| Publ. & Syn. | Rupr., Fl. Samojed. Cisural.: 58 (1845). Syntypes: (1; UPS, S etc.) Norway: Finnmark, Alta, "Kaafjord", [1842], leg M.N. Blytt in E. Fries, Herb. Norm. fasc. 8: 70; (2; LE, UPS etc.) European Russia: "Litt. austr. insl. Kolguev", leg. F.J. Ruprecht. |
| Notes | Luzula spicata is very widespread and polymorphic. For the European variation, see Chrtek and Krísa (1962). All arctic plants seem to be 'tetraploid' (2n = 24, half-size chromosomes) and to belong to subsp. spicata. Luzula spicata does not reach the Arctic in the Pacific regions. The plants around the North Atlantic look slightly different from those around the North Pacific but no comparative study has been undertaken. |
| Chromosomes | 24. - Europe, U.S.A., Canada, Greenland. - Numerous reports. Kirschner et al. (2002a) reported 'half-size' chromosomes in subsp. spicata, i.e., a split from 2n = 12, on the authority of Nordenskiöld (1951). Not included: Reports of other chromosome numbers (2n = 12, 14, 18, 36) from alpine parts of central and southern Europe, northwestern Africa, and the Caucasus, belong according to Kirschner et al. (2002a) to several other races, see Chrtek and Krísa (1962). |
