Description:
This bluestem graminoid dolomite glade community is found in the United States in the Ozark region of Missouri and Arkansas. Stands occur on moderate to steep slopes of dissected hills, steep valley slopes above large rivers and streams. Aspect is variable, but typically southern and western. Soils are rapidly drained (seasonally saturated in winter and spring) and shallow (0-40 cm). The parent material is dolomitic (dolostone) bedrock. The vegetation is dominated by medium-tall grasses and forbs, occasionally with stunted trees and shrubs. Stands are dominated Schizachyrium scoparium, Bouteloua curtipendula, Sporobolus heterolepis, occurring with Andropogon gerardii, Rudbeckia missouriensis, Symphyotrichum sericeum (= Aster sericeus), Buchnera americana, Oenothera macrocarpa (= Oenothera missouriensis), Clinopodium arkansanum (= Satureja arkansana), Sporobolus neglectus, Echinacea paradoxa, Evolvulus nuttallianus, Leavenworthia uniflora, Clematis fremontii (= var. riehlii), Centaurea americana, Valerianella ozarkana, Yucca glauca, Eriogonum longifolium, Acacia angustissima, Phyllanthus polygonoides, Cotinus obovatus, Stenosiphon linifolius, Palafoxia callosa, Centaurium texense, Scutellaria bushii, Penstemon cobaea (= var. purpureus), Marshallia caespitosa var. signata, Thelesperma filifolium var. filifolium (= Thelesperma trifidum), Juniperus ashei, Toxicodendron pubescens (= Rhus toxicodendron), and lichens Lecanora muralis, Caloplaca saxicola, Placidium lachneum (= Dermatocarpon lachneum), Psora russellii, Placynthium nigrum.
