| | Vaccinium uliginosum subsp. uliginosum |
| Publ. & Syn. | ?Vaccinium uliginosum var. alpinum Bigelow, Fl. Boston., ed. 2: 183 (1824). Described from Massachussetts (U.S.A.). - ?Vaccinium uliginosum subsp. alpinum (Bigelow) Hultén, Ark. Bot., n s., 7, 1: 100 (1968). |
| Notes | Alsos and Elven: This is a mainly boreal race. From molecular evidence (Alsos et al. 2002, 2005), it occurs in temperate to southern arctic parts of Europe and eastern North America and reaches the Arctic at least in Fennoscandia, Iceland, Greenland, and Canada. The North American plants are very slightly different in morphology and molecular markers and have been proposed as subsp. pubescens. However, that name is based on a Greenland plant. The Greenland plants investigated connect to Europe in molecular markers, not to North America. Young (1970a) recognized also northwestern Eurasian plants under the name subsp. pubescens, whereas his subsp. uliginosum had a more narrow range in northwestern Europe, Iceland, and southwestern Greenland. Plants morphologically resembling "microphyllum" (see below) largely replace subsp. uliginosum in the Fennoscandian mountains. These have, however, been counted as octoploids (2n = 48; Borgen and Elven 1983), conform to subsp. uliginosum in molecular markers (Alsos et al. 2002, 2005), and most probably are the same as the plants described from northeastern U.S.A. as subsp. alpinum (Bigelow) Hultén and mapped by Hultén (1968a) as such for the Fennoscandian mountains. |
| Chromosomes | 48 (8x). - Europe, Canada (E), U.S.A. (NE), Greenland (SE). - Numerous reports, e.g. Alsos et al. (2002, 33 counts). Octoploid in FCM, Alsos et al. (2002, Norway, Sweden, Finland, Denmark, central Europe, the British Isles, Iceland, southeastern Greenland, northeastern U.S.A., eastern Canada). |
