Hierarchy Level: Association
Type Concept: This is apparently the southernmost wetland longleaf community of the West Gulf Coastal Plain, occurring on non-saline soils of the Prairie and Intermediate Terraces of Louisiana and related areas of Texas, with an open canopy of Pinus palustris. Typical soils include Kinder (Typic Glossaqualf), Caddo (Typic Glossaqualf), and Guyton (Typic Glossaqualf). Typical species include Ctenium aromaticum, Muhlenbergia expansa, Aristida palustris, Dichanthelium scabriusculum, Dichanthelium spp., Eleocharis tuberculosa, Rhynchospora elliottii, Panicum rigidulum, Scleria georgiana, Scleria pauciflora, Centella erecta, Helenium drummondii, Rhynchospora gracilenta, Rhynchospora microcarpa, Rhynchospora elliottii, Rhynchospora pusilla, Rhynchospora latifolia, Rhynchospora plumosa, Asclepias longifolia, Chaptalia tomentosa, Aletris aurea, Polygala ramosa, Arnoglossum ovatum, Eryngium integrifolium, Eupatorium leucolepis, Marshallia caespitosa var. caespitosa, Marshallia graminifolia var. cynanthera, Rhexia lutea, Scleria georgiana, Platanthera nivea, Lobelia flaccidifolia, Sabatia campanulata, Schoenolirion croceum, and Eriocaulon texense.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Nominals include several typical species with a primarily or strictly West Gulf Coastal Plain distribution. Bridges (1988) recognizes three subtypes of "Wetland Longleaf Pine Savannah - West Gulf Coastal Plain": Prairie Terrace Savannahs (on pimple mounds); Montgomery Terrace Savannahs (with remnants in Hardin County, Texas); and Flat Bently Terrace Savannahs (intermediate in moisture level).

Environmental Description: This West Gulf Coastal Plain wetland longleaf community occurs on non-saline soils of the Prairie and Intermediate Terraces of Louisiana and possibly related sites in Texas. Typical soils include Kinder (Typic Glossaqualf), Caddo (Typic Glossaqualf), and Guyton (Typic Glossaqualf). This is the matrix longleaf pine-dominated association on the lower terraces of the West Gulf Coastal Plain. This community occurs on some of the outermost terraces of the Coastal Plain, grading into the coastal prairies of Louisiana (L. Smith pers. comm.). Wetter soil inclusion supporting flatwoods ponds may be present throughout.
Geographic Range: This community is found on non-saline soils of the Prairie and Intermediate Terraces of Louisiana and related areas of the West Gulf Coastal Plain of Texas.
