| Poa alpina var. alpina | |
| Publ. & Syn. | L., Sp. Pl.: 67 (1753). Described from northern and central European mountains. Lectotype (LINN): Herb. Linn. 87.2 (Soreng in Cafferty et al. 2000: 254). |
| Notes | Conert (1998) and some other authors accept diploids in Poa alpina, whereas others assign these to different species (e.g., P. badensis Haenke ex Willd.). Soreng (2007) reported the lowest chromosome number for P. alpina to be 2n = 22, i.e., ca. triploid. In any case, the diploids seem to be temperate and alpine, not arctic. |
| Chromosomes | (1) 14 (2x). - Europe (C, S), Caucasus. - Several reports. See notes. (2) 21-74 (3x-10/11x). - Europe (N, C, ca. 3-10/11x), Russia (N, ca. 5-6x), Siberia (N, ca. 4-5x), Far East (N, ca. 4-5x), Alaska (ca. 5-6x), Canada (N, ca. 4-6x), U.S.A. (NW, 7x), Greenland (ca. 4-7x). - Numerous reports, i.e., more than 150 counts from Norway alone (see Engelskjøn 1979). |
