Because of similarity to Fallopia scandens, specimens of F. dumetorum often are misidentified. Consequently, the range of F. dumetorum in North America is unclear; it is probably exaggerated in most floras.
Mature fruiting perianths provide the most reliable characters distinguishing Fallopia dumetorum from F. scandens. European specimens of F. dumetorum, have fruiting perianths that are consistently orbiculate in outline, with wings usually flat and abruptly contracted on the stipelike perianth bases. Fallopia scandens has fruiting perianths that are obovate in outline, with wings undulate and gradually decurrent on the stipelike perianth bases. Additional characteristics reported to distinguish F. dumetorum from F. scandens are its annual habit (F. scandens also is reported to be annual in some of the literature) and more triangular leaf blades with cordate or sagittate bases. In recognizing F. dumetorum, we follow S. T. Kim et al. (2000) and M. H. Kim et al. (2000), who concluded from limited morphological and flavonoid data that the taxa are best treated as distinct species. More detailed studies may prove the two to be conspecific.
