Abstract

A comprehensive phylogenetic analysis of the subfamily Polygonoideae (Polygonaceae) indicated that Fagopyrum hailuogouense is a member of Bistorta. Morphological investigations also confirmed that F. hailuogouense is identical to B. pergracilis which is a widely distributed species in E-Asia. F. hailuogouense is here proposed as a synonym (new synonymy) of Bistorta pergracilis. A lectotype for the name Bistorta pergracilis is designated here on a specimen preserved at K (iso lectotype at NY).
