Abstract

ABSTRACT Proteaceae, the Macadamia nut family, are diverse in New Caledonia with c. 50 species distributed in nine genera in tribes Embothrieae, Macadamieae, Persoonieae, and Roupaleae, where they represent an important component of the rainforest and particularly the maquis. The family is also represented by a few species in the neighboring archipelagos of Vanuatu and Fiji, which marks the eastern limit of its distribution in the Pacific. Here, we address some issues regarding generic limits within Pacific Proteaceae, using new molecular data and a review of morphology. The generic limits within the tribe Macadamieae have long been problematic, particularly amongst Kermadecia, Sleumerodendron, and Turrillia, which are part of the subtribe Gevuininae. Molecular phylogenetics shows that they form a monophyletic group, while morphological data indicate that they are only weakly differentiated. We conclude that they are better treated as a single genus, Kermadecia, as has been done previously, with eight species. Kermadecia elliptica is placed in synonymy under K. rotundifolia for the first time, and several names in the genus are lectotypified. As previously observed, we found that the New Caledonian endemic Garnieria spathulifolia is nested in Persoonia (tribe Persoonieae) from which it differs only by the number of ovules and is therefore transferred to it and a lectotype is designated.

新喀里多尼亚及其邻近岛屿的变形科Kermadecia和Persoonia的扩展一般概念

Proteaceae是澳洲坚果科植物，在新喀里多尼亚分布广泛，共有9个属约50种，分别为Embothrieae、Macadamieae、persononieae和Roupaleae，是新喀里多尼亚热带雨林的重要组成部分，尤其是猕猴桃。在邻近的瓦努阿图和斐济群岛上也有一些物种，这标志着它在太平洋分布的东部界限。在这里，我们利用新的分子数据和形态学回顾，解决了一些关于太平洋变形科属限制的问题。Macadamieae部落的属类界限长期以来一直存在问题，特别是在Kermadecia, Sleumerodendron和Turrillia之间，它们是gevuinae亚部落的一部分。分子系统发育表明它们形成一个单系群，而形态学数据表明它们只有弱分化。我们得出的结论是，它们最好被当作一个属，Kermadecia，就像之前做的那样，有八个物种。本文首次将其归为圆形叶下的同义植物，并对其属中的几个名称进行了选型。如前所述，我们发现新喀里多尼亚特有的Garnieria spathulifolia是在Persoonia (tribe persononieae)中筑巢的，它只是在胚珠数量上有所不同，因此被转移到它身上并指定了一个选型。

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.
