Description:
These are extremely xeric longleaf pine sandhills, typically with a very sparse <i>Pinus palustris</i> canopy (5-25%). The scrub oak layer is sparse to dense, consisting of <i>Quercus laevis</i>, also often with <i>Quercus hemisphaerica</i> or <i>Quercus geminata</i>. Some occurrences may have <i>Quercus myrtifolia</i> or <i>Quercus margarettiae</i>. Stands of this type are so xeric that <i>Aristida stricta</i> (in more northern examples) and <i>Aristida beyrichiana</i> (in more southern examples) are absent, very sparse, or restricted to moist mesic microsites, such as in associated moist depressions [see, for instance, ~<i>Hypericum reductum / Aristida stricta</i> Dwarf-shrubland (CEGL003954)$$]. The herb layer consists primarily of extreme xerophytes such as <i>Stipulicida setacea, Cnidoscolus stimulosus, Aristida purpurascens var. purpurascens, Aureolaria pectinata, Rhynchospora megalocarpa, Minuartia caroliniana, Dichanthelium ovale var. ovale, Galactia regularis, Euphorbia ipecacuanhae</i> (in more northern examples), <i>Polygonella polygama</i> or <i>Polygonella polygama (= Polygonella croomii), Opuntia humifusa var. humifusa, Bulbostylis ciliatifolia var. coarctata, Vaccinium stamineum</i> (low, whiteleaf form), <i>Cladonia</i> spp., <i>Cladina evansii</i>, and <i>Dicranum condensatum</i>. At Fort Benning, Georgia, <i>Chrysoma pauciflosculosa</i> is a prominent dwarf-shrub. Species diversity is generally very low, with composition varying greatly from site to site. These sites are generally too dry for the wiregrasses, <i>Aristida stricta</i> and <i>Aristida beyrichiana</i>, but these may be present at very low frequencies.
