| Outline of Final Research Achievements |
Bryophytes (Symphyodon, Aptychella and Yakushimabryum in mosses, and Conocephalum in hepatics), which are widely distributed in Far East Asia, are studied based on morphology and chloroplast genes sequences (rbcL, rps4, and trnLF) as well as nuclear DNA (ITS1&2). In all the groups studied, it became clear that in the Japanese archipelago including Taiwan, several endemic species independent of the mainland China are differentiated. We obtained important findings in reconsidering the phytogeographical relationship between the continent and the arcs of Japan located in the eastern edge of the continent.

| Academic Significance and Societal Importance of the Research Achievements |
蘚苔類の分類学ではこれまで形態形質に重きが置かれ，中国大陸と日本列島に分布する種が形態の類似性に基づいて，同種とされる事例が非常に多かった．その実情に迫るため，極東アジアに広く分布する種を対象として，形態だけでなく葉緑体遺伝子（rbcL, rps4ならびにtrnLF等）の塩基配列の違いを精査して，蘚類シダレウニゴケ属，オオタマコモチイトゴケ属，ヤクシマコモチイトゴケ属とその近縁属，ならびに苔類ジャゴケ属について調査したところ，それらすべてにおいて，日本列島には固有の種が分化していることが明らかになった．
