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:
Australian Systematic Botany is an international journal devoted to the systematics, taxonomy, and related aspects of biogeography and evolution of all algae, fungi and plants, including fossils. Descriptive taxonomic papers should normally constitute a comprehensive treatment of a group. Short papers on individual species and nomenclatural papers must contain significant new information of broader interest to be considered. The prestigious L.A.S. Johnson Review Series is published. Other review articles will also be considered. All papers are peer reviewed.
Australian Systematic Botany is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
