    Bulletin of Botanical Research    2004, 24 (2): 141-145.  
    Abstract323)      PDF(pc) (238KB)(438)       Save
    Syringa was distributed in China,North Korea,Japan and Southeast Europe.China was the distribution center for Syringa.The species were distributed in Southwest,Northwest,North and Northeast China.The hypotheses on some distribution patterns were suggested in this paper based on the flora evolution studies. Syringa originated in Southwest China,and the migration routes were:Southwest-Northwest-North-Northeast China-Korea peninsula-Japan,Southwest China-Central Asia-Europe.There was a remote disjunct distribution for sister species. S.protolaciniata,which was originated in Northwest China,had a close relation with S.xpersica(distributed in Northwest China and Central Asia) and S.vulgaris(only live in Southeast Europe).It meant there existed some close links in the evolution of species. S.pinnatifolia with pinnated leaves was an intermediate species,which had an important role in the evolution study of this genus.Fossil record showed that S.oblata had been distributed in the center of China in Miocene.It was obvious that the evolution and migration from Southwest to Central China had been finished before Miocene.
