Th e genus is divided into four sections defined on mo 叩hological and geographical data.Filij フendula seems to have evolved mainly geographic through speciation during migrations and isolations in in the late Miocene to Pleistocene. Th e main implied migration routes 台om North America to East Asia and farther farther westward via Himalaya and Siberia ,as well as distribution and variability pattems of the species , and their relationships relationships are discussed. A key and a census of the Filipendula species are presen t.
