Fruit (mericarp) morphology of nine species from section Platygalium of the genus Galium from Russia were examined with light microscope and scanning electron microscope (SEM). Macro- and micromorphological characters, including fruit shape, size, and types of mericarp surface and indumentum are presented. Three types of mericarp surface were observed, glabrous, hairy with either hooked or straight hairs and tuberculate. The results agree with those of Pobedimova (1958), who classified the section Platygalium into three series. The mericarp characters also appear to be useful for species delimitation in this group.
