Abstract

Abstract Cynanchumpingtaoi S.Jin Zeng, G.D.Tang & Miao Liao, sp. nov. (Apocynaceae) from Yunnan Province, China, is described and illustrated based on morphological and molecular evidence. Its deeply cordate to reniform leaves and campanulate, large flowers show that it is a member of former Raphistemma Wall., which has been included in Cynanchum L.. It is different from all former Raphistemma species by the broadly ovate corolla lobes, purple-red corolla and connivent corona tip slightly exceeding the corolla throat. Meanwhile, Cynanchumlonghushanense G.D.Tang & Miao Liao, nom. nov. is proposed as replacement name for Raphistemmabrevipedunculatum Y.Wan, which was considered a synonym of Cynanchumhooperianum (Blume) Liede & Khanum but is here reinstated as a distinct species because of significant morphological differences.

来自中国的一种新种和 Cynanchum (Apocynaceae, Asclepiadeae) 的替代名称

摘要基于形态学和分子证据，描述并说明了产于中国云南省的新种Cynanchumpingtaoi S.Jin Zeng, G.D.Tang & Miao Liao（芹菜科）。它的深心形至肾形叶片和钟状大花表明它是前 Raphistemma Wall.它的花冠裂片呈宽卵形，花冠呈紫红色，靠合的副花冠顶端略高于花冠喉部，这一点与以前所有的 Raphistemma 品种都不同。Cynanchumlonghushanense G.D.Tang & Miao Liao，nom. nov.被提议作为 Raphistemmabrevipedunculatum Y.Wan 的替代名称，Raphistemmabrevipedunculatum Y.Wan 曾被认为是 Cynanchumhooperianum (Blume) Liede & Khanum 的异名，但由于形态上的显著差异，在此被恢复为一个独立的种。

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.
