Classification of Vegetation Communities of Maryland: First Iteration
A Subset of the International Classification of Ecological
V. HERBACEOUS VEGETATION
Comments: The northern part of the alliance's range is occupied by Carex striata var. brevis, the southern by Carex striata var. striata. The latter taxon occurs in zones of a depression pond at Fort Benning, Georgia, but not at a sufficient scale to be recognized as an association.
Range: This alliance is found in Florida, North Carolina, South Carolina, Delaware, Maryland, New Jersey, New York, and Virginia. Tyndall et al. (1990) describe Carex striata (as Carex walteriana) communities from Maryland. This alliance is also known from depression meadows in North Carolina and South Carolina, and is assumed to occur in Virginia.

CAREX STRIATA VAR. BREVIS HERBACEOUS VEGETATION
Northern Peatland Sedge Herbaceous Vegetation
Ecological Group (SCS;MCS): Southeastern Coastal Plain Emergent Ponds and Marshes (345-30; n/a)
Concept: This vegetation occupies Coastal Plain depression meadows around the perimeter of Coastal Plain ponds and is dominated by Carex striata var. brevis (= Carex walteriana var. brevis). Examples include vegetation on the outer margins of Coastal Plain pond shores in New York, Maryland and Delaware or in localized swales in the New Jersey pine barrens. The substrate is typically composed of sand and gravel but some community types may occur on organic muck. Carex striata usually occurs in dense stands with few other associates, which may include seedlings of Cephalanthus occidentalis and Acer rubrum, as well as Cladium mariscoides, Rhexia virginica, Bidens frondosa, Rhynchospora macrostachya, Rhynchospora chalarocephala, Fimbristylis autumnalis, Juncus canadensis, Dulichium arundinaceum, and Panicum hemitomon. Sphagnum is often abundant.
