| Publ. & Syn. | L., Sp. Pl.: 336 (1753). Lectotype (LINN): Europe. Herb. Linn. 464.23 (Jonsell and Jarvis 1994: 154). |
| Notes | We assign the swamp, mire, and seashore plants of northeastern Norway to subsp. aquaticus. They connect morphologically to the more southern Scandinavian and European plants, whereas they differ markedly from the more upland plants in northeasternmost Norway that we now very provisionally assign to subsp. protractus. We assume that subsp. aquaticus (in this meaning) reaches also the Murman area as native as it is frequent along the seashores east to the border on the Norwegian side. The Russian plants may have been assigned to subsp. protractus, in which case the position of the very aberrant upland Norwegian plants should be reconsidered (see below). |
| 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. |
