CEGL004792 Pinus palustris - (Pinus elliottii) / Ilex vomitoria / Muhlenbergia expansa - Agalinis filicaulis Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Longleaf Pine - (Slash Pine) / Yaupon / Cutover Muhly - Jackson False Foxglove Woodland
Colloquial Name: Southern Mississippi Claypan Longleaf Pine Flatwoods
Hierarchy Level: Association
Type Concept: This association is a saturated longleaf pine woodland found on sandy soil over an underlying clay layer in the East Gulf Coastal Plain. The very open canopy (10-30%) is a mixture of Pinus palustris and Pinus elliottii var. elliottii. Shrubs are sparse, and include Morella caroliniensis, Ilex vomitoria, and Ilex glabra. Scattered Quercus marilandica are also present. The dense ground layer is herb-dominated, with Muhlenbergia expansa, Scleria georgiana, Dichanthelium longiligulatum, and Ctenium aromaticum forming most of the biomass. The herbaceous flora is a mixture of upland and wetland plant species. These include Lophiola aurea, Rhexia alifanus, Lobelia brevifolia, Anthaenantia rufa, Helianthus heterophyllus, Agalinis filicaulis, Bigelowia nudata, Schizachyrium scoparium, Schizachyrium tenerum, Balduina uniflora, Carphephorus pseudoliatris, Chaptalia tomentosa, Rhynchospora latifolia, Rhynchospora chapmanii, Aristida sp., Drosera capillaris, Aletris lutea, Lycopodiella alopecuroides, and Lycopodiella caroliniana. The soils have an upper horizon consisting of about 1.5 dm of fine loamy sand, underlain by a dense, poorly permeable clay layer. This is currently treated as inclusions in the Saucier Soil Series, but it may be described as a new series.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This description is based on examples found on University of Mississippi lands adjacent to the De Soto National Forest. These low-productivity sites are found on the broad flat ridges between stream headwaters; the trees grow very slowly. The sites are saturated in the winter, drying in the summer and fall. Placed in saturated because of the substantial wetland component of the flora. Additional data available from B. Sorrie. Similar vegetation is reported from Louisiana (L. Smith pers. comm.). The full range and variability of this type are incompletely known. This type, at least provisionally, includes the "Longleaf Clay Pine Glade" (or Savanna) described from the De Soto National Forest (J. Moore pers. comm.).

Floristics: The very open canopy (10-30%) is a mixture of Pinus palustris and Pinus elliottii var. elliottii. Shrubs are sparse, and include Morella caroliniensis (= Myrica heterophylla), Ilex vomitoria, and Ilex glabra. Scattered Quercus marilandica are also present. The dense ground layer is herb-dominated, with Muhlenbergia expansa, Scleria georgiana, Dichanthelium longiligulatum, and Ctenium aromaticum forming most of the biomass. The herbaceous flora is a mixture of upland and wetland plant species. These include Lophiola aurea (= Lophiola americana), Rhexia alifanus, Lobelia brevifolia, Anthaenantia rufa, Helianthus heterophyllus, Agalinis filicaulis, Bigelowia nudata, Schizachyrium scoparium, Schizachyrium tenerum, Balduina uniflora, Carphephorus pseudoliatris, Chaptalia tomentosa, Rhynchospora latifolia, Rhynchospora chapmanii, Aristida sp., Drosera capillaris, Aletris lutea, Lycopodiella alopecuroides, and Lycopodiella caroliniana.

Environmental Description: The soils on which this association is found have an upper horizon consisting of about 1.5 dm of fine loamy sand, underlain by a dense, poorly permeable clay layer. These low-productivity sites are found on the broad, flat ridges between stream headwaters; the trees grow very slowly. The sites are saturated in the winter, drying in the summer and fall.
Geographic Range: This saturated longleaf pine woodland association is apparently restricted in distribution to southern Mississippi. Similar vegetation is reported from Louisiana (L. Smith pers. comm.). The full range and variability of this type are incompletely known.
