Abstract
Rapid advances in phylogenomics using target capture methods and universal probe sets such as Angiosperms353 have enabled mass sequencing of herbarium specimens, resulting in the resolution of well-supported phylogenetic trees with thorough taxon sampling. However, the nomenclatural implementation of many now well-supported relations is lagging. Based on the results of recent phylogenomic studies we here propose a suprageneric classification of the order Oxalidales, including Brunelliaceae, Cephalotaceae, Connaraceae, Cunoniaceae, Elaeocarpaceae, Oxalidaceae, butexcluding Huaceae. One new suborder, five new subfamilies, and three new tribes are proposed. Newly recognized taxa are provided with diagnostic descriptions.
