Names and checklist scope
The tree is based on the World Checklist of Vascular Plants, version 16 dated 4 June 2026, downloaded on 8 October 2026. Every accepted species has a name record. An atlas link appears beside plants with an account. Dla 157 genera had their full lists of accepted names compared with POWO on 11 October 2026. Currently accepted names have separate profiles, and former synonym links account for changes in treatment. Lower-rank taxa retain the scope of WCVP 16.
Lower-ranked taxa include subspecies, varieties and forms. Hybrids retain a label of origin. The checklist does not include unresolved names as accepted species. The POWO database accessed through the links may change after the release date.
