| Elytrigia repens (L.) Desv. ex Nevski | |
| Publ. & Syn. | Nevski, Trudy Bot. Inst. Akad. Nauk SSSR, ser. 1, Fl. Sist. Vyssh. Rast. 1: 14 (1933). - Triticum repens L., Sp. Pl.: 86 (1753). Lectotype (LINN): Europe. Herb. Linn. 104.7 (Bowden 1965a: 1431). - Agropyron repens (L.) P. Beauv., Ess. Agrostogr.: 146, 180 (1812). - Elymus repens (L.) Gould, Madroño 9: 127 (1947). |
| Notes | We assume that Elytrigia repens is adventive in the Arctic but it may be archaeophytic on seashores in northern Norway and in the Murman area, perhaps also farther east. In Greenland, it remains vegetatively but does not reproduce by seeds. Other subspecies, partly littoral, are found in Europe and western Asia. |
| Chromosomes | (1) 21 (3x). - Dewey (1974, 1980). (2) 28 (4x). - Europe, Russia, Siberia. - Several reports. (3) 42 (6x). - Europe, Siberia, Canada, U.S.A. - Numerous reports, one (Bowden 1965a) with more than 150 counts. (4) 56 (8x). - Sakamoto and Muramatsu (1963); Löve and Kjellqvist (1973). (5) 63 (9x). - Dewey (1974). Löve and Löve (1975a) considered Elytrigia repens uniformly hexaploid but the reports above rather indicate a wide span and at least two main ploidy levels. For some reason (probably an editing error), Barkworth et al. (2007) reported this species with 2n = 22 and 42. |
