Abstract
Two new orchid species, Platanthera linzhiensis, P. deergongensis, are described and illustrated from Motuo, Xizang, China. P. linzhiensis is closely related to P. uniformis, but differs from it by lip yellowish green, spur yellow, nearly as long as ovary, connective obtuse-truncate, not protruding from anther, column lateral appendages ovate to oblong, slightly shorter than the anther. P. deergongensis is morphologically similar to P. contigua, but is distinguished from it by having white lip, obtuse-truncate connective and ovate to oblong column lateral appendages. Molecular phylogenetic analysis based on six markers (nrITS, psaB, matK, psbA-trnH, rbcL, trnL-F) revealed that P. linzhiensis and P. deergongensis formed a clade with high support, and are close to P. superantha.
本报告描述并图解了产自中国西藏墨脱的两个兰花新种：Platanthera linzhiensis 和 P. deergongensis。P. linzhiensis与P. uniformis亲缘关系密切，但唇瓣黄绿色，距黄色，几乎与子房等长，药隔钝截形，不突出于花药，柱状侧附属物卵形至长圆形，稍短于花药。Degongensis 在形态上与 P. contigua 相似，但有白色的唇、钝截形的药隔和卵形至长圆形的柱状侧附属物，因此与 P. contigua 有所区别。基于六个标记（nrITS、psaB、matK、psbA-trnH、rbcL、trnL-F）的分子系统学分析表明，P. linzhiensis 和 P. deergongensis 形成了一个高支持的支系，与 P. superantha 接近。
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.
