摘要

摘要本文报道了澳大利亚烟草属Suaveolentes的9个新种，包括N.clarksonii M.W.Chase和Christenh。，N.eryteia M.W.Chase&Christenh。，N.latifolia M.W.Chase&Christenh。，N.latzii M.W.Chase，R.W.Jobson&Christenh。，N.gibbosa M.W.Chase，D.D.Andrew和J.J.Bruhl，N.olens M.W.Chase&Christenh。，N.praecipits M.W.Chase&K.Durham，N.karara M.W.Chace&Christenh。以及N.bugonia M.W.Chase和Taseski。一些已经从植物标本馆的标本中了解了很长一段时间，但在DNA研究表明它们的不同性质之前，它们与其他物种概念的区别是未知的。另一些是从一个或几个新的地方知道的。它们在形态和基因上都与近亲不同。在我们的分子研究中，对种群采样的增加使我们得出结论，最近描述的广泛分布的食虫猪笼草是一个物种复合体，包括多达六个遗传上不同的分类群，其中一个包括来自黑穗猪笼草模式地的材料。在这里，我们描述了一个新的名称，N.erytheia，用于我们之前分配给N.hesperis的所有材料，该材料在系统发育上与类型位置不同。为了使新物种之间的关系更加清晰，我们提供了一棵通过分析细胞核（RADseq）DNA数据生成的树。

Nine new species of Australian Nicotiana (Solanaceae)

Abstract. Nine new species in Australian Nicotiana section Suaveolentes are described, including N. clarksonii M.W.Chase & Christenh., N. erytheia M.W.Chase & Christenh., N. latifolia M.W.Chase & Christenh., N. latzii M.W.Chase, R.W.Jobson & Christenh., N. gibbosa M.W.Chase, D.D.Andrew & J.J.Bruhl, N. olens M.W.Chase & Christenh., N. praecipitis M.W.Chase & K.Durham, N. karara M.W.Chase & Christenh. and N. bungonia M.W.Chase & Taseski. Some have been known from herbarium specimens for a long time, but their distinction from other species concepts was unsuspected until DNA studies showed their divergent nature. Others are known from one or only a few new localities. All are morphologically and genetically distinct from their close relatives. Increased sampling of populations in our molecular studies has led us to the conclusion that the widespread, recently described species N. insecticida is a species complex, comprising as many as six genetically distinct taxa, one of which includes material from the type locality of N. hesperis. Here, we describe a new name, N. erytheia, for all material we previously assigned to N. hesperis that is phylogenetically distinct from that of the type locality. To make the relationships of the new species clearer, we provide a tree produced by analysis of nuclear (RADseq) DNA data.

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.
