摘要	Distribution of similar taxa between the East Asia (old world) and new worlds fascinated the Botanists and Biogeographers since the Linnaean time. The current study represents phylogenetic investigation of 39 Spiraea L., species covering their entire distribution in the new world (America) to the old world (Tibet PR China). In this study we used both plastidial marker (trnL-F) and nuclear internal transcribed spacer (nrDNA ITS). Phylogeny among the species implemented in the program PAUP* while divergence time was calibrated in BEAST 1.7.5. The analysis revealed that all 39 species of the genus are monophyletic. The study further suggested that ancestors of Spiraea were in the new world but their center of diversification is in East Asia. The estimated divergence time showed that S. virginiana endemic to North America is the oldest species with divergence time 21.1 MY. The divergence time of Spiraea species with disjunct distribution in the new world, Europe and East Asia e.g., S. hypericifolia, S. chamaedryfolia, S. douglasii, S. salicifolia and S. latifolia ranged from 7.44-1.83 MY with most during Pliocene (within the last 5 MY). The results concluded that isolation of Spiraea species occurred during the severe eco-climatic fluctuations period throughout the late Tertiary and Quaternary.
