(Quercus stellata, Ulmus alata) / Schizachyrium scoparium - Symphyotrichum patens var. patentissimum Wooded Grassland
Reference:
NatureServe Biotics 2019
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 <i>Quercus stellata, Ulmus alata, Carya texana, Fraxinus americana, Pinus echinata</i>, and <i>Juniperus virginiana</i> may be present. <i>Ceanothus herbaceus, Celtis tenuifolia, Crataegus spathulata, Rhus aromatica, Sideroxylon lanuginosum, Symphoricarpos orbiculatus</i>, and <i>Yucca arkansana</i> are present as low shrubs. Perennial grasses and graminoids include <i>Schizachyrium scoparium, Danthonia spicata, Panicum virgatum, Dichanthelium commutatum, Elymus</i> sp., and <i>Scleria oligantha</i>. Forbs include <i>Asclepias hirtella, Asclepias viridiflora, Camassia scilloides, Cheilanthes lanosa, Cheilanthes tomentosa, Coreopsis tinctoria, Croton capitatus, Croton monanthogynus, Croton michauxii var. ellipticus, Echinacea pallida, Eriogonum longifolium var. longifolium, Gamochaeta</i> sp., <i>Glandularia canadensis, Stenaria nigricans, Lechea tenuifolia, Manfreda virginica, Monarda russeliana, Opuntia humifusa, Pycnanthemum tenuifolium, Ruellia humilis, Salvia azurea var. grandiflora, Selaginella arenicola ssp. riddellii, Silphium laciniatum, Solidago</i> sp., <i>Stylosanthes biflora, Tephrosia virginiana, Thelesperma filifolium, Tragia betonicifolia</i>, and <i>Vernonia</i> sp. The inclusion of <i>Symphyotrichum patens var. patentissimum</i> 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.
