Abstract: Fagopyrum crispatifolium J. L. Liu, a new species of the Polygonaceae from Luojishan, Puge, Si-chuan Province, China, is described. This species is closely related to F. gracilipes (Hemsl.) Damm. & Diels, but differs in having leaf blade bullate on the surface, margin corrugated with irregular sinuous-crenate, crenate or crenellate, cyme conferted. It is tetraploid with 2n=4x=32.

Key words: Chromosome number, Fagopyrum, Fagopyrum crispatifolium J. L. Liu, new species, Sichuan, China
