dc.description.abstractThe Smilax hispida group (Smilacaceae) exhibits a discontinuous distribution in eastern Asia, eastern and western United States, and Mexico. A broad scale phylogeographic analysis was conducted for this group to evaluate the hypotheses of accelerated allopatric divergence in eastern Asia and a northern origin of the temperate elements in Mexico. Phylogeny was inferred using seven plastid and nuclear DNA sequences. Species delineation was assessed using genealogical sorting indices (GSI). Lineage divergence time, haplotype diversification rates, and ancestral distributions were estimated using Bayesian methods. Phylogeographic patterns in eastern Asia and North America were compared by analyzing 539 individuals from 64 populations to assess allopatric diversification. Results strongly supported delineation of six allopatric species, the origin of this group from a Mexican ancestor around 11.42. mya, and Mexican origins of the temperate species in Mexico. Significant geographic structure of haplotypes was found in eastern Asia, and greater haplotype diversification rate was observed for the North American lineage. Our data support allopatric speciation in eastern Asia but do not find evidence of an elevated diversification rate. Greater species diversity of the study system in eastern Asia may be due to a longer evolutionary history. Our results do not support northern origins of the Mexican temperate species.-
