During a field trip in 2012 to the Veslovskiy peninsula of Kunashir Island in the southern Kurils, 72 species in 24 families of vascular plants were collected. The floristic composition of Veslovskiy was compared with Notsuke of eastern Hokkaido. The general flora is similar between the two regions, except that forest vegetation is lacking in Velslovkiy. The relative dominance of the families; Rosaceae, Ranunculaceae, Ericaceae, and Violaceae in Notsuke can be explained by the presence of the forest vegetation. We could not confirm the forest vegetation in Veslovskiy. Rhinanthus minor and Leontodon autumnalis, which occur on Kunashir, are naturalized plants peculiar to Far Eastern Russia. They may become invaders on Hokkaido. Cakile edentula, on sandy beaches, has recently invaded the southern Kurils via seed dispersal through ocean currents from northern Hokkaido or Sakhalin.
