| Spiraea L. | |
| Publ. & Syn. | Excluded: Spiraea beauverdiana (see S. stevenii). |
| Notes | Gladkova (PAF proposal) accepted three species of Spiraea from the arctic parts: S. media, S. salicifolia, and S. stevenii. Polozhij (1988a) in addition mapped or reported S. betulifolia and S. dahurica to reach or nearly reach the Arctic in Siberia. The discrepancy is probably due to different herbaria being consulted. |
