摘要

根据形态学和质粒学数据，我们描述并证实了分布于云南省盈江县桐碧关省级自然保护区的Coptisaustrogaoligongensis是科普特斯属的一个新种。它与C.teetasubsp.teeta和C.teetasubsp.lohitensis有明显区别，主要体现在以下特征：前叶裂片相互毗连，侧裂片与中央裂片相等；植株无发达的匍匐茎；花序仅有1-3朵花；花瓣有短爪。系统发生分析表明，C.austrogaoligongensis 是 C.teetasubsp.teeta 和 C.teetasubsp.lohitensis 的姊妹。

Coptisaustrogaoligongensis (Ranunculaceae), a new species from West Yunnan, China.

Based on morphological and plastid data, we have described and confirmed that Coptisaustrogaoligongensis distributed in Tongbiguan Provincial Nature Reserve, Yingjiang County, Yunnan Province, is a new species of Coptis. It is distinctly different from C.teetasubsp.teeta and C.teetasubsp.lohitensis with differences mainly reflected in the following features: former leaf segment lobes contiguous to each other, and lateral segments equal to central one; plants without developed stolons; inflorescences with only 1-3 flowers; petals have short claws. Phylogenetic analysis indicated that C.austrogaoligongensis is a sister to C.teetasubsp.teeta and C.teetasubsp.lohitensis.

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.
