摘要

中国西藏自治区描述了一个兰花新种--Platanthera medogensis，并绘制了插图。P. medogensis与P. bakeriana和P. chiloglossa很接近，但很容易与后者区分开来，因为后者的唇瓣卵状披针形，基部凹陷，有两个胼胝体，粘膜线形，两个柱头位于子房下。基于五个标记（nrITS、matK、psbA-trnH、rbcL、trnL-F）的分子系统进化分析表明，P. medogensis 与 P. exelliana 是姊妹种，支持率完全一致。

A new species of Platanthera (Orchidaceae, Orchideae) from southeast of Xizang, China

A new species of orchid, Platanthera medogensis, was described and illustrated from Xizang Autonomous Region, China. P. medogensis is close to P. bakeriana and P. chiloglossa, but is readily distinguished from the latter by having ovate-lanceolate lip concave at base with two calli, linear visidium, two stigmas below the rostellum. Molecular phylogenetic analysis based on five markers (nrITS, matK, psbA-trnH, rbcL, trnL-F) revealed that P. medogensis is sister with P. exelliana by full support.

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.
