Abstract

ABSTRACT Molecular analyses have indicated that several Australian taxa previously identified as the red alga Plocamium cartilagineum do not group with that species as known from its northern hemisphere type locality. One of these species-level genetic groups corresponds precisely with Plocamium pusillum, a species described by Sonder in 1845 based on Preiss specimens from south-western Australia, but regarded as a heterotypic synonym of P. cartilagineum in recent morphology-based treatments. A specimen of P. pusillum in the Melbourne Herbarium (MEL) has been examined and designated as lectotype; its morphology agrees with recently collected specimens included in molecular analyses and is clearly shown to differ from authentic P. cartilagineum. Plocamium pusillum is therefore resurrected and is characterized genetically and morphologically.

分子分析表明，以前被鉴定为红藻软骨藻的几个澳大利亚分类群与从其北半球类型位置已知的红藻不属于一类。其中一个物种水平的遗传群与Plocamium pusillum精确对应，该物种由Sonder于1845年根据来自澳大利亚西南部的Preiss标本描述，但在最近基于形态学的研究中被认为是P.软骨的异型同系物。对墨尔本植物标本室(MEL)的一种普西兰(P. pusillum)标本进行了鉴定，并将其指定为选型;它的形态与最近收集的标本一致，包括分子分析，并清楚地表明不同于真正的软骨鱼。因此，Plocamium pusillum复活了，并具有遗传和形态特征。

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.
