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.

Pteris fauriei 组（蝶形花科）的新分类方法

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。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
