For biosystematics of the pteridophytes, two groups were taken up as the models.Hymenasplenium (Aspleniaceae) is analyzed biosystematically, especially with modern techniques in molecular systematics to elucidate phylogenetic relationships among the species. A distinct new species was found in northern Thailand and named Hymenasplenium inthanonense. A revision of whole the known species in continental Southeast Asia was carried out, and the compilement of the paper has nearly been ready.Hymenophyllaceae was observed in a focus to compile the family for Flora Malesiana, which has been promoted under this project and will be ready with a few additional observations. There are species to be analyzed carefully, and variation of Crepidomanes minutus was interested, although general technique of isozyme analysis was not fully applicable to this species. Improvement of the technology is now completed and necessary data to analyze species structure will be avaialbe in the next step.Dryopteris varia was observed in electrophoretic analysis and structure of this variable species was elucidated with a special reference to its agamosporous reproduction.

在蕨类植物的系统学研究中，以两个类群为模式，对膜蕨属（Hymenasplenium，铁角蕨科）进行了系统学研究，并结合现代分子系统学技术，探讨了该属的系统发育关系。在泰国北方发现了一个独特的新种，命名为Hymenasplenium inthanonense。对东南亚大陆所有已知种进行了订正，并已基本完成了论文的编制工作，其中重点观察了膜蕨科（Hymenophyllaceae），以编制马来植物群（Flora Malesiana）的科，该科已在本项目下得到推广，并将通过一些额外的观察完成。虽然一般的同工酶分析技术并不完全适用于该物种，但仍有一些物种需要仔细分析，并对微小假脉蕨的变异感兴趣。对变异鳞毛蕨（Dryopterisvaria）进行了电泳分析，并结合其无性生殖特征，阐明了变异鳞毛蕨的结构。
