Abstract: Although five types of floristic elements are generally recognized in the historical plant geography，namely geographical element，genetic element，migration element，historical element and ecological element，it is impossible to analyze all of them because of insufficiency of paleogeographical，paleoclimatic and paleobotanical data now．In this paper an attempt is made to present one aspect of the florogeny of eastern Asiatic flora based on an  analysis of the historical elements of Staphyleaceae，Morinaceae and Caprifoliaceae．All the genera but autochthonous Leycesteria and Zabelia belonging to the three aforementioned families and distributed in this interesting floristic region are tentatively grouped into three categories：the boreal Tertiary element-Lonicera，Kolkwitzia，Weigela and Triosteum； the Tethyan Tertiary element——Acanthocalyx，Morina，Cryptothladia，Euscaphis，Symphoricarpos，Abelia，Linnaea，Dipelta and Heptacodium；and the boreotropical element-Turpina，Staphylea and Tapiscia．Takhtajan's concepts of the boreal Tertiary flora and the  Tethyan Tertiary flora are followed here，while the conception of boreotropical flora is just  the same as that of Wolfe．It means that eastern Asiatic angiospermous flora has three Tertiary precursors．  In the present paper the Miocene is theoretically considered to be a period forming the division between paleoendemic and neoendemic genera of flowering plants in eastern Asiatic flora. In general, the genera appearing before the Miocene are recognized aspaleoendemic, while those appearing in and after the Miocene neoendemic. This is based on the following presumptions: (1) The main body of eastern Asiatic flora seems to be formed in the early Miocene. (2) In the Miocene long dispersal might no longer play an important part of plant migration. Since then the world flora probably underwent a great differentiation and the different local floras were greatly enriched by rapidly developed endemic groups.  (3) From the Miocene to the Pliocene the Himalayan movement was intensified. Not only did the movement drastically affect the geomorphological features, but also greatly changed the whole natural environment of China.Decontaminated thianthrene disproportion.
