摘要
摘要:南美小叶蝉属。(Asteraceae, Eupatorieae)包括18种，是Praxelinae亚族的第二大属。它分布在哥伦比亚、委内瑞拉和圭亚那，到阿根廷中部、巴西南部和乌拉圭西北部。在过去的40年里，有一种植物——铁线蕨已经入侵了世界上的几个国家。为了进一步了解Praxelis及其属，本研究对Praxelis的分类进行了更新，包括将P. urticeafolim var. nanum重新建立为P. ostinoii的同义种、16个电分型、形态和地理分布的澄清、简要描述和该属所有种的首个检索。
Understanding Praxelis (Asteraceae, Eupatorieae): an updated taxonomy with lectotypifications and morphological and distributional clarifications
ABSTRACT The South American genus Praxelis Cass. (Asteraceae, Eupatorieae) includes 18 species and is the second-largest genus of subtribe Praxelinae. It is distributed from Colombia, Venezuela and the Guianas, to central Argentina, southern Brazil and north-western Uruguay. Over the past 40 years, one species, P. clematidea, has invaded several countries around the world. To understand Praxelis and its species, this study provides an updated taxonomy with the re-establishment of P. urticeafolim var. nanum as a synonym of P. ostenii, 16 lectotypifications, clarification of morphology and geographical distribution, brief descriptions, and the first key to all the species in the genus.
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.
