Abstract

Cistus pouzolzii is a species distributed in the western Mediterranean. Its populations are located in France and North Africa, being absent in the Iberian Peninsula.. It was described by Delile, but its taxonomic and nomenclatural status has been discussed by several authors, mainly based on its particular combination of morphological characters. We have recently found several populations of a Cistus species whose morphological characters match those of C. pouzolzii. To confirm the taxonomic identity of these populations, a comparative study was performed using herbarium specimens of C. pouzolzii from France and North Africa. In addition, two chloroplast regions were sequenced to study the phylogenetic relationships between the newly discovered Iberian populations and the rest of the species of the genus Cistus, including the sequences belonging to C. pouzolzii from France and Morocco previously used. Both analyses (morphological and phylogenetic studies) confirmed that the specimens sampled in the Iberian populations were C. pouzolzii. Furthermore, both the nomenclature of this species and its conservation status are briefly discussed.

厘清伊比利亚半岛 Cistus pouzolzii Delile 在分类学上的不确定性

Cistus pouzolzii 是一种分布于地中海西部的植物。其种群分布在法国和北非，伊比利亚半岛没有分布。它由 Delile 描述，但其分类学和命名学地位已被多位学者讨论过，主要是基于其形态特征的特殊组合。我们最近发现了几个形态特征与 C. pouzolzii 相同的肉苁蓉种群。为了确认这些种群的分类学特征，我们利用标本馆中来自法国和北非的 C. pouzolzii 标本进行了比较研究。此外，还对两个叶绿体区域进行了测序，以研究新发现的伊比利亚种群与肉苁蓉属其他物种之间的系统发育关系，包括之前使用的属于法国和摩洛哥 C. pouzolzii 的序列。这两项分析（形态学和系统发育研究）都证实了伊比利亚种群中的样本为 C. pouzolzii。此外，还简要讨论了该物种的命名及其保护状况。

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.
