Abstract

Abstract: Phylogenetic analyses of DNA sequences from the plastid gene ndhF from a large number of species of the Asteraceae tribe Inuleae reveal the need for some taxonomic and nomenclatural changes. The genera Laggera, Pentanema and Pluchea as presently understood are all polyphyletic. It is concluded that the old name Vicoa should be used for three species of Pentanema, and a new species of the genus is described. Two species of Cyathocline (previously recognized as a genus in the tribe Astereae) are confirmed to be close to Blumea of the Inuleae–Inulinae and are included here in the latter genus, requiring a new combination. The new genus Galgera, sister to Antiphiona, is described for a former Laggera species. Citation: Anderberg A.

紫菀科-因纽叶科的分类新颖性及从紫菀科分离出来的一新属的描述

摘要/ Abstract摘要:对菊科伊努叶族大量种质体基因ndhF的DNA序列进行系统发育分析，揭示了在分类学和命名学上需要进行一些调整。Laggera属、Pentanema属和Pluchea属目前所了解的都是多系的。结果表明，本属的三个种应使用旧名Vicoa，并描述了该属的一个新种。Cyathocline的两个物种(以前被认为是菊科部落中的一个属)被证实与菊属-菊属的Blumea接近，并被包括在后一个属中，需要一个新的组合。新属Galgera，姐妹的Antiphiona，被描述为前Laggera种。引文:Anderberg a. a. & Bengtson a. 2022: Asteraceae-Inuleae分类上的新发现，并描述了一个新属，从Laggera分离出来的Galgera。-野生动物杂志52:373-386。记录版本于2022年12月27日首次在线发布，并将于2022年12月发行。

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
