Abstract: Macro- and micro-morphological characteristics of fruits in eight species and one variety of the genus Fagopyrum Mill. (Polygonaceae) from China were observed under stereoscope and scanning electron microscope(SEM). Based on the results, the fruits of the species studied are divided into type Ⅰ , Ⅱ and Ⅲ. The fruits of type Ⅰ are triangular-pyramidal; their surface are rugosely reticulate, neither smooth nor shiny. Two species, F. tataricum and F. dibotrys have this fruit type. Those of type Ⅱ are ovoid-triangular-pyramidal; their surface are smooth and shiny, and striately reticulate. Three species, F. esculentum, F. statice and F. lineare, have this fruit type. In type Ⅲ, the fruits are ovoid-triangular-pyramidal; their surface are smooth and shiny, and covered with many warty grains and sparsely finely striate. F. urophyllum, F. gracilipes, F. leptopodum var. leptopodum, and F. leptopodum var. grossii have this fruit type. Judging from the morphological characteristics of fruits, F. dibotrys might be more closely related to F. tataricumthan to F. esculentum.
