Abstract
The big-bracted dogwood clade Benthamidia of Cornus is a typical example of the well-known eastern Asia (EA) and North America (NA) floristic disjunction, with greater species diversity in EA than in NA. The lineage provides an opportunity to explore factors contributing to the plant diversity unevenness between EA and NA and test hypotheses on the origin of disjunct distribution from a phylogenetic perspective. We generated RAD-seq data, conducted phylogenomic and biogeographic analyses for the clade with sampling of all species (9) and subspecies (10) currently recognized in floras.

Description of the data and file structure
The datasets include the sequence matrix and the SNP data of the big-bracted dogwoods, the unlinked SNPs dataset of the C. hongkongensis-C. elliptica species complex, and the reduced sequence matrix of 25 samples.
