Gnaphalieae are one of the larger tribes of the daisy family Asteraceae (Compositae) with c. 2100 species in 178 genera, occurring globally across a wide range of temperate habitats. Recent years have seen considerable advances in our understanding of their phylogenetics and evolution, but there is no widely accepted, stable subtribal classification. The present paper summarises the taxonomic history and presents the various major clades that have been named informally in phylogenetic studies. We also provide the most comprehensive phylogenetic analysis of DNA sequence data to date, including over 1000 species. Based on published studies and our new phylogenetic analyses, we suggest a subdivision of the tribe into two subtribes. These are a largely African‐endemic Relhaniinae (124 species in 11 genera) and a much enlarged Gnaphaliinae, the latter accounting for more than 90% of the species diversity (c. 2000 species in 167 genera). Although a finer division of Gnaphaliinae sensu amplo may be desirable, there are at present several obstacles to such a classification, in particular contradictory or ambiguous inferences of relationships.

修改过的部落亚目(Asteraceae)

na科是菊科菊科(菊科)的较大部落之一。178个属中的2100种,遍布全球的各种温带栖息地。近年来,我们对它们的系统发育和进化的理解有了长足的进步,但是还没有被广泛接受的稳定的亚部落分类。本文总结了分类学的历史,并介绍了在系统发育研究中非正式命名的各种主要进化枝。我们还提供迄今为止最全面的DNA序列数据系统发育分析,包括1000多种。根据已发表的研究和我们新的系统发育分析,我们建议将该部落细分为两个亚部落。它们主要是非洲特有的Relhaniinae(11属124种)和更大的Gnaphaliinae,后者占物种多样性的90%以上(167个属中的2000个物种)。尽管可能需要对Gnaphaliinae sensu amplo进行更精细的划分,但目前对这种分类存在一些障碍,特别是关系的矛盾或含糊推论。
