| Eleocharis erythropoda Steud. | |
| Publ. & Syn. | Steud., Syn. Pl. Glumac. 2: 76 (1855). Described from Ohio (U.S.A.). |
| Notes | Smith et al. (2002) reported the related but distinctive Eleocharis erythropoda from Alaska, the Northwest Territories, and Manitoba. Two of the three documented (ALA) Alaskan localities for E. erythropoda are close to the arctic boundary (at the Great Kobuk Sand Dunes in western Alaska and near Bettles in northern Alaska). We enter it as possibly present in the Borderline Arctic because this genus is notoriously under-collected in northwestern North America. |
| Chromosomes | (1) 16 (ca. 2x). - Canada, U.S.A. - Heiser and Whitaker (1948); Taylor and Mulligan (1968); Ward (1984). (2) 38 (ca. 4x). - Canada, U.S.A. - Strandhede (1967); Harms (1968); Kessler (1983). Smith et al. (2002) reported the chromosome numbers as 2n = 18, 19, and 38. They stated that the numbers 2n = 10 (Heiser and Whitaker 1948, southwestern U.S.A.) and 16 had not been verified. We have not found primary sources for 2n = 18 or 19. |
