Abstract

Fagopyrum pugense T. Yu (Polygonaceae, Polygonoideae), known only from Luojishan, Puge County, Sichuan Province, China, is described and illustrated. It is closely related to F. gracilipes (Hemsl.) Dammer ex Diels, but differs in the plants having thicker stems and branches with densely erect-villose pubescence, numerous nodes and short internodes, ovate to cordate leaves that are minutely rugose with small pustules, and small achenes. The karyotype studies were also conducted, and the results are presented.
