Type Concept: This community occupies moist calcareous cliffs in the Ozark region of the Interior Highlands (and is perhaps more widespread). The physiognomy of this community is highly variable. Small and medium trees rooted adjacent to the bluff and on ledges and crevices may form a substantial canopy over the community; typical woody species include Acer saccharum, Acer nigrum, Fraxinus quadrangulata, Fraxinus americana, Cotinus obovatus, Tilia americana var. americana, Quercus muehlenbergii, Juniperus virginiana var. virginiana, and Cladrastis kentukea. Shrubs are often rooted on ledges and in soil mats and can include species such as Hydrangea arborescens, Philadelphus pubescens, Physocarpus opulifolius, Toxicodendron radicans ssp. negundo, Parthenocissus quinquefolia, Staphylea trifolia, Euonymus americanus, and Arundinaria gigantea. Characteristic herbaceous species are Heuchera villosa var. arkansana, Heuchera americana var. hirsuticaulis, Aquilegia canadensis, Pilea pumila, Adiantum pedatum, Aruncus dioicus var. pubescens, Arabis laevigata var. laevigata, Asplenium trichomanes, Asplenium platyneuron, and Cystopteris protrusa.
