Eleocharis (elongata, equisetoides) - Rhynchospora tracyi Marsh
Translated Name: (Slim Spikerush, Horsetail Spikerush) - Tracy's Beaksedge Marsh
Common Name: Coastal Plain Spikerush - Beaksedge Marsh
Unique Identifier: CEGL004960
Classification Approach: International Vegetation Classification (IVC)
Summary: This broadly defined type represents vegetation of deeper coastal plain depressional wetlands, typically dominated by aquatic Eleocharis spp., such as Eleocharis elongata, Eleocharis equisetoides and Eleocharis cellulosa, in the Atlantic Coastal Plain and the East Gulf Coastal Plain. Rhynchospora tracyi may also be present. These depressions can be of various geomorphic origins, including limesinks and interdune swales. Additional geographic types may be developed as more specific information becomes available.



Classification

Classification Confidence: Low
Classification Comments: This association is documented on Bon Secour National Wildlife Refuge (Baldwin County, Alabama). Examples on the Apalachicola National Forest (Florida) are found in the deeper parts of limesink depressional wetlands.

Vegetation

Vegetation Summary: This vegetation is typically dominated by aquatic Eleocharis spp., such as Eleocharis elongata, Eleocharis equisetoides, and Eleocharis cellulosa. Rhynchospora tracyi may also be present. An example from the Apalachicola National Forest (Florida) is dominated by Eleocharis equisetoides with Mayaca fluviatilis, Nuphar advena (= Nuphar lutea ssp. advena), and scattered Panicum hemitomon (which dominates an adjacent seasonally flooded zone) (NatureServe Ecology unpubl. data).
