Comments
Closely related to, and often synonymized under or considered a variety of, Persicaria punctata (Ell.) Small. However, it is given species status in FNA, and said to differ in having uninterrupted inflorescences, ocreolae usually overlapping and eciliate (sometimes with hairs to 1 mm), and wider leaf blades. Careful field and herbarium studies are needed to determine the status of this species in Virginia, since it was subsumed in P. punctata in earlier, hard-copy editions of the Atlas. It ranges over much of the Atlantic Coastal Plain from NS to FLA, and south into Tropical America.
Habitat
Specimens have been collected from tidal shores, tidal swamps, and seasonally flooded alluvial swamps in seven counties of the southern and central Coastal Plain; often growing in shallow water and abundant where found. The local abundance and wide distribution in relatively common wetland habitats of the region suggests that the species is more numerous than the few collections suggest.
Native Status
Native
