Species and hybrids follow the atlas inventory checked on 11 October 2026. Three newer descriptions from 2026 retain a separate source label. Higher groups reproduce de Vos and colleagues’ 2025 classification. Genera with changed names or differing circumscriptions appear in a separate branch without an unsupported higher placement.
