英文摘要Maianthemum (Ruscaceae) comprises 28-38 species and includes the two traditionally recognized genera: Maianthemum sensu stricto and Smilacina. Thirty-seven samples representing 22 species of Maianthemum and six closely related outgroup taxa were sequenced for eight chloroplast and nuclear markers (trnL-F, rps16, rpl16, psbA-trnH, rbcL, ndhF, trnK, and ITS) with a total length of nearly 10,000 base pairs. Phylogenetic analyses supported the monophyly of Maianthemum with Maianthemum sensu stricto nested within Smilacina. Almost all species from the eastern Himalayan region in SW China except for Maianthemum tatsienense and M. stenolobum form a well supported clade. This clade is characterized morphologically by short filaments and large anthers, relatively large flowers, and pubescent stems and leaves. Maianthemum tatsienense and M. stenolobum from SW to central China form another clade. The other species from eastern Asia (central to NE China and Japan) and the New World fall into several clades. The intercontinental disjunction between eastern Asia and North America in Maianthemum sensu stricto is estimated to be at 1.68 million years ago (mya) with the Bayesian relaxed clock relying on uncorrelated rates. A recent radiation at about 2.04 mya is suggested in the high mountains of SW China, corresponding to the geographical heterogeneity in that region after the uplift of the Himalayas. Long distance dispersal by birds may have facilitated the evolution of their intercontinental disjunction and their biogeographic diversifications in SW China. (C) 2008 Elsevier Inc.
