| Rumex L. | |
| Publ. & Syn. | Excluded: Rumex alpestris (see R. lapponicus). |
| Notes | Tzvelev and Elven: The subgenera Acetosa and Acetosella are distinct segregates and might be acceptable genera. We keep them within Rumex due to strong synapomorphies in flower and fruit in Rumex s. lat. |
| Chromosomes | 14 (2x). - Europe, Russia, Siberia, Far East, Canada, U.S.A., Greenland. - Numerous reports. Not included: There are several reports of 2n = 42 (6x) from southern Siberia and central Asia. These may belong to a different race or species (the otherwise Himalayan O. elatior R. Br. ex Meissn.?). The scant material we have inspected from these areas differ morphologically from the northern plants. |
