Аннотация:Phylogenetic relationships of East Asian representatives of the genus Filipendula Mill.
(Rosaceae-Rosoideae) as revealed by the analyses of nrITS markers do not completely
coincide with either of the existing taxonomic systems of the genus. The NW American F.
occidentalis (S. Watson) Howell is a strongly isolated species which is not closely related
to the Asian representatives of the genus. This study confirms close phylogenetic relations
between F. tsuguwoi Ohwi (endemic to S Japan) and F. kiraishiensis Hayata (endemic to
Taiwan), as well as their relationships to F. multijuga Maxim. (endemic to Honshu Island,
Japan). This clade also includes the Himalayan species F. vestita Maxim. Two widely
distributed species, F. camtschatica (Pall.) Maxim. and F. glaberrima Nakai, appear to be
related to members of the sect. Albicomae. Filipendula formosa Nakai, a narrow endemic
to S Korea, seems to be basal to this clade. Filipendula yezoensis H. Hara, endemic to
Hokkaido Island, Japan, which is usually synonymized with F. glaberrima, appears to be
weakly differentiated from the latter more widely distributed species.
