New examples of Biogeographical Evolution in Migration of Southwest China-Central China-East China Flora

It was found that Lonicera hemsleyana in East China and recorded specimen L. gynochlamydea in Zhejiang province were highly similar to L. webbiana and L. gynochlamydea in Central China in terms of vegetative organs, such as branches and leaves, but the extent of fusion of neighboring two calyx tubes (along with ovaries) of the paired flowers were very different, which was phytogeographically consistent with their geographical distributions. These two groups of taxa were two pairs of geographical substitutes, which forming through the migration from west to east. Their taxonomic was revised as follows: L. hemsleyana was actually a subspecies of L. webbiana, L. webbiana subsp. hemsleyana. A new subspecies of L. gynochlamydeawas described, L. gynochlamydea subsp. dapanshanensis.
