The phylogeography of common and widespread species helps to elucidate the history of local flora and vegetation. In this study, we selected C otinus coggygria , a species widely distributed in China's warm‐temperate zone. One chloroplast DNA (cp DNA ) region and ecological niche modelling were used to examine the phylogeographic pattern of C. coggygria . The cp DNA data revealed two phylogeographic groups (Southern and Northern) corresponding to the geographic regions. Divergence time analyses revealed that divergence of the two groups occurred at approximately 147,000 years before the present ( BP ), which coincided with the formation of the downstream area of the Yellow River, indicating that the Yellow River was a weak phylogeographic divide for C. coggygria . The molecular data and ecological niche modelling also indicated that C. coggyria did not experience population expansion after glaciations. This study thus supports the fact that Pleistocene glacial cycles only slightly affected C. coggygria , which survived in situ and occupied multiple localised glacial refugia during glaciations. This finding is contrary to the hypothesis of large‐scale range habitat contraction and retreat into a few main refugia.
