Biosystematics of the pteridophytes-analysis on Hymenasplenium and Hymenophyllaceae

对于蕨类植物的生物系统学，以两组为模型。本文利用现代分子系统学技术，对水蛭科水蛭属植物进行了生物系统分析，以阐明水蛭属植物的系统发育关系。在泰国北部发现了一个独特的新种，并命名为inthanonense Hymenasplenium。对东南亚大陆已知的全部物种进行了修订，论文的编写已基本完成。对膜ophyllaceae进行了重点观察，以便为马来植物区系（Flora Malesiana）编制科，该项目已得到促进，并将准备一些额外的观察结果。虽然一般的同工酶分析技术并不完全适用于该物种，但我们对该物种的变异还是很感兴趣的。该技术的改进现已完成，下一步将获得分析物种结构所需的数据。对异毛鳞毛蕨（Dryopteris varia）进行了电泳分析，并对异毛鳞蕨的结构进行了分析，特别对其无孢子生殖进行了研究。

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.
