Description:
Swamp forests dominated by ~Taxodium distichum$ often with a monospecific canopy. Dominance by ~Taxodium$ should be greater than 75%, but hardwoods may be present. Other canopy species that may be present include ~Fraxinus profunda (= Fraxinus tomentosa), Populus heterophylla, Nyssa aquatica$, and possibly others. The subcanopy is usually sparse and may contain ~Planera aquatica, Fraxinus caroliniana$ (in its range), and occasionally ~Acer rubrum$. The shrub and herbaceous layers are very sparse and frequently limited to tree bases and downed logs. Species present include ~Cephalanthus occidentalis, Forestiera acuminata, Bidens discoidea, Carex lupulina, Proserpinaca palustris, Lemna minor, Azolla caroliniana$, and ~Saururus cernuus$. Occurrence of the alliance is possible in suitable habitat anywhere within the range of ~Taxodium distichum$, i.e., the lower Atlantic Coastal Plain from southern Delaware to southern Florida, the lower Gulf Coastal Plain to southeastern Texas, and the Mississippi River Alluvial Plain to southern Illinois. However, it is more commonly recognized outside of, or near the edge of, the range of ~Nyssa aquatica$ which otherwise is frequently codominant with ~Taxodium distichum$. Such areas include: southwestern Arkansas and northwestern Louisiana, southeastern Oklahoma, eastern Mississippi and adjacent Alabama, southern Indiana, peninsular Florida, northeastern Virginia, eastern Maryland and Delaware.
