Description:
This alliance includes open woodland vegetation dominated by ~Pinus rigida$ and either ~Quercus alba$ or ~Quercus stellata$. This alliance currently contains three associations, each very restricted in occurrence, and occurring over ultramafic rocks in the Southern Blue Ridge Mountains. These ~Pinus rigida - Quercus alba$ woodlands typically occur over a cespitose graminoid-dominated understory with little shrub cover. Other canopy and subcanopy trees may include ~Pinus virginiana, Tsuga canadensis, Acer rubrum$, and ~Oxydendrum arboreum$. The dense herbaceous stratum is dominated by ~Andropogon gerardii, Sporobolus heterolepis$, and ~Schizachyrium scoparium$. Common forbs include ~Packera plattensis (= Senecio plattensis), Hexastylis arifolia var. ruthii$, and ~Thalictrum macrostylum$. These woodlands are known from shallow, rocky soils associated with outcrops of serpentinized olivine in the Southern Blue Ridge. These communities are unique and have a restricted range and few known occurrences. Other characteristic species include ~Physocarpus opulifolius, Viburnum nudum var. cassinoides, Vaccinium stamineum, Kalmia latifolia, Rhododendron viscosum, Poa saltuensis, Muhlenbergia glomerata, Danthonia spicata, Danthonia compressa, Sorghastrum nutans, Panicum virgatum, Dichanthelium dichotomum, Dichanthelium boscii, Elymus trachycaulus ssp. trachycaulus, Deschampsia caespitosa, Castilleja coccinea, Carex woodii, Symphyotrichum undulatum (= Aster undulatus), Symphyotrichum laeve (= Aster laevis), Oenothera fruticosa, Thaspium trifoliatum$, and ~Phlox stolonifera$.
