The floras have closing relationship in both sides of the Taiwan strait with the mutual migration and distribution. Fujian-Taiwan land bridge is a part of the most shallow in the Taiwan strait. It was revealed on the sea surface for four times that is due to the regression in Pleistocene glacial epoch, therefore Fujian-Taiwan land bridge turned into passageway of the flo-ras migration on both sides of the Taiwan strait in Pleistocene Epoch.

Key words: Pleistocene Epoch
