Type Concept: This is a mixed Atlantic white-cedar - red maple swamp of New Jersey, Delaware and Maryland. In addition to Chamaecyparis thyoides and Acer rubrum, other canopy associates include Magnolia virginiana, Nyssa biflora, Nyssa sylvatica, Pinus taeda, and Fraxinus profunda. Ilex opaca occasionally occurs in the subcanopy. The shrub layer is characterized by Vaccinium corymbosum or Vaccinium formosum, Clethra alnifolia, Ilex glabra, Gaylussacia frondosa, Rhododendron viscosum, Persea palustris, Smilax rotundifolia, and Smilax laurifolia. The herbaceous layer may have sparse to moderate cover and includes species such as Osmunda cinnamomea, Mitchella repens, Woodwardia virginica, Sarracenia purpurea, Triadenum virginicum, Pogonia ophioglossoides, Boehmeria cylindrica, Carex collinsii, and Carex folliculata. In canopy openings, Peltandra virginica, Orontium aquaticum, and Iris versicolor may also occur. Sphagnum mosses form a moderately dense to dense bryophyte layer; species include Sphagnum magellanicum, Sphagnum cuspidatum, Sphagnum pulchrum, Sphagnum flavicomans, Sphagnum recurvum, and Sphagnum fallax.
