercus hemisphaerica</i>, and <i>Quercus virginiana</i>, may be present as a sparse tree layer, and a very sparse shrub layer may that include <i>Baccharis halimifolia, Ilex vomitoria, Persea borbonia, Prunus angustifolia, Rubus trivialis, Sabal palmetto</i>, and <i>Sideroxylon tenax</i>. Vines may include <i>Smilax auriculata</i> and <i>Vitis rotundifolia</i>. Stands in Oklahoma may contain <i>Ambrosia artemisiifolia, Amphiachyris dracunculoides</i>, and <i>Melilotus albus</i>. |
