The somewhat open canopy is dominated by Acer saccharum, Quercus muehlenbergii, Tilia americana, Fraxinus americana, and occasionally Liriodendron tulipifera, Juglans nigra, Carya cordiformis, Carya ovata, or Carya ovalis. Ostrya virginiana and/or Cornus florida often form a subcanopy. Shrubs can include Hamamelis virginiana, Carpinus caroliniana, Staphylea trifolia, Cornus alternifolia, Ribes americanum, and occasionally Zanthoxylum americanum or Viburnum rafinesquianum. The herb layer is extraordinarily diverse with Packera obovata (= Senecio obovatus), Carex eburnea, Polygala senega, Aquilegia canadensis, Aureolaria flava, Piptatherum racemosum (= Oryzopsis racemosa), Anemone virginiana, Hepatica nobilis var. obtusa (= Hepatica americana), Symphyotrichum patens (= Aster patens), Symphyotrichum undulatum (= Aster undulatus), Triosteum aurantiacum, Thalictrum dioicum, Clematis occidentalis, Asclepias quadrifolia, Arabis canadensis, Geranium maculatum, Penstemon hirsutus, Trillium grandiflorum, Osmorhiza claytonii, Actaea pachypoda, and many others. Bedrock outcrops and boulders are common. Southern species tend to drop out at the northern extent of this type.
