Abstract

Phytogeographical study of gymnosperms in Taiwan is carried out based on reviewing data gathered from published papers on fossils, phylogeny and phylogeography. Following questions are asked. (1) How is the high degree of endemism of gymnosperm flora of Taiwan derived? (2) How many source areas of gymnosperms in Taiwan are there? (3) Is there relation between distribution pattern of endemic gymnosperms in Taiwan and those of their sister species? (4) How do gymnosperms migrate to Taiwan?
