Family Code: POLYGO Genus Code: REYNO Genus Summary: A genus of about 15 species, perennial herbs, of temperate e. Asia. Ronse Decraene & Akeroyd (1988) and most other recent workers in Polygonaceae treat this group as Fallopia section Reynoutria (Houttuyn) Ronse Decraene, but molecular evidence supports its recognition at genus rank, as a monophyletic genus basal to Fallopia and Muehlenbeckia (Schuster, Reveal, & Kron 2011).
