Abstract
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.
