Taxonomic Status of Paragymnopteris in Pteridaceae and Its Relationship with Pellaea
摘要
Abstract
The taxonomy of Cheilanthoid ferns is difficult due to morphological convergence,and there are only five species in Paragymnopteris,the taxonomy of this genus is still controversial with its members assigned to several different genera by different scholars.In this paper,the phylogenetic relationships between Paragymnopteris and other cheilanthoid ferns based on the datasets of seven tandem chloroplast gene segments,the chloroplast genome,and the ribosomal DNA were investigated,respectively.The results showed that these three genera formed a well-supported monophyletic clade and constituted the pellaeoid group.The five species of Paragymnopteris formed two clades and each clustered with members of Pellaea.Based on the above results,this study suggested that the Pellaea should be redefined and incorporated with the Paragymnopteris into the same genus.关键词
