摘要/Abstract

摘要： 岩蕨科(Woodsiaceae)和球盖蕨科(Peranemaceae)历来被多数学者认为是亲缘关系密切的两个科，它们的系统位置一直存在争议，两科曾被放入三叉蕨科(Aspidiaceae)、碗蕨科(Dennstaedtiaceae)、鳞毛蕨亚科(Dryopteridoidaae)及鳞毛蕨科(Dryopteriaceae)蹄盖蕨亚科(Athyrioideae)中。根据岩蕨科1种、球盖蕨科3种、蹄盖蕨科8种、鳞毛蕨科2种及1种外类群假大羽铁角蕨(Asplenium pseudolaserpitiifolium)的cpDNA基因trnL-F区序列建立的系统树，结果显示，岩蕨科和球盖蕨科的亲缘关系较远，岩蕨科与蹄盖蕨科有密切的亲缘关系，球盖蕨科与鳞毛蕨科亲缘关系较近，岩蕨科和球盖蕨科是处于不同进化线上的植物。秦仁昌（1978）和Pichi-Sermolii（1977）的系统将二者分别作为独立的科是合适的。

Abstract: Woodsiaceae and Peranemaceae have always been considered to be two close relatives of families by many scholars, and their systematic positions have long been controversial, which have been placed in Aspidiaceae, Dryopteridoideae (Dennstaedtiaceae) and Athyrioideae (Dryopteridaceae). Nucleotide sequences of the chloroplast trnL-F region from 1 species of Woodsiacear,three species of Peranemaceae,eight species of Dryopteridaceae, two species of Dryopteriaceae and one species inoutgroup (Asplenium pseudolaserpitiifolium) were analyzed to gain insights into intergeneric relationships. The phylogenetic relationship was inferred using the neighbor-joining and maximum-parsimony methods, and both methods produced largely congruent trees. These trees reveal that: The relationship of Woodsiaceae and Peranemaceae is farther, Woodsiaceae is close to Athyriaceae, Peranemaceae is sister to Dryopteridaceae, Woodsiaceae and Peranemaceae are belong to different evolution lines. It is suitable that Ching (1978) and Pichi-Sermolii (1977) treeted them as independent families.
