| Rumex aquaticus subsp. insularis Tolm. | |
| Publ. & Syn. | Tolm., Fl. Arct. URSS 5: 158 (1966). Holotype (LE): European Russia: "in ditione fluminis Pestschanka insulae Kolgujev", 17. Aug. 1930, leg. Z. Smirnova. |
| Notes | Subspecies insularis is reported to be restriced to Kolguev and southern Novaya Zemlya (Tolmachev 1966b). However, see notes to subsp. protractus. |
| Chromosomes | (1) 120 (12x). - Europe (N), Russia (NW, NE). - Löve and Löve (1975c, Sweden for subsp. aquaticus, near Murmansk for subsp. protractus, Kolguev for subsp. insularis), see below. (2) 140 (14x). - Europe, Russia. - At least four reports. Löve (1986) 'corrected' the report of Löve and Löve (1975c) for subsp. aquaticus, subsp. insularis, and subsp. protractus from 2n = 140 to 2n = 120 after "re-staining and re-inspection of the slides". These corrected numbers are not in accordance with the number reported both previously and subsequently from this species, even if they are not improbable. Not included: Reports of 2n = >100 and ca. 128 from southern Siberia (Belaeva and Siplivinsky 1976, for R. protractus). Fedorov (1969) referred two reports of 2n = ca. 200. |
