General Discussion

A hybrid between Fallopia japonica and F. sachalinensis.  Recent research indicates extensive backcrossing of F. x bohemica with F. japonica resulting in complex hybrid swarms; and making morphological criteria that distinguish F. x bohemica and F. japonica unreliable in the Northeast, see Gammon et al., 2007.
