摘要

Gastrochilusbalangshanensis 是产自中国西南部四川省巴郎山的一个兰花新种，本研究对其进行了描述并绘制了插图。它在形态上类似于 G.affinis，但不同之处在于茎较短，有肾形的外果皮和近半球形的下果皮（距），先端钝圆。基于 50 个 Gastrochilus 物种的核糖体内部转录间隔（nrITS）和 4 个叶绿体 DNA 标记（matK、psbA-trnH、psbM-trnD 和 trnL-F）的分子系统学分析结果表明，巴郎山 Gastrochilus 与横断山脉特有的 G.heminii 和 G.bernhardtianus 关系密切。它是针阔混交林中的一种树枝和树干附生植物。

Gastrochilusbalangshanensis (Orchidaceae, Aeridinae), a new subalpine epiphytic orchid from the Mountains of Southwest China.

Gastrochilusbalangshanensis, a new orchid species from the Balang Mountain, Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G.affinis, but differs in having shorter stems, a reniform epichile and a sub-hemispherical hypochile (spur), obtuse-rounded at the apex. The results of molecular phylogenetic analyses based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA markers (matK, psbA-trnH, psbM-trnD and trnL-F) from 50 Gastrochilus species indicate that G.balangshanensis is closely related to G.heminii and G.bernhardtianus, also endemic to the Hengduan Mountains. The novelty is a branch and trunk epiphyte in mixed coniferous forest.

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.
