CEGL006193 Chrysosplenium americanum Seepage Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Golden-saxifrage Seepage Meadow
Colloquial Name: Golden-saxifrage Forested Seep
Hierarchy Level: Association
Type Concept: This type, which occurs throughout the northeastern United States and possibly adjacent Canada, includes small herbaceous seepage areas with scattered cover of forbs. Herbs are strongly dominant and tend to be relatively diverse, especially where there is greater enrichment. Characteristic species can include Chrysosplenium americanum, Cardamine bulbosa, Circaea alpina, Viola cucullata, Chelone glabra, Glyceria melicaria, Glyceria striata, Cinna arundinacea, Impatiens capensis, Poa paludigena, Carex scabrata, Mimulus ringens, Symplocarpus foetidus, Pilea pumila, Galium triflorum, Saxifraga pensylvanica, Thelypteris noveboracensis, Veratrum viride, Hydrocotyle americana, Onoclea sensibilis, Laportea canadensis, Arisaema triphyllum, Tiarella cordifolia, Carex gynandra, Geum rivale, and the mosses Rhizomnium punctatum, Rhizomnium appalachianum, Brachythecium rivulare, Thuidium delicatulum, Steerecleus serrulatus, and Bryhnia novae-angliae. Typically the community is over-topped by trees and shrubs from the surrounding forest, although large examples will be open.

Classification Comments: This association is broadly classified to include spring runs associated with seeps. Additional data and regional analysis are needed to further refine the classification of this vegetation. Related vegetation in the High Alleghenies of Virginia is treated as ~Carex scabrata - Viola cucullata / Plagiomnium ciliare Seepage Meadow (CEGL006597)$$ and on the Blue Ridge as ~Schoenoplectus acutus - Carex lasiocarpa Marsh (CEGL006358)$$.
