英文摘要	Alismataceae is an aquatic or semi-aquatic herb family with a subcosmopolitan distribution. The family is one of the oldest lineages within monocots and plays an important role in the systematics, biogeography and evolutionary processes of flowering plants. However, the generic relationships of the family are still a subject of debate, and its historical biogeography is less studied. In the present study, we carried out a comprehensive phylogenetic analysis based on multiple DNA sequences (nuclear: ITS; chloroplast: psbA, rbcL, matK, rpoB, rpoC1, trnK 5' intron and trnK 3' intron; mitochondria: cob and atp1). The result supports merging Limnocharitaceae into Alismataceae as one family. Two well-supported clades were obtained based on the combined ITS, psbA, rbcL and matK dataset. Clade B consists of Luronium, Damasonium, Baldellia and Alisma: and clade A consists of the remaining genera of Alismataceae as well as Limnocharitaceae. Biogeographic analysis and Bayesian molecular dating suggested that Alismataceae originated in West Palearctic or Afrotropical area during the Late Cretaceous, and subsequently split into two clades. Clade A and clade B diversified in Afrotropical area and West Palearctic area, respectively. The intercontinental distribution of this family mainly resulted from dispersals involving migration across land bridges and long-distance dispersal. (C) 2012 Elsevier Inc. All rights reserved.
