摘要

蝶形花科（Pteridaceae）蝶形花属（Pteris fauriei）物种之间的分界线值得商榷，该属（Pteridaceae）中一些物种的系统位置仍不明确。为了帮助全面了解该组的系统发育关系并解决分类问题，我们根据 22 个翼手目类群的五个叶绿体 DNA 区域（atpA、matK、rbcL、rps4-trnS 和 trnL-trnF）重建了系统发生树。此外，还研究了它们的孢子形态和类型材料。根据分子和形态学证据，我们做出了如下处理：var. paraemeiensis Ching ex Ching et S.H. Wu 作为 P. oshimensis Hieron 的变种；P. fauriei Hieron.austrotaiwanensis Y.S. Chao，而不是 P. latipinna Y.S. Chao & W.L. Chiou 的异名；P. omeiensis Ching 从 P. oshimensis Hieron 的异名恢复为种。

New taxonomic treatments in the Pteris fauriei group (Pteridaceae)

The dividing lines between species in the Pteris fauriei group (Pteridaceae) are questionable and the systematic positions of some species in this group remain unclear. To help comprehensively understand the phylogenetic relationships and resolve the taxonomic problems in this group a phylogenetic tree was reconstructed based on five chloroplast DNA regions (atpA, matK, rbcL, rps4-trnS & trnL-trnF) from 22 Pteris taxa. Additionally, their spore morphology and type materials were studied. Based on the molecular and morphology evidence, we made treatments as follow: P. oshimensis Hieron. var. paraemeiensis Ching ex Ching et S.H. Wu was raised as a species from a variety of P. oshimensis Hieron; P. fauriei Hieron. var. chinensis Ching et S.H. Wu was treated as a synonym of P. austrotaiwanensis Y.S. Chao, rather than a synonym of P. latipinna Y.S. Chao & W.L. Chiou; and P. omeiensis Ching was restored to species status from a synonym of P. oshimensis Hieron.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
