Fagopyrum hailuogouense J. R. Shao, M. L. Zhou & Q. Zhang (Polygonaceae), a new species discovered in the Hailuogou National Glacier Forest Park, Tibetan Autonomous Prefecture of Garze, Sichuan Province, China, is described and illustrated. This species is perennial; it is distinguished by its succulent and ligneous rhizomes with numerous adventitious roots, congested nodes on underground rhizomes with sparser nodes on the terrestrial stems, and the smooth epicarp surface of the achene without ornamentation. The smooth achene surface distinguishes F. hailuogouense from the morphologically similar F. cymosum (Trevir.) Meisn.
