Name: Peltandra virginica - Pontederia cordata Tidal Marsh
Reference: NatureServe Biotics 2019
Description: This freshwater tidal marsh occurs from Maine to Virginia, excluding Rhode Island and New Hampshire. It is codominated by leafy forbs <i>Peltandra virginica</i> and <i>Pontederia cordata</i>. Associated species can include <i>Zizania aquatica, Sagittaria latifolia, Acorus americanus, Polygonum arifolium, Polygonum hydropiperoides, Polygonum sagittatum</i>, and <i>Bidens</i> spp. Species occurring less frequently can include <i>Typha</i> spp. and <i>Impatiens capensis</i>. At the southern end of the range in Virginia, there is a well-marked variant in which <i>Nuphar advena</i> is codominant with <i>Peltandra virginica</i> and <i>Pontederia cordata</i> in variable mixtures. This variant differs from the almost monospecific ~<i>Nuphar advena</i> Tidal Marsh (CEGL004472)$$ in that it occurs on slightly higher landscape positions where the duration of inundation is shorter, supports higher mean species richness, and contains a number of taxa absent from the low intertidal portions of mudflats.
