CEGL004660 Juncus roemerianus - Pontederia cordata Tidal Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Needlerush - Pickerelweed Tidal Marsh
Colloquial Name: Tidal Freshwater Marsh (Needlerush Type)
Hierarchy Level: Association
Type Concept: This tidal marsh association occurs in freshwater, wind-tidal settings in coastal marshes of Virginia and North Carolina. Juncus roemerianus is the dominant, but other characteristic species include Pontederia cordata, Thelypteris palustris var. pubescens, Polygonum punctatum, Cladium mariscus ssp. jamaicense, Asclepias lanceolata, Osmunda regalis var. spectabilis, Eleocharis fallax, Sagittaria lancifolia ssp. media, Boehmeria cylindrica, and others. This vegetation is differentiated from other poly- or mesohaline vegetation dominated by Juncus roemerianus by the presence of species characteristic of oligohaline or freshwater conditions, and by the relatively higher species diversity. The substrate is markedly hummock-and-hollow, with relatively firm hummocks and deep, soupy hollows.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This community is known from tributary rivers of Currituck Sound, where Juncus roemerianus may be relictual of more saline and lunar-tidal conditions which presumably prevailed before the closing of the most recent inlet in 1828 (Doumlele 1976, Goldsmith 1977, Priest and Dewing 1991, as cited in Coulling 2002).
