A, Biology}, month = {Dec}, note = {Modifying the taxonomic system of the genus Filipendula published by JUZEPCZUK or Popov, I intend to admit three subgenera in the genus, viz. Hypogyna, Ulmaria and Filipendula. One of them, Subgen. Ulmaria is subdivisible into four sections, i. e. Schalameya, Albicoma, Sessilia and Ulmaria. The characters used in this classification are mainly concerning with shape of achenes and presence or absence of calyx tubes. If regard Subgen. Hypogyna demarcated by its hypogynous perianths as most primitive, it is elucidable by means of shortening of the ventral margins of achene that the evolutional trend in Filipendula was directed from Subgen. Hypogyna through Sect. Schalameya and Sect. Sessilia towards Sect. Ulmaria or Subgen. Filipendula (Fig. 16). Among the fifteen species accepted in this text, seven belong to Sect. Schala-meya. Moreover they are almost concentrated into rather coastal districts of the Sino-Japanese region, except F. rubra of North America. The reason why they could not extend their areas into the inside of the Continent seems to be attributable to the comparatively primitive structure of their floral organs. The more advanced species such as F. Ulmaria and F. hexapetala have obtained the vast areas of distri-bution, being highly tolerable to the servere continental conditions as well as the subarctic coastal ones. Although the Sino-Japanese region played a great role for speciation not only of Sect. Schalameya but also of Sect. Albicoma or of Sect. Sessilia, their members have been not always prospering. It is worth notice that many of them remain endemic to the small areas or discontinuous as exemplified by F. glaberrima, F. purpurea, F. multijuga, F. angustiloba, F. formosa, F. Tsuguwoi and F. kiraishiensis., Article, Journal of the Faculty of Textile Science and Technology, Shinshu University. Ser.
