This broadly defined type is intended as a placeholder for a diversity of communities dominated by mixtures of these three species. It may be further subdivided at a later time. Communities consisting of mixtures of these three shrub species should be considered to be part of this type, unless one of the other, more specific associations defined in this alliance is clearly indicated. |

This association is a deciduous shrubland occurring on heavy-textured saline soils, usually immediately inland from tidal flats, in the vicinity of Laguna Madre in southern Texas and adjacent Tamaulipas, Mexico. Coverage by woody plants, primarily <i>Prosopis glandulosa var. glandulosa</i>, is variable. The growth of <i>Prosopis glandulosa var. glandulosa</i> is sometimes stunted, possibly by high salinity levels and clayey soils. Coverage by tall, coarse, perennial bunchgrasses, particularly <i>Spartina spartinae</i> and less frequently <i>Sporobolus wrightii</i>, is usually high. Other important species include <i>Borrichia frutescens, Prosopis reptans</i>, and <i>Suaeda</i> sp. Other woody species sometimes scattered in this community include <i>Yucca treculeana, Maytenus phyllanthoides, Gymnosperma glutinosum, Karwinskia humboldtiana, Zanthoxylum fagara</i>, and <i>Schaefferia cuneifolia</i>. While <i>Prosopis glandulosa</i> can tolerate low to moderate saline conditions, it is not thought to thrive in salinity levels common in <i>Spartina spartinae</i> grasslands; therefore, it is unexpected to see these two species persisting together. This vegetation may be a disturbance type resulting from heavy grazing and may also occur in areas where the groundwater salinity is increasing. It is thought to occur naturally in the ecotone between <i>Spartina spartinae</i>-dominated grasslands and <i>Prosopis glandulosa</i>-dominated woodlands and possibly in areas where saline surface soils favor <i>Spartina spartinae</i> and a lower salinity water table below the surface allows the establishment of <i>Prosopis glandulosa</i>. |

This vegetation represents ponds, or zones of ponds, dominated by <i>Panicum hemitomon</i> and various perennial grasses and forbs in the East Gulf Coastal Plain and adjacent ecoregions. This broadly defined association was described to cover shallow ponds (or shallow zones of variable ponds) of the East Gulf Coastal Plain, including limesink ponds and other types. <i>Pluchea</i> spp. (<i>Pluchea camphorata, Pluchea rosea</i>) are characteristic. Other characteristic species include <i>Saccharum</i> spp., <i>Scirpus cyperinus, Dichanthelium</i> spp., <i>Panicum</i> spp., and <i>Rhynchospora</i> spp. in outer zones of shorter hydroperiod, and shorter-stature graminoids and forbs such as <i>Centella erecta, Ludwigia</i> spp., <i>Xyris</i> spp., <i>Hydrocotyle</i> spp., <i>Eleocharis</i> spp., and <i>Juncus</i> spp. in zones of longer hydroperiod. Some stands may contain <i>Woodwardia virginica</i>. |
