摘要	Maianthemum is a genus with more than 35 species from the tribe Polygonateae (Asparagaceae), widely distributed between North to Central Americas and eastern Asia with high diversity in the eastern Himalayas to the Hengduan Mountains of SW China. Although most species from SW China form a well-supported Glade, phylogenetic relationships within this Glade remain unclear. With a broad level of taxon sampling and an extensive character sampling from eight DNA regions, this study intends to revisit the phylogeny and biogeography of the genus to better understand the divergence patterns of species from SW China. Phylogenetic results suggested the monophyly of Maianthemum with recognition of nine strongly supported clades, but backbone relationships among these clades remained largely uncertain. For the SW China Glade, individuals from the same species are grouped into different lineages. Our results revealed that the fast radiation of the SW China Glade was occurred in the eastern Himalayas, followed by subsequent radiation in the Hengduan Mountains in the Pliocene. Intercontinental disjunctions of Maianthemum in the Northern Hemisphere appear to have occurred multiple times during the late Miocene to the Pliocene, likely resulted by a combination of both vicariance and long-distance dispersal events.
