Abstract

The genus Alyxia Banks ex R.Br. is partially revised for New Caledonia, with 31 species recognised. The species complex Alyxia tisserantii Montrouz. is discussed and divided into seven species with existing names, and the synonymy is updated accordingly. Alyxia loeseneriana var. macrocarpa Boiteau is elevated to species status due to new flowering material with the name A. paniensis Lannuzel nom. nov., stat. nov. created to accommodate it, due to the preexisting Alyxia macrocarpa Koord. Detailed study of Alyxia caletioides (Baill.) Guillaumin ex Däniker revealed it was in fact made up of two distinct taxa; a new separate species, Alyxia urceolata Lannuzel, sp.nov. is therefore described. Two new species are also described following their recent collection: Alyxia humboldtensis Lannuzel & Gâteblé, sp.nov. is restricted to the summit of Mount Humboldt, and Alyxia minimiflora Lannuzel, sp.nov. is known from schistaceous cliffs around Nouméa. Finally, several nomenclatural issues are discussed, and an updated key to the genus in New Caledonia is provided.

Alyxia Banks ex R.Br. in New Caledonia: a clarification of several species complexes, nomenclatural notes, and a description of three new species新喀里多尼亚的Alyxia班克斯前R.Br.

对新喀里多尼亚的 Alyxia Banks ex R.Br. 属进行了部分修订，确认了 31 个种。Alyxia tisserantii Montrouz.的种群进行了讨论，并将其划分为 7 个现有名称的种，同时对同义词进行了相应更新。Alyxia loeseneriana var. macrocarpa Boiteau 由于新的开花材料而被提升为种，名称为 A. paniensis Lannuzel nom.对 Alyxia caletioides (Baill.) Guillaumin ex Däniker 的详细研究表明，它实际上由两个不同的类群组成；因此描述了一个独立的新种 Alyxia urceolata Lannuzel, sp.nov.。此外还描述了最近采集到的两个新种：Alyxia humboldtensis Lannuzel & Gâteblé，sp.nov.仅限于洪堡山山顶，而 Alyxia minimiflora Lannuzel，sp.nov.则产于努美阿附近的片岩悬崖。最后，还讨论了几个命名问题，并提供了新喀里多尼亚该属的最新检索表。

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.
