Abstract

Bistorta griffithii and B. suffulta are taxonomically revised. B. griffithii is similar to B. amplexicaulis and B. henryi in the rhizome form, but differs from them in the position of articulation on the pedicel. Polygonum griffithii is confirmed as a valid name preceding a conspecific P. calostachyum. B. suffulta subsp. pergracilis (= Polygonum suffulta var. pergracile) is reduced into B. suffulta var. suffulta. Polygonum suffultoides A. J. Li recently described from Yunnan of southwestern China is reduced to a variety of B. suffulta.
