摘要

摘要：Tephroseris属通常被认为是一个困难的属。根据对大量植物标本馆材料的检查，并考虑到现有文献，我们在俄罗斯以外的欧洲确认了七个物种。这些是沼泽T.palustris，完整T.integrifolia和亚种。整叶植物，亚种。Aurantica，亚种。头状目，亚种。maritima，亚种。蛇纹石属及其亚种。“苔原苔原”、巴尔毕香T.balbisiana、脆叶T.crispa、helenitis、长叶T.longifolia和papposa。ITS和ETS序列的系统发育分析表明，这些物种可分为三个谱系。它们是：（1）沼泽T.palustris，显然与该属的北极物种有亲缘关系；（2） T.integrifolia；和（3）剩余物种。整叶T.integrifolia谱系的分子定年结果表明，冠群年龄为176万年（0.85–287）。在俄罗斯以外的欧洲，该属分类困难的可能原因可能包括其年轻的系统发育年龄以及第四纪的广泛迁徙和遗传混合。记录并讨论了该属在俄罗斯以外的欧洲的衰落。我们认为它的下降可能与全球气温上升有关。引文：Kadereit J.W.、Laux P.和Dillenberger M.S.2021：俄罗斯以外欧洲的Tephroseris（菊科：千里光科）总览和该属衰落的注释Willdenowia 51:271–317。该记录的版本于2021年9月3日首次在线发布，随后将于2021年8月出版。

A conspectus of Tephroseris (Asteraceae: Senecioneae) in Europe outside Russia and notes on the decline of the genus

Abstract: Tephroseris is generally considered a difficult genus. Based on the examination of extensive herbarium material and considering the existing literature, we recognize seven species in Europe outside Russia. These are T. palustris, T. integrifolia with subsp. integrifolia, subsp. aurantiaca, subsp. capitata, subsp. maritima, subsp. serpentini and subsp. “tundricola”, T. balbisiana, T. crispa, T. helenitis, T. longifolia and T. papposa. Phylogenetic analysis of ITS and ETS sequences showed that these species fall into three lineages. These are: (1) T. palustris, clearly related to Arctic species of the genus; (2) T. integrifolia; and (3) the remaining species. Molecular dating of the T. integrifolia lineage resulted in a crown group age of 1.76 (0.85–2.87) million years. Possible reasons for taxonomic difficulties in the genus in Europe outside Russia may include its young phylogenetic age and extensive migration and genetic admixture in the Quaternary. The decline of the genus in Europe outside Russia is documented and discussed. We consider it possible that its decline is related to rising global temperatures. Citation: Kadereit J.

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).
