There has been widespread skepticism about the recognition of two taxa ... 'scandens' and 'cristata'. Desjardins et al. (2023) cast additional doubt based on molecular evidence. We here lump the two taxa ... If recognized, Fallopia cristata has smaller floral parts: perianth 7-10 mm long at maturity (measured from the pedicel joint to the tip) and achenes 2-3.5 mm long, vs. perianth 10-15 mm long at maturity (measured from the pedicel joint to the tip) and achenes 3.5-6 mm long.
