| 摘 要： | 对水龙骨科水龙骨亚科5属16种植物的孢子形态、叶表皮结构、叶柄和根状茎的横切、根状茎上的鳞片以及叶脉特征进行了详细的观察和分析，探讨了该亚科植物的系统位置和亲缘关系。结果表明，在该亚科植物类群中，主要分布于亚洲亚热带地区的篦齿蕨属、拟水龙骨属和水龙骨属的亲缘关系较近，而主要分布于亚洲热带地区的棱脉蕨属和亚洲温带地区的多足蕨属的系统位置则分别较孤立。

| Abstract: | An observation and analysis of series of characteristics coming from sixteen species belonging to five genera of Polypodiaeeae subfam. Polypodioideae were undertaken in order to unravel the phylogenetie relationships within this group. Spores, the structure of leaf epidermis, the transverse section of stipes, the rhizome scales and the venation patterns were selected for study. Several of these characteristics were studied in detail for this group for the first time. Morphologically and phytogeographieally, the phylogenetie relationships between these genera are eorrelated with the distribution areas. The three mainly subtropical Asia distributed genera-Polypodiodes, Polypodiastrum and Metapolypodium share a presumably close relationship, while the genera of Schellolepis from tropical Asia and Polypodium from Asia temperate zone are isolated in systematic position. |
