• The area of origin for the blueberry tribe (Vaccinieae) is inferred as North America. • Biogeographic analysis reveals multiple, independent movements from north-temperate regions into the tropics. • Four diversification rate increases are inferred across the tribe, one of which is associated with movement into the tropics. • The finding of highly polyphyletic genera and sections of Vaccinium clarifies the necessity for infratribal reclassification. • Poorly understood and understudied tropical diversity hinders reclassification efforts. Vaccinieae is a morphologically diverse and species-rich (∼1430 species) tribe in Ericaceae. Although the majority of diversity is tropical, Vaccinieae are best known for temperate crops (i.e., blueberries, cranberries, and lingonberries) in Vaccinium . Vaccinium itself (∼500 species) has been previously suggested as highly polyphyletic and taxonomic boundaries among many of the other genera in the tribe remain uncertain. We assessed the evolutionary history of Vaccinieae with phylogenomic analyses based on a target-enrichment dataset containing 256 low-copy nuclear loci and 210 species representing 30 of the 35 genera in the tribe and 25 of the 29 sections of Vaccinium . We conducted time-calibrated biogeographic analyses and diversification analyses to explore the area of origin and global dispersal history of the tribe. The analysis recovered a temperate North American origin for Vaccinieae approximately 30 million years ago. Tropical di...
