|discussion=<p>Variety hachidyoensis (Makino) Yonekura & H. Ohashi and var. uzenensis (Honda) Yonekura & H. Ohashi are endemic to Japan and are distinguished by differences in leaf size and pubescence. A dwarf alpine form of <i>Fallopia japonica</i> found in Korea also is sometimes recognized as <i></i>var.<i> compacta</i> (Houttuyn) J. P. Bailey. It is shorter (to 8 dm), has reddish perianths, and often is planted as a ground cover.</p><!--
