Name: Peltandra virginica - Pontederia cordata - Sagittaria spp. Oligohaline Tidal Marsh Alliance
Reference: NatureServe Biotics 2019
Description: This alliance comprises vegetation of oligohaline marshes occurring on tidal rivers beyond significant influence by saline waters, as evidenced by the absence of halophytic species. The vegetation is widely variable and characterized by small to large leafy forbs and graminoids. Associations occur at various microtopographic positions, ranging from high marsh to low marsh and tidal flats. <i>Peltandra virginica, Pontederia cordata</i>, and <i>Sagittaria</i> spp. are characteristic and dominant to codominant. Other characteristic species are diverse and numerous, and may include <i>Acorus calamus, Amaranthus cannabinus, Hibiscus moscheutos, Impatiens capensis</i>, and <i>Thelypteris palustris</i>, as well as species of <i>Carex, Polygonum, Sagittaria</i>, and <i>Schoenoplectus</i>. This alliance occurs in coastal areas from Maine to Virginia and may occur in Quebec and maritime Canada.
