目錄基本的梅西克森林
Dominant trees include tulip-tree (Liriodendron tulipifera), American beech (Fagus grandifolia), bitternut hickory (Carya cordiformis), basswoods (Tilia americana var. americana and var. heterophylla), white ash (Fraxinus americana), black walnut (Juglans nigra), and northern red oak (Quercus rubra). Chinquapin oak (Quercus muehlenbergii), sugar maple (Acer saccharum), black maple (Acer nigrum), and southern sugar maple (Acer floridanum) are important in some of the community types. Shrub and herb layers contain a number of species that are atypical of mountain slopes, such as pawpaw (Asimina triloba), painted buckeye (Aesculus sylvatica), twinleaf (Jeffersonia diphylla), harbinger-of-spring (Erigenia bulbosa), lowland bladder fern (Cystopteris protrusa), and toadshade (Trillium sessile). Widespread herbs include species such as northern maidenhair fern (Adiantum pedatum), hog-peanut (Amphicarpaea bracteata), puttyroot (Aplectrum hyemale), common jack-in-the-pulpit (Arisaema triphyllum ssp. triphyllum), common wild ginger (Asarum canadense), common black cohosh (Actaea racemosa), large yellow lady's-slipper (Cypripedium parviflorum var. pubescens), silvery spleenwort (Deparia acrostichoides), squirrel corn (Dicentra canadensis), Dutchman's breeches (Dicentra cucullaria), showy orchis (Galearis spectabilis), round-lobed hepatica (Anemone americana), green violet (Cubelium concolor), pennywort (Obolaria virginica), aniseroot (Osmorhiza longistylis), broad beech fern (Phegopteris hexagonoptera), mayapple (Podophyllum peltatum), bloodroot (Sanguinaria canadensis), small-flower baby-blue-eyes (Nemophila aphylla), and heart-leaved foamflower (Tiarella cordifolia).
迄今為止分類的五種社群類型按地理和相關基礎進行分隔。通過山谷和皮埃蒙特的石灰岩和其他富含鈣質基材的斜坡，支持了一種獨特的社區類型，特徵是雙葉、矮小龍鼠（ Delphinium tricorne ）、寬葉水葉（Hydrophyllum canadense）和其他春天的短期生長。在詹姆斯市、約克縣和薩福克市的沿岸平原峽谷地下落成三級貝殼沉積，支持了一種特有的社區類型，擁有豐富的南方楓樹和許多值得注意的山脈分裂。
基本米西克森林是富豪灣和斜坡森林的低海拔類似物。除了弗吉尼亞州西北部和中西部山谷的樹木除外，它們出現在非山脈的環境中，包含大量的物種，僅限於弗吉尼亞州低高地。由於重複的伐木和侵入雜草，基本的梅西森林的範圍和生存能力已大大降低。
