摘要

我们描述了墨西哥瓦哈卡州特有的一个新种Polystemma。Polystemma leopardum与P. cordatum相似，但在花冠裂片的形状、花色模式、合蕊冠和花柱头的形状以及专门的栖息地方面有所不同。我们对其形态进行了描述和讨论，并提供了插图和分布图。根据世界自然保护联盟的标准，我们建议将其列为濒危保护物种。这一发现使该国的该属物种多样性增加到十种。

A new species of Polystemma (Apocynaceae, Asclepiadoideae, Asclepiadeae, Gonolobineae) from the state of Oaxaca, Mexico

We describe a new species of Polystemma endemic to Oaxaca, Mexico. Polystemma leopardum is similar to P. cordatum but differs in the shape of the corolla lobes, flower color pattern, shape of the gynostegial corona and stylar head, as well as its specialized habitat. We describe and discuss its morphology and provide illustrations and a distribution map. We propose its conservation status as Endangered under the criteria of the IUCN. This discovery increases the diversity of the genus in the country to ten species.

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.
