Persicaria robustior (Small) E.P. Bicknell
Comments
Closely related to, and often synonymized under, 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 likely 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
Fernald and Long no. 9043 at VPI & GH: "Prince George County: muddy tidal shore of James River, Jordan Point." See Rhodora 41:540. A second collection from Surry Co., originally determined as Polygonum densiflorum, is from a similar habitat: "Claremont along James River shore and wooded ravines cut into marl bluff."
