| Bistorta (L.) Adans. | |
| Publ. & Syn. | Excluded: Bistorta officinalis (B. major). |
| Notes | Several authors have merged Bistorta with Persicaria under the latter name. However, the majority of authors in recent years have accepted two genera (e.g., Elven 1994; Karlsson 2000b; Elven et al. 2005; Freeman and Hinds 2005). Good molecular support for this separation is found in Kim and Donoghue (2008, cpDNA and nrITS) where Persicaria constitutes one and the combined Agonogonon + Bistorta + Koenigia another main branch in the phylogeny. |
