We compiled checklists of species of angiosperm for 140 Chinese mountain flora from previously published, comprehensive species checklists, white papers, and research papers. From our initial checklists, we excluded all nonnative species, and we reconciled taxonomy to the Leipzig Catalogue of Vascular Plants (LCVP), with infraspecific taxa combined under their respective species. Following taxonomic reconciliation and categorization within higher ranks, our dataset comprised a total of 17,576 species in 2,585 genera belonging to 251 families and 56 orders.

In addition, six dated phylogenetic trees by the V.PhyloMaker2 approach are provided.

Mountain flora data was generation based on previously published flora data by manual input. Phylogenetic reconstruction was performed in R (http://www.r-project.org/) by the package ‘V.PhyloMaker2’ .
