Description:
This alliance consists of short-statured, deciduous woodlands in which ~Quercus incana$ is the most characteristic and dominant woody species, although ~Quercus arkansana$ and ~Quercus margarettiae$ may also be present. It is found on ridges of deep(often Grossarenic), sandy soil west of the Mississippi River, in the Upper West Gulf Coastal Plains of eastern Texas, southeastern Oklahoma, northwestern Louisiana, and southwestern Arkansas. Droughty conditions associated with these soils coupled with the effects of natural and managed fire contribute to extreme openness of the vegetation, which may appear to be an herbaceous-dominated community with scattered emergent woody stems. Limited amounts of ~Pinus echinata$ may be present, but this alliance is largely outside the native range of ~Pinus palustris$ and tends to be too xeric and/or too well-burned to allow survival of ~Pinus taeda$. These are open, xeric woodlands with a sparse canopy of the nominal species over open areas dominated by grass, bare sand, or ~Selaginella arenicola ssp. riddellii$. Shrubs occur in dense patches and may include ~Carya texana, Frangula caroliniana, Rhus aromatica, Sideroxylon lanuginosum ssp. lanuginosum, Chionanthus virginicus, Vaccinium stamineum, Vaccinium arboreum$, and ~Sassafras albidum$. Herbaceous species may include ~Schizachyrium scoparium, Opuntia$ sp., ~Clematis$ sp., ~Delphinium$ sp., ~Asclepias$ spp., ~Selaginella arenicola ssp. riddellii, Penstemon murrayanus$, and ~Oenothera heterophylla$. These associations occur in the Middle West Gulf Coastal Plain. Another association occurs in Texas.
