CEGL007133 Pinus palustris / Quercus geminata / Conradina canescens / Aristida beyrichiana Woodland
Type Concept Sentence: This xeric sandhill association is restricted to coarse sands in lowland areas of the western Florida Panhandle within a few miles of the Gulf Coast; the canopy is dominated by Pinus palustris with a midstory composed of equal parts Quercus laevis, Quercus incana, and Quercus geminata.
Common (Translated Scientific) Name: Longleaf Pine / Sand Live Oak / False Rosemary / Beyrich''s Three-awn Woodland
Colloquial Name: Western Florida Panhandle Xeric Lowland Sandhill Longleaf Pine Woodland
Hierarchy Level: Association
Type Concept: This xeric sandhill association is restricted to lowland areas within a few miles of the Gulf Coast, in the western Florida Panhandle (west of the Apalachicola River). Soils of this association are Entisols; however, they are often only moderately well-drained due to higher water tables and, in some cases, the presence of weak spodic horizons. Surface soils are coarse sands, with very low fine silt content. Pinus palustris dominates the canopy of this association, while the midstory is composed of equal parts Quercus laevis, Quercus incana, and Quercus geminata. The shrub layer is well-developed and diverse and characterized by Conradina canescens, Serenoa repens, and indicators Ilex glabra, Licania michauxii, and Opuntia humifusa. Dominant ground cover bunchgrasses include Aristida beyrichiana, Sorghastrum secundum, and Schizachyrium scoparium.
Diagnostic Characteristics: This type is characterized by its location in the extreme western Florida Panhandle and hence species with ranges restricted to or nearly limited to the western panhandle, including Chrysopsis gossypina ssp. hyssopifolia, Chrysoma pauciflosculosa, Euphorbia discoidalis, and Conradina canescens. It can also be distinguished from other sandhill types in Florida by the presence of mesic and xeric flatwoods species (e.g., Ilex glabra).
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Concept and description are based on 4 plots from the Carolina Vegetation Survey (http://vegbank.org/cite/VB.ds.199702). Plots of this type are included in type XU2 of Carr et al. (2010) (Panhandle Xeric Sandhills), along with those of ~Pinus palustris / Quercus laevis / Licania michauxii / Pityopsis aspera Woodland (CEGL003583)$$. The equivalent coastal fringe sandhills of eastern Georgia and northeastern Florida are represented by the little-documented ~Pinus palustris / Quercus (hemisphaerica, laevis) / Morella cerifera / Aristida beyrichiana Woodland (CEGL004263)$$.

Floristics: The sparse canopy of this association is dominated by Pinus palustris, while the scrub oak layer is composed of equal parts Quercus geminata, Quercus incana, and Quercus laevis. The shrub layer is diverse and well-developed and characterized by Serenoa repens, Conradina canescens, Ilex glabra, Licania michauxii, and Opuntia humifusa; the last three are indicators of this type. The herbaceous layer is codominated by Aristida beyrichiana and Schizachyrium scoparium var. stoloniferum. Particularly diagnostic herbs include Aristida mohrii, Baptisia lanceolata, Chrysopsis gossypina ssp. hyssopifolia (= Chrysopsis hyssopifolia), Dichanthelium dichotomum var. tenue (= Dichanthelium tenue), Euphorbia discoidalis, Mimosa microphylla, Pityopsis aspera, Polygonella gracilis, Rhynchospora megalocarpa, Sorghastrum secundum, Sporobolus junceus, and Triplasis americana.
