(Quercus stellata, Ulmus alata) / Schizachyrium scoparium - Symphyotrichum patens var. patentissimum Wooded Herbaceous Vegetation
Reference:
Southeastern Ecology Working Gro...
Description:
This glade community occurs on the Mazarn Shale and related substrates of the Ouachita Mountains of Arkansas and Oklahoma (including some mixed shale and sandstone examples). The flora has many neutral to basic substrate-preferring components. These glades may occur as extensive areas of herbaceous vegetation with intervening strips of related woodland vegetation. A few stunted individuals of Quercus stellata, Ulmus alata, Carya texana, Fraxinus americana, Pinus echinata, and Juniperus virginiana may be present. Ceanothus herbaceus, Celtis tenuifolia, Crataegus spathulata, Rhus aromatica, Sideroxylon lanuginosum, Symphoricarpos orbiculatus, and Yucca arkansana are present as low shrubs. Perennial grasses and graminoids include Schizachyrium scoparium, Danthonia spicata, Panicum virgatum, Dichanthelium commutatum, Elymus sp., and Scleria oligantha. Forbs include Asclepias hirtella, Asclepias viridiflora, Camassia scilloides, Cheilanthes lanosa, Cheilanthes tomentosa, Coreopsis tinctoria, Croton capitatus, Croton monanthogynus, Croton willdenowii, Echinacea pallida, Eriogonum longifolium var. longifolium, Gamochaeta sp., Glandularia canadensis, Hedyotis nigricans, Lechea tenuifolia, Manfreda virginica, Monarda russeliana, Opuntia humifusa var. humifusa, Pycnanthemum tenuifolium, Ruellia humilis, Salvia azurea var. grandiflora, Selaginella arenicola ssp. riddellii (= Selaginella riddellii), Silphium laciniatum, Solidago sp., Stylosanthes biflora, Tephrosia virginiana, Thelesperma filifolium, Tragia betonicifolia, and Vernonia sp. The inclusion of Symphyotrichum patens var. patentissimum (= Aster patens var. patentissimus) as a nominal indicates a relatively western (e.g., Ouachita) distribution. Lichens are in abundance, hanging from the red-cedars and forming large patches in shady areas. The presence of numerous basophilic elements and the mixed nature of the substrate distinguishes this from sandstone glades.
