This oligohaline to mesohaline marsh of the Mid-Atlantic occurs in silty mud along meanders in tidal rivers and guts in the interiors of extensive marshes where there is significant freshwater input. The vegetation is diverse and variable but is characterized by the consistent presence of <i>Spartina alterniflora, Schoenoplectus robustus (= Scirpus robustus)</i>, and <i>Polygonum punctatum</i>. Other associates include <i>Amaranthus cannabinus, Schoenoplectus tabernaemontani (= Scirpus tabernaemontani), Peltandra virginica, Pluchea odorata, Bidens coronata, Kosteletzkya virginica, Eleocharis palustris, Asclepias incarnata, Schoenoplectus americanus (= Scirpus americanus), Ptilimnium capillaceum</i>, and <i>Echinochloa walteri</i>. <i>Spartina cynosuroides</i> is a common associate in Virginia examples and in some areas of Maryland. |

This Chihuahuan Desert lowland grassland association occurs on gypsum outcrops over a range of elevations from 1160-1860 m (3800-6100 feet). However, most stands occur at elevations below 1520 m (5000 feet) adjacent to or in basin bottom alluvial flats. It is found less frequently on upland hillslope gypsum outcrops. It is known only from the northern Jornada and northern Tularosa basins in central New Mexico. This gypsiferous grassland is characterized by well-represented to abundant Sporobolus nealleyi in association with the perennial forb Calylophus hartwegii. Among the other 22 shrubs recorded, Ephedra torreyana and Artemisia bigelovii are the most prevalent and abundant. Grass diversity is relatively low (5 species) and, other than Sporobolus nealleyi, poorly represented. Forb diversity is moderate (19 species) and includes several gypsophilous species besides Calylophus hartwegii such as Selinocarpus lanceolatus and Mentzelia perennis. |

This alliance includes grasslands occurring over heavy soils on flats within the Trans-Pecos, southwestern Rolling Plains, and northwestern Edwards Plateau of Texas. These grasslands sometimes occupy sites that receive excess run-off from the surrounding landscape and hence represent small, internally drained basin bottoms. ~Prosopis glandulosa$ may be scattered throughout. Other species include ~Buchloe dactyloides, Panicum obtusum, Digitaria californica, Bouteloua$ spp., ~Tridens$ spp., ~Scleropogon brevifolius$, and ~Sporobolus$ spp. These grasslands occur within a matrix of desert shrublands and mixed grasslands. Saline-influenced areas grade into ~Sporobolus airoides$-dominated grassland. |
