Persicaria extremiorientalis

This species has been rather cryptic in our flora, closely resembling P. lapathifolia and P. maculosa. It has just recently been detected and is expected to expand in range. 

For a detailed study see Atha, D. E., M. H. Nee & R. F. C. Naczi. 2010. Persicaria extremiorientalis (Polygonaceae) is established in the flora of the eastern United States of America.  J. Torrey Bot. Soc. 137(4):333-338.
