Description:
This longleaf pine woodland is described from the hilly and ruggedly dissected uplands of the Homochitto National Forest of Mississippi, where it is apparently restricted to the Lorman soil. The canopy of this community is dominated by some mixture of <i>Pinus palustris, Pinus taeda</i>, and/or <i>Pinus echinata</i>. The precise proportion depends on stand history and current management. In some examples, <i>Pinus taeda</i> is codominant with <i>Pinus echinata</i> limited or absent. Typical subcanopy species include <i>Quercus falcata, Quercus marilandica, Liquidambar styraciflua</i>, and <i>Diospyros virginiana</i>. In managed stands, these hardwoods may be reduced to presence in the tall- or low-shrub strata, along with <i>Acer rubrum</i>. Other shrubs which are typically present include <i>Vaccinium arboreum, Vaccinium elliottii, Ilex decidua, Ilex vomitoria, Ilex opaca, Morella cerifera (= Myrica cerifera), Rhus copallinum, Crataegus marshallii, Baccharis halimifolia</i>, and <i>Gaylussacia dumosa (= var. dumosa)</i>. Woody vines may include <i>Vitis rotundifolia</i> and <i>Gelsemium sempervirens</i>. The herbaceous stratum is diverse, becoming denser with fire management. Typical components include <i>Schizachyrium tenerum, Andropogon virginicus, Dichanthelium</i> spp., <i>Muhlenbergia capillaris, Paspalum floridanum, Gymnopogon</i> sp., <i>Vernonia angustifolia, Liatris pycnostachya, Liatris squarrosa, Solidago odora, Eupatorium album, Eupatorium rotundifolium, Eupatorium semiserratum, Helianthus angustifolius, Helianthus hirsutus, Pityopsis graminifolia var. latifolia</i>?, <i>Symphyotrichum adnatum (= Aster adnatus), Symphyotrichum dumosum (= Aster dumosus), Eurybia hemispherica (= Aster paludosus ssp. hemisphericus), Ionactis linariifolius, Eryngium yuccifolium, Crotalaria purshii, Rhynchosia reniformis, Tephrosia virginiana, Centrosema virginianum, Asclepias verticillata, Asclepias viridiflora</i>?, <i>Rubus flagellaris</i>, and <i>Pteridium aquilinum var. pseudocaudatum</i>. <i>Chasmanthium sessiliflorum</i> may be present, tending to be more plentiful under areas of greater canopy closure. This association is described from hilly and ruggedly dissected uplands of the Homochitto National Forest, where it is apparently restricted to the Lorman soil, a fine, montmorillonitic, thermic vertic medium-acidic Hapludalf. This distinctive pale soil is silt loam in the A horizon, but the AB horizon is a clay loam and the B+ horizon is clay.
